Abstract

Purpose: To assess accuracy of prostate measurements with and without endorectal coil (ERC). Materials and methods: Anteroposterior (AP), transverse (TX) and craniocaudal (CC) measurements were recorded from 49 prostate magnetic resonance images (MRIs) done both with and without ERC. Prostate weight was calculated as follows: AP*TX*CC*. π/6. Prostate dimensions and weight were obtained from radical prostatectomy pathology report. Results: After ERC placement, AP decreased by 0.71. cm [95% confidence interval (CI) 0.80-0.61], TX and CC increased by 0.26. cm (95% CI 0.18-0.33) and 0.25. cm (95% CI 0.16-0.35), respectively. Agreement between weight on pathology and MR was excellent: intraclass correlation coefficient (ICC) without ERC=0.96, ICC with ERC=0.90. Conclusion: Although ERC distorts measurements and despite a tendency to underestimate the prostate weight, absolute agreement between prostate weight on pathology and MRI is excellent, both with and without ERC.
