Introduction

MRI-targeted biopsy and MRI-targeted treatments for prostate cancer are often carried out by urologists specializing in this area, however we depend on expert Uroradiologists to interpret and convey MRI information. In an image-guided treatment driven era, MRI interpretation for use in interventional prostate cancer procedures is an important skill for Urologists to develop if they wish to perform accurate MRI-targeted prostate biopsy and treatment. We aimed to establish whether MRI interpretation skills could be gained by Urologists after a 2-day training course.

Methods

A 2-day training course in prostate MRI interpretation was delivered to 25 Urologists by a panel of expert Uro-radiologists._x000D_ _x000D_ Participants were assessed on their ability to interpret prostate MRI in a 2-hour test at baseline (test 1) and after teaching (test 2). Scans were chosen at random from a database of all men undergoing pre-biopsy multiparametric MRI followed by transperineal template biopsy at our institution. _x000D_ _x000D_ Prostates were scored by participants on a 1-5 Likert scale for suspicion of prostate cancer and compared to histological findings from transperineal template prostate biopsy. The average area under the curve (AUC) for the detection of clinically significant cancer (Gleason >= 3+4 and/or maximum cancer core length >= 4mm) was calculated for the group. The likelihood of extracapsular extension, involvement of urinary sphincter and participants’ confidence in their interpretation was also rated on a 1-5 Likert scale.

Results

The AUC for the detection of clinically significant cancer on a patient level from Test 1 was 0.59, 95% CI [0.55-0.65]. The AUC for the detection of clinically significant cancer from Test 2 was 0.74, 95% CI [0.70-0.79]. There was a significant improvement in participant’s average AUC after teaching, difference 0.15, 95% CI [0.09 - 0.2]. Mean confidence of participants in prostate MRI interpretation also improved significantly before and after teaching from 3.19 to 3.53 (p<0.0001).

Conclusions

Prostate MRI interpretation is an important skill that is transferrable to the Urologist. After a short teaching course, urologists improved significantly at detecting cancer. Whilst we will always require expert Uro-radiologists to report prostate MRI, courses in prostate MRI interpretation should be considered in the training of Urologists involved in MRI-targeted prostate biopsy and treatments.
