Time-of-flight method of MR angiography.

Results of preliminary clinical studies of time-of-flight MR angiography indicate that this technique can provide accurate reproducible flow images in different anatomic regions of the body. A unique advantage of this technique is its capacity to provide multiple projections of complex vascular abnormalities with a single data acquisition. This may increase both the sensitivity and specificity of MR angiography in some patients with cerebrovascular diseases. Preliminary clinical results suggest that time-of-flight MR angiography can screen for identification of normal vasculature as well as stenosis and/or occlusions produced by atherosclerotic disease.
