Conventional three-dimensional imaging uses thresholding, or surface rendering technique, which limits accuracy and detail, and hinders soft tissue definition. Volumetric image rendering preserves all CT data, not just surface boundaries, and therefore overcomes these limitations....
Four dimensional chemical shift imaging was used to map the relative peak heights of phosphorus metabolites of the liver and overlying skeletal muscle of a normal subject and two patients. The technique provides
We report two cases of rotated pectoral flaps performed following sternal debridement. The key to the diagnosis is recognition that the characteristic central area of low density represents fat and not fluid. This, along with the finding of sharply defined fascial planes and an absence of one or...
We report a case of fibroblastic proliferation of the median nerve presenting as a focal mass. This report discusses the pathological and magnetic resonance correlations and reviews the differential diagnosis for median nerve masses.
Hemifacial spasm is a symptom complex comprising involuntary, painless spasms of the orbicularis muscle that may progress to involve all facial muscles. It is frequently the result of compression of the facial nerve at its root exit zone from the brain stem by vascular loops or aneurysms of the...
A new case of spinal cord compression secondary to steroid-induced epidural lipomatosis is reported in a patient treated for dermatomyositis. Computed tomography was performed before the institution of steroid therapy, during spinal cord compression, and after effective surgical treatment. The...
The diagnosis of posterior mediastinal extension of thymus was made by magnetic resonance imaging, which showed (a) continuity of the normally placed thymus with a posterior mediastinal mass, (b) identical signal characteristics between the anterior and posterior components, (c) homogeneous...
