Contrast and optimal scan parameters of T 1-weighted MR imaging at 3 . 0 T : evaluating with using computer simulation software

PURPOSE Recently, 3.0 Tesla (T) magnetic resonance imaging (MRI) has been widely introduced to routine clinical use, and some advantages of the higher field strength have been reported. However, there are few reports in the literature about the signal intensity and contrast changes induced by relaxation time changes between 1.5 and 3.0 T. Some papers have reported discrepancies regarding the contrast on T1-weighted images at 3.0 T. The purpose of this educational exhibit is to demonstrate the contrast change of T1-weighted images (T1-SE and T1-FLAIR) depends on static magnetic field strength change with using computer simulation software we developed.
