MR Imaging with Stir Technique and Air Insufflation for Local Staging of Bladder Neoplasms

Comparison between Conventional and Fast Spin-Echo Stir Sequences

“…The STIR sequence is very sensitive to pathological lesions, because of the high signal intensity of le sions with long Tl and T2 relaxation times and a si multaneous suppression of the interfering high sig nal of fatty tissue (1,3,9,18). In addition, fat sup pression reduces artifacts.…”

“…STIR sequences, benefit from a high contrast between normal and pathological tissue and suppression of the fat signal (1,3,9,18). Long scan ning times, however, reduce the value of STIR se quences for routine imaging.…”
