Abstract:
Objective To investigate the influence of d iagnostic needle biopsy (prior to MRI) on the magnetic resonance imaging (MRI) s taging of prostate cancer. Methods Ten patients suspicio us of prostate cancer were enrolled in this study.MRI was performed both prior t o transrectal sextant biopsy and a week after biopsy.The MRI staging of prostate cancer before and after biopsy was compared. Results Al l the 10 patients were classified as stage B before biopsy,while 9 of the 10,wer e classified as stage C 6～8 days (mean,7 days) after biopsy.The post-biopsy MR I staging was higher than that of pre-biopsy because of bleeding due to biopsy. Conclusions When MRI examination was performed within o ne week after needle biopsy,the MRI staging of prostate cancer would be influenc ed because of bleeding due to biopsy.Our data suggested that MRI should be perfo rmed prior to needle biopsy in suspicious cases of prostate cancer.
