The type of contrast injected into the joint depends on the subsequent imaging that is planned. For pneumoarthrography, gas is used, for CT or radiographs, a water-soluble radiopaque contrast, and for MRI, gadolinium. Double-contrast arthrography can be used for more anatomically complex cases, though its use is relatively infrequent.
Septic arthritis is the purulent invasion of a joint by an infectious agent [5] [6] with a resultant large effusion due to inflammation. [7] Septic arthritis is a serious condition. It can lead to irreversible joint damage in the event of delayed diagnosis or mismanagement. It is basically a disease of children and adolescence. [6]
Joint effusion and limited range of motion are common associated features. It affects primarily large joints, including knee (>50% of cases), elbow, hip, and shoulder. SOC is twice as common in men as women. Some patients have intra-articular bodies resting in stable positions within joint recesses or bursae.
Arthrocentesis, or joint aspiration, is the clinical procedure performed to diagnose and, in some cases, treat musculoskeletal conditions. The procedure entails using a syringe to collect synovial fluid from or inject medication into the joint capsule .
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury in children. [13] For acute abdominal pain in adults, an abdominal X-ray has a low sensitivity and accuracy in general. Computed tomography provides an overall better surgical strategy planning, and possibly less unnecessary laparotomies.
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases. For example, an abdominal aortic angiography is taken in the arterial phase in the abdominal level, and is useful to detect for example aortic dissection. [10]
Symptoms include swelling in the elbow, which can sometimes be large enough to restrict motion. There is pain originating in the elbow joint from mild to severe which can spread to the rest of the arm. If the bursa is infected, there also will be prominent redness and the skin will feel very warm.
