Objectives

Narrative objectives1

The purpose of this study is to clarify the clinical significance of dynamic contrast-enhanced MRI in multiparametric MRI by analyzing the relationship between the contrast enhancement and histopathological factors, treatment evaluation, prediction of treatment effect, predicting prognosis after treatment and the impact of dynamic contrast-enhanced MRI on practical clinical reading in patients with prostate cancer diagnosed by multiparametric MRI, MRI-guided biopsy or total prostatectomy due to elevated PSA levels.

Results

The PI-RADS category, qualitative enhancement effect, and tumor size were significantly lower in GS=3+3 lesions than in GS3+4 or higher lesions. The proportion of pattern 1 enhancement was significantly higher in GS=3+3 lesions than in GS3+4 or higher lesions.
In TZ PI-RADS category 3 lesions, the frequency of pattern 2 and 3 contrast patterns was significantly higher in GS=3+4 or more lesions than in GS=3+3 lesions.

Baseline Characteristics

Male patients with a increase in PSA levels or suspected prostate cancer who underwent a 3.0T prostate multiparametric MRI examination and were diagnosed with prostate cancer histopathologically.

Participant flow

Eligible for inclusion in the study were 419 consecutive male patients with elevated PSA levels or suspected PC who underwent 3.0T prostate multiparametric MRI, including T2-weighted imaging, DWI, and DCE-MRI as well as MRGB of lesions suggestive of PC between October 2019 and March 2023. Of the 419 patients, 188 were excluded for the following reasons: diagnosis of benign prostatic condition by MRGB (n = 174); previous therapy including radiation therapy, radical prostatectomy, or bacillus Calmette-Guerin (BCG) administration for bladder cancer (n = 13); and prostatic neuroendocrine tumor (n = 1). After applying these exclusion criteria, 231 patients were included in this study. This study was approved by the ethics committee of our facility, and patient consent was obtained using the opt-out method.

Adverse events

None
