Appearance of venous malformations on magnetic resonance imaging.

The magnetic resonance (MR) imaging appearance of venous malformations, all angiographically verified, was evaluated in 11 patients. A venous malformation is characteristically depicted as a tubular area of decreased signal intensity in the white matter of the brain. In one patient, a histologically verified cavernous malformation was also present with a characteristic mixed signal-intensity core on the T2-weighted MR images. Care should be used when evaluating venous angiomas to exclude the presence of a lesion with associated prominent venous drainage, such as a glioma.

Utilization of computed tomography scanners and the health planning issue: a process data summary.

Studies were made of the computed tomography (CT) scanning process at three hospitals. The data collected, while of interest to hospital administrators and radiologists, are particularly significant in view of the current structure of health planning guuielines. The data show clearly that the utilization potential of a particular CT scanner is a function of patient demand, scan time, the ratio of head to body procedures, and medical practice insofar as contrast medium administration is concerned. This paper summarizes the results of the hospital studies and documents the implications of the data for health planning guidelines.
