of the brain, fast MR imaging, and imaging of malignancies of the extracranial head and neck. Rounding out the program were 14 “case ofthe minute” presentations, in which speakers very briefly discussed individual cases of special interest; technical exhibits provided information on new products publications specifically pertinent to neuroradiology.

For the fourth year, the Gabriel Wilson Award was given to the scientific paper judged to be the best presented: Wayne L. Davis (Salt Lake City, UT) received the award for the presentation of “International MR Angiography: Comparison of Three-Dimensional Time of Flight and Multiple Overlapping Thin-Slab Acquisition Techniques.” The MR Angiography section below contains a summary of this paper by Dr. Davis, D. D. Blatter, D. L. Parker, and H. R. Hamsberger. At this meeting, second-place honors were awarded for the first time, and two presentations tied for this distinction: “A Rheologic Basis for MR Angiography. I. The Carotid Bulb” by C. W. Kerber, C.
