FIG 2. A 35-year-old man with low-grade astrocytoma.
A, T2-weighted image at 3700/96/1 (TR/TE/excitation). Left frontoparietal tumor with hyperintensity is not enhanced after contrast medium administration.
B, Contrast-enhanced T1-weighted image at 690/14/1.
C and D, SE-EPI at 2000/97/1 (C) and GE-EPI (D,) at 2000/46/1. On the perfusion-sensitive MR imaging, tumor CBV (arrow) is lower than that of gray matter obtained with the two techniques.
