Alteration in muscle T2, notably T2 prolongation due to increased intracellular or extracellular free water (muscle edema), is best detected with inversion-recovery and fat-suppressed T2-weighted images (, 1,, 2 ). However, when T2 and D* are both decreased as with many prostate tumors, the T2 contrast is negative and the D* contrast is positive. However, continued development of new brain T2/FLAIR lesions could lead to new attacks and thinking problems such as short-term memory loss or trouble keeping track of multiple tasks at the same time.
