FIG 2. A 64-year-old woman undergoing screening owing to a family history of aneurysms.
A and B, 1.5-T (A) and 3.0-T (B) TOF collapse images. The distal middle cerebral artery branches are better visualized on the 3.0T MR angiogram.
C and D, 1.5-T (C) and 3.0-T (D) subvolumes demonstrate a 4-mm anterior communicating artery aneurysm. The wall of the aneurysm is more sharply displayed and the adjacent anterior cerebral arteries better separated from the aneurysm on the 3.0-T study. (From Bernstein et al (8).
