Elbow Imaging

Plain film radiographic examination of the elbows should be the initialevaluation forpatients withchronicelbowpain. Radiographs can be useful for the assessment of calcium within the joint compartment or periarticular soft tissues. Standard frontal and lateral radiographs are used for the routine evaluation of the elbow joint. Radiographic examination of the elbow has a minimal RRL. MRI […]

Tendinitis or Rupture of Other Shoulder Muscles

Tendinitis and rupture also can involve the subscapularis, infraspinatus, and teres minor, or biceps tendons, although far less commonly than the supraspinatus. Early tendinitis involves an increased signal intensity area within the tendon. This can progress to frank rupture of the tendon with a high–signalintensity area at the site of the tear on T2-weighted images […]

Shouder Instability and Disruption of the Antetior Capsular

For the assessment of shoulder instability and labral tears, it is imperative that intra-articular contrast medium be injected in order to be able to evaluate the entire articular labrum, glenoid fossa, and capsular mechanism (12). Axial MR images provide the best visualization of the anterior and posterior glenoid labra, capsule, and lower rotator cuff muscles […]

Shoulder Imaging Overview

Plain film radiographic evaluation of the shoulder should include frontal examinations with internal and external humeral rotation. If there is a question of instability or dislocation, an axillary view, a scapular Y view, or both should be obtained. There have been several reports that recommend the use of a 30-degree caudad-angled radiograph or a suprascapular […]

Musculoskeletal Imaging Overview

The advent of the multidetector CT (MDCT) scanner has increased the applicability of this imaging technique for the assessment of the musculoskeletal system. This technology allows for the acquisition of large data set in the axial plane that can be reconstructed in multiple planes of imaging with the use of multiplanar reconstruction (MPR) algorithm. Any […]

Diffuse Idiopathic Skeletal Hyperostosis

Diffuse idiopathic skeletal hyperostosis (DISH) is not really an arthropathy because it spares synovium, articular cartilage, and articular osseous surfaces. It is a fairly common ossification process involving ligamentous and tendinous attachments to bones and occurs in 12% of the elderly (55). It most commonly affects the thoracic spine but also may involve the pelvis, […]

Calcium Pyrophosphate Dehydrate Deposition Disease

It is also known as pseudogout and has the classic triad of pain, cartilage calcification, and joint destruction. Chondrocalcinosis at the knee, wrist, or symphysis pubis is virtually diagnostic of calcium pyrophosphate dehydrate deposition disease (CPPD) (Fig. 6-42). FIGURE 6-42. Chondrocalcinosis. Frontal radiograph of the right knee. Calcifications (arrows) are present within the medial and […]

Gout Imaging

Gout is a metabolic disorder that most commonly involves the feet, especially the first metatarsophalangeal joint, as well as the ankles, knees, hands, and elbows in asymmetric fashion. It is produced by a deposition of monosodium urate crystals in tissues with a poor blood supply, such as cartilage, tendon sheaths, and bursae. The radiographic features […]

Rheumatoid Arthritis Imaging

Rheumatoid arthritis is a connective tissue disorder of unknown etiology that can affect any synovial joint in the body. It is a bilaterally symmetric inflammatory degenerative disease that involves the following joints in order of decreasing frequency: : Small joints of the hands and feet, with the exception of the distal interphalangeal joints Knees Hips […]

Osteoarthritis Imaging

Osteoarthritis or degenerative joint disease (DJD) is an asymmetric, usually bilateral mechanical degenerative process that involves joints significantly involved in weight bearing, such as the hip, knee, and spine, and those involved in frequent repetitive mechanical trauma, such as the distal interphalangeal joints of the fingers, trapezium–first metacarpal joint, trapezium- scaphoid joint, and metatarsophalangeal joint […]
