METHODS: Ninety-eight patients with biopsy-proven prostate cancer underwent a CT-perfusion scan of the prostate. MTT, BF, and BV were determined and correlated with prostate-specific antigen (PSA) level, tumor load and Gleason score of transrectal ultrasonography-guided biopsy specimens.
RESULTS: Mean BF was 41.3 ml/100 ml*min-1, BV 5.2 ml/100 ml, MTT 8.7 s. Moderate correlations were observed between Gleason score and BF (0.35) and between PSA and BF (0.33) and BV (0.30).
CONCLUSIONS: CT-perfusion shows no valuable correlation with presurgical prostate cancer data.
