  • Abstract
  • Look Inside

In this study, bladder tumors were examined with SMT-50 (0. 5 Tesla) MRImaging system, using conventional spin echo sequence and gradient refocused echo sequence, a kind of fast scan technique. Routine T1, T2 weighted MRImaging of SE sequence showed poor contrast between tumors and normal urinary bladder mucosa. Newly developed gradient refocused sequence were composed of SSFP (Steady State Free Precession) with an flip angle 90°, TR 500~1000 ms, TE 20 ms, respectively. SSFP was quite suitable for distinguishing bladder tumors from other lesions.
