“…Apart from investigating image quality, some authors already conducted studies comparing the diagnostic accuracy of various coil setups. For local cancer staging, the use of an ERC as compared to PPA receiver coil equipment alone seems favorable, particularly at lower field strengths [22,23]. Therefore, the European Society of Urogenital Radiology still recommends to use the ERC for local staging of prostate cancer on a 1.5T MRI in their recently updated guidelines [15].…”

Introduction: The purpose of this study was to compare diagnostic accuracy of a prostate multiparametric magnetic resonance imaging (mpMRI) protocol for detection of prostate cancer between images acquired with and without en-dorectal coil (ERC). Materials: This study was approved by the regional ethics committee. Between 2014 and 2015, 33 patients (median age 51.3 years; range 42.1-77.3 years) who underwent prostate-MRI at 3T scanners at 2 different institutions, acquired with (mpMRI_ERC) and without (mpMRI_PPA) ERC and who received radical prostatectomy, were included in this retrospective study. Two expert readers (R1, R2) attributed a PI-RADS version 2 score for the most suspect (i. e. index) lesion for mpMRI_PPA and mpMRI_ERC. Sensitivity and positive predictive value for detection of index lesions were assessed using 2 × 2 contingency tables. Differences between groups were tested using the McNemar test. Whole-mount histopathology served as reference standard. Results: On a quadrant-basis cumulative sensitivity ranged between 0.61-0.67 and 0.76-0.88 for mpMRI_PPA and mpMRI_ERC protocols, respectively (p > 0.05). Cumulative positive predictive value ranged between 0.80-0.81 and 0.89-0.91 for mpMRI_PPA and mpMRI_ERC protocols, respectively. The differences were not statistically significant for R1 (p = 0.267) or R2 (p = 0.508). Conclusion: Our results suggest that there may be no significant differences for detection of prostate cancer between images acquired with and without an ERC.

“…Patients should be instructed about the importance of not moving during image acquisition. An endorectal coil (ERC) is not an absolute requirement at either 1.5 T or 3 T anymore, but strongly recommended for imaging at 1.5 T (Beyersdorff et al 2003). 3 T MRI scanners and the associated higher signal-to-noise ratio (SNR) provide excellent image quality without ERCs, which in turn translates generally in better patient acceptance.…”

“…Although endorectal coil establishes higher image quality than pelvic coil due to the proximity of the coil to the prostate and higher signal to noise ratio but the accuracy rate for prostate cancer detection and staging range widely from 51% to 89% with endorectal coil alone. The best image quality achieves with using combination of endorectal and pelvic phased-array coils (19, 20). …”

Imaging studies play an important role in detection and management of prostate cancer and MRI especially with the use of endorectal coil because of high contrast resolution is recognized as the best imaging modality in evaluation of prostate cancer. Multiparametric MR study including T1 and T2 weighted images, diffusion weighted images, dynamic contrast study and MR spectroscopy is useful for detection and local staging of prostate cancer as well as posts treatment evaluation of patients either after surgery or radiation therapy for detection of local recurrence.
