[Differentiation of cicatricial fibrosis and recurrence of gynecological tumors by MRI].

In a retrospective analysis the relative signal intensities in recurrent tumours of gynaecological origin (n = 16) and in areas of pelvic fibrosis (n = 24) were evaluated. MRI was able to assess biopsy-proven recurrences in 15/16 patients. In one female MRI was false-negative (submucosal tumour spreading), in another case false-positive (reactive lymphnode hyperplasia). Early fibroses (1-12 months following tumour treatment) were of higher signal intensity that late fibroses (time interval since treatment more than 12 months). Differentiation of recurrent disease from post-treatment fibrosis was optimized by long TR (2500 msec), long TE (80-100 msec) spinechopulse sequences.
