Other Hip Abnormalities

Another hip region imaging application of potential interest to physiatrists involves the use of technetium bone scanning to evaluate recently described “thigh splints” caused by exaggerated stride length by short female basic trainees in the unisex-oriented military (34). Seven cases of thigh pain in female recruits at one military base were imaged after administration of […]

Femoroacetabular Impingement of the Hip

Femoroacetabular impingement is another cause of hip pain that may initially have a non–specific clinical presentation; however, a thorough physical evaluation should be able to identify this condition. Pain can be elicited on physical exam by passive movement of the thigh into full flexion, adduction, and internal rotation (34). Radiographs often help to identify anatomical […]

Ischemic Stroke Imaging

Cerebral ischemia can be produced by thrombosis of large extracranial or small intracerebral vessels, emboli originating from atherosclerotic plaques or thrombi within more proximal vessels or the heart. In addition, decreased perfusion of systemic origin, such as shock, decreased cardiac output, or respiratory failure can also cause cerebral ischemia with or without infarction, Cerebral ischemia […]

Degenerative Spine Disorders

CT and MRI provide complementary information about degenerative diseases of the spine. MRI is often the modality of choice in assessing degenerative changes within the spine due to its superior soft-tissue contrast. CT has superior spatial resolution and provides better conspicuity of osseous and calcified structures. The advent of MDCT technology allows for superb reconstruction […]

Ischemic Necrosis of the Hip

One of the common indications for MRI of the hip is to are the standard radiographs performed for the assessment determine the presence of ischemic necrosis. This is bone of hip joint abnormalities (26). The presence of osteoarthri death produced by a compromised blood supply. It also has tis, bone tumors, and soft-tissue calcifications can […]

Carpal Tunnel Syndrome

MRI can serve as an adjunct diagnostic tool for CTS when the clinical or neurophysiologic findings are equivocal. The carpal tunnel is a fibro-osseous space with little fat that contains the flexor tendons and the median nerve. The flexor retinaculum composes the volar aspect of the tunnel and normally shows slight palmar bowing. The median […]
