Before the procedure, be sure to read the existing contraindications!
Preparation for tomography
Preparation is only needed before CT of the elbow joint with contrast. In this case, the procedure must come on an empty stomach.
How the procedure passes
The patient lies on his back on a flat horizontal surface. Around the elbow joint moves the element of the tomograph, in shape resembling a ring. With a diagnostician who monitors CT from a distance, you can communicate through two-way communication.
Diagnosis does not cause discomfort. Its duration is about a minute, with a contrast of about 20 minutes. The results of tomography are ready in half an hour after its completion. The doctor gives the patient pictures, as well as their description.
Alternative diagnostic methods
If the patient has already transferred several radiographic examinations in a row, then MRI( magnetic resonance imaging) is recommended. This method is more effective for studying soft tissues in the elbow joint area. CT scans better visualize the pathologies of bone structures, and fluid-filled formations. If there are appropriate indications, the doctor may recommend ultrasound or a radioisotope study.
Arthroscopy is used to visualize intraarticular surfaces. This invasive technique involves the insertion of a probe into the joint cavity. The study of the nature of the joint contents is performed by means of a puncture. In this case, the tissue sample is withdrawn for further analysis.
Contraindications and effects of research on human
Radiation obtained by scanning the elbow joint will not affect the patient. But the contraindications for the procedure are:
- the state of pregnancy in any trimester of , since even a minimal dose of radiation can have a negative impact on the development of the baby;
- the age of the patient should be more than 14 years old ;
- allergic reactions in contact with iodine-containing drugs ;
- excess weight of the patient , since the devices are designed for a patient's weight not more than 120 kg;
- general severe condition of the examined person ( acute cardiac, renal and other insufficiency).Especially it should be borne in mind if a procedure is planned with the use of contrast, since its introduction can adversely affect the patient's condition.
- breastfeeding is also a limitation of the .If CT examination with contrast composition is necessary, a break between procedure and feeding should be observed at 48 hours, as the contrast composition enters the breast milk.
Preparing for diagnostic
Preparing for an elbow computed tomography procedure is extremely simple and is only necessary if a study using an iodine-containing contrast medium is planned. In this case, you should stop taking food 5 to 6 hours before the procedure. To carry out a conventional CT scan, such limitations are not required.
It will be enough for the patient to get rid of ornaments that contain metal, as their contours on the received pictures can distort the results.The patient is informed that in case of using contrast in tomography, unpleasant symptoms may appear: salty taste in the mouth, headache, nausea. These are normal phenomena.
When a patient suffers from claustrophobia or is anxious, sedatives may be prescribed.to the table of contents ↑
Features of the CT of the elbow joint
The examination and visualization of the elbow joint will allow to fix possible changes in the joint, its shape, structure, possible ruptures of blood vessels and nerves. Most often this method is used as a refiner for the final diagnosis. The procedure will continue for 5 to 20 minutes, depending on the type of tomography.
During this time the device will fix the image of the elbow joint in the desired planes and positions. At that time, which the patient will be on the movable table of the tomograph, one will have to try to stay still. This is required to obtain clear images.
After scanning, you can go home. The patient will be given on hand the results - pictures, their description by a specialist or a disk on which all the research materials are fixed.to content ↑
In most cases, the elbow joint tomography is necessary without contrast. Apply it in those cases when one-time examination of the joint and the study of the blood vessels of the hand( angiography) are necessary. The contrast itself consists of iodine-based medications.
Method of introduction of contrast composition - intravenous .
The body is released from the contrast medium after the expiration of a day - one and a half.to content ↑
A specialist who performs an elbow joint scanning procedure is likely to inform the patient about the apparent problems after completing the procedure. He will advise which doctor should be contacted in the future.
It will be a traumatologist if pathological processes or changes triggered trauma.
Inflammatory joint diseases require a visit to a therapist or rheumatologist.
Various tumors of bones and surrounding tissues imply a visit to the oncologist.
The cost of the procedure
The price of the procedure for scanning the elbow joint will depend on the following factors:
- of the area of the body portion being surveyed;
- kind of scan required - simple or with contrast application.
The price includes a doctor's opinion, large format pictures in the right amount, a DVD with a scan.
In some clinics there is a CT service without description. In this case, only pictures or a record on the disc are given on hands, without the conclusion of a specialist. The price for this service will be slightly lower than with the description.
On average, the price for Moscow computer scan of the shoulder joint will be from 4 to 4 thousand 500 rubles without contrast, from 8 to 10 thousand rubles with contrast.

CT of the elbow joint
The ulnar fold is of a very complex structure, because in the process of developing the arm this organ has become sufficiently multifunctional and from the support has evolved into a grasping. The elbow joint includes three separate joints - the brachial, radicular and pleural membranes. They are united by a capsule from connective tissue - cartilage. All this, of course, greatly complicates the structure, and the more complex and functional the structure, the more likely it is that functional disturbances will arise in it. The first method for examining the bones is fluoroscopy, but if necessary, examine the adjacent cartilage and the tendon, it is not suitable. Then a computed tomography, or CT of the elbow joint is used.
Indications and contraindications to the application of the CT technique of the joint
The CT technique is also based on the use of X-rays, but in this case the effect is not scattered, and beam-like - when the CT of the joint, no shadows appear on the image, and the image itself has a high resolution and is layered, which dramatically increases its diagnostic information. After all, the data enters the computer and is processed using a special program, which means that the image was originally digitized. The doctor, thus, can increase the required area and obtain an image of even the smallest details. All this is possible due to the sharp development of CT techniques of joints in the last decade - the sensitivity of the equipment has increased significantly, the qualification of medical personnel also does not stand still, which means that the details of the data will only increase.
So, if a patient is suspected of such diseases as arthritis and arthrosis, osteochondropathy, tumors of various etymologies, as well as trauma, accumulation of fluid in the elbow joint, internal fracture of the joint or anomaly of development - the doctor will most likely direct you first to fluoroscopy. And if this procedure does not reveal anything, then on CT of the elbow joint, which will accurately show whether there is pus in the ulnar capsule, whether growth of neoplasms in adjacent tissues is observed, and will be able to determine the functional condition of the elbow joint.
This technique is harmless, the radiation load is small and rather conditional. However, she also has contraindications. For example, CT can not be performed during pregnancy, since the effect of X-rays even of low intensity on fetal development is unpredictable. Secondly, if the procedure requires the use of a special contrast agent, and the patient does not carry out an allergy to the substance( on the iodine component), or conducts the CT without compulsion, reconciling with the inevitable loss of the informative value of the examination. Thirdly, this examination is technically impossible to carry out for patients with a body weight of more than 200 kg.
Advantages of CT and how it is performed
So, to the advantages of CT of the elbow joint is its high accuracy, first, thanks to layer-by-layer image removal, secondly, high and growing accuracy of the equipment, and third, the possibility of post-processing images forscaling and obtaining three-dimensional images. The tomograph assesses the condition of the tissues, finding differences in the density of even 1%, which makes the CT technique of joints the foremost in such branches of medicine as oncology. In addition, the possibility of computed tomography may also be useful in assessing complex injuries in trauma.
The procedure is carried out this way: the patient is placed on the pull-out table, which is then placed in the tomograph chamber. The whole process takes up to one minute, the tomograph camera itself is illuminated and well ventilated. It is not so close as to cause a claustrophobia attack in a patient. After the procedure, the results will be ready and processed within an hour, then handed out or sent by e-mail. CT of the joint, conducted with contrast, is performed on an empty stomach, but if no contrast is required, then no special preparation is also conducted.
CT of the elbow joint refers to the advanced techniques of clinical diagnosis and is usually not used immediately, but for clarifying or setting a complex diagnosis at a certain stage of the examination. Almost all problems that arise with the elbow joint and adjacent soft tissues can be recognized and localized using the CT technique.

. The features of the method of computed tomography of the elbow joint are likely to be analyzed in the case of a clinical case.
Patient o., 51, contacted the hospital of traumatology with complaints of pain in the crunch, restriction of movements in the right elbow joint. Ill for 3 months, connects the appearance of complaints with the trauma of the hand( in the ice fell and hit a bent elbow on the ground).To reduce the pain used anti-inflammatory ointments to doctors did not apply.
unpleasant feelings passed for 2-3 weeks, but immediately after that began to appear again. A month ago, a lady on the advice of a surgeon made a radiograph of the affected joint, from her words, the analysis revealed osteoarthritis and osteoporosis. Calcium and non-steroidal anti-inflammatory drugs were prescribed, but pain in the joint continued to bother.
in the clinic was sent to the patient for computed tomography of the elbow without contrast enhancement, which was recommended for assessment of joint condition and exclusion of the consequences of trauma. The tomograms were determined in the past revealed osteoporosis and violations of the type of osteoarthritis, no signs of joint damage were found. The lady was sent to a rheumatologist, she was prescribed funds for the treatment of osteoporosis and osteoarthritis, physiotherapy, therapeutic gymnastics. Little by little the patient's well-being improved, the pain in the joint worried had almost ceased.
on what the method of the elbow joint is based and that it shows the
During the elbow joint analysis it is scanned by X-ray radiation. Rays unequally pass through structures of different density because of this, as a result, layered images of limb tissues are produced, where many pathological changes and distinctive features of the construction of the elbow joint are clearly visible.
The pictures perfectly show its main components: the connected bones( the lower part is the shoulder, the upper one is the ulnar and the ray one) and the contours and cartilage tissue, the joint capsule and the joint slot. Having studied the structure of a certain number of successive "layers", we can confidently judge the presence of such types of pathological processes as inflammatory( arthritis), destructive( arthrosis) changes, developmental anomalies, lesions, tumors, and so on. Due to a sufficiently high accuracy, the computer tomography system is quite useful in determining violations from the elbow joint, which is a fairly complex structure in education.
Which structures are poorly visible on the elbow joint
How accurately established and known, the CT is optimally suited for bone analysis: the denser the tissue, the more clearly it is visible in the photo. Soft fabrics other than this are indicated in photographs, although not with the greatest possible clarity( depending on the mode of operation chosen, the apparatus).Of course, it is worth acknowledging that tendons, ligaments and muscles are seen in photographs many times less than in mrt, because if you need to get information about these structures, you should resort to the appropriate analysis.
why, the analysis was performed without contrast
According to the doctor, the patient from the described clinical case had the results of a traumatic elbow injury suffered some time ago. In such situations, contrasting is useless. Older changes in bones and joints are not accompanied by the formation of tissues that differ in their ability, actively accumulate contrast and more clearly identify themselves in images, which is why, with and without intensification, the photographs are then practically identical.
When an elbow joint exists with the contrast of
, CT of the elbow joint is required in a rather small number of cases. Almost always it is strongly advised in case of suspected neoplasm of the joint or periarticular tissues and at the time when it is necessary to analyze the vessels of the upper limb in order to find, for example, possible violation of blood circulation immediately after an elbow injury. The need to use contrast appears infrequently, almost always the process is carried out without it.
Than the elbow joint is much better, is there a way to change it?
For completely different diseases and injuries of the elbow, the doctor examines and, if there is a reason for this, assigns x-ray, analysis. In the photographs, making in 2 projections, the bones connecting with each other by the elbow joint and the violation of their mutual position, the presence of fractures, dislocations, osteophytes and other, anatomical changes are seen a little. On the basis of these received these usually can be diagnosed. Unfortunately, radiography does not "see" soft tissue and does not distinguish between small formations, which is why it is good and reliable not in all cases. In addition, it is characterized by an average radiation load, which is why it can be repeated a limited number of times. There is superiority in KT-it is safer and more practical information is obtained, which makes it possible to apply it even in the most difficult situations, when additional procedures provide strange results and also do not find any pathology at all.
Cartilage, ligaments and tendons of the elbow joint are almost impossible to examine by roentgenologically, but they are well distinguished by ultrasound, analysis. In order for it to be true, it is necessary to direct the sensor to the area under investigation in a particular projection, therefore, for the most accurate diagnosis, the participation of an experienced master is required. Ultrasound makes it possible to make decisions about the homogeneity of the studied structures and their echogenicity - in simpler terms, tissue density. Unfortunately, the dice are inaccessible to visualization by resorting to the services of this procedure, and they show a signal directed at them. Computer tomography in some situations is an order of magnitude much better than ultrasound for the quality of visualization, but it also has some disadvantage in comparison with it: kt gives a small radiation load, because of this, it can not be used in all patients.
To "look inside" the joint, there are 2 diagnostic procedures: this, arthroscopy and puncture of the joint capsule with the intake of fluid from its cavity. Arthroscopy makes it possible to directly process information and try to understand the inner surface of the capsule by resorting to the services of a miniature camera that was inserted inside. This is unpleasant, potentially traumatic and insistently requires anesthesia, but thanks to arthroscopy, you can not only find out much valuable, but also perform a mini-operation, for example, to cross the intraarticular spikes and also to extract a fragment of the damaged cartilage. Resorting to the services of kt, how easy it is to think, it is almost impossible - tomography is considered a non-invasive procedure. Puncture of the joint and microscopy of the liquid can not say anything at all about the structure, but it makes it possible to find out about the composition of the contents of the joint: pus, blood, the presence of leukocytes, bacteria and so on. This is very valuable for diagnosis.
CT of the elbow joint is replaced by MRT;In addition, from time to time, magnetic resonance imaging, suitable for the study of soft tissues, is even slightly more preferable.
What other diseases can find the elbow joint
- arthritis and arthrosis of the elbow joint;
- fresh injuries of the elbow( hematoma in soft tissues, dislocation, fracture in the joint region, etc.);
- chronic injuries of the elbow joint;
- signs of rheumatic changes in the elbow joint( with rheumatoid arthritis, arthritis, lupus, and so on.);
- tumors and metastases in the region of the joint and periarticular tissues, etc.
Can complications occur immediately after the elbow joint
The procedure, if performed in a person who has no limitations to it, is great for joint examination and differs sufficientlyhigh level of security. Even in spite of the fact that during it human exposure to X-rays, the amount obtained is so small that it has no effect on the course of the disease and does not cause any deviations in health afterwards.
whether to prepare for the elbow joint
H, analysis with contrast is worth to come on an empty stomach, and with a "simple" spiral, as well as multispiral kt to change their lifestyle is not required.
