摘要

Multiparametric magnetic resonance imaging (mpMRI) is accurate for detection of clinically significant (International Society of Urogenital Pathology [ISUP] grade group ≥2) prostate cancer (CS-PCa).1 Imaging quality is crucial for accurate mpMRI and should be compliant with Prostate Imaging and Data Reporting System (PI-RADS) specifications. 2,3 mpMRI can be performed without endorectal coil (ERC) at 3-Tesla (T),4,5 which improves patient tolerance, ease of use, and imaging artifact.5 A 1.5T mpMRI without ERC is more controversial. PI-RADS version 2 suggests imaging at 3T should be performed over 1.5T whenever possible and ERC may be indispensable at 1.5T;2 however, it is acknowledged that credible results have been obtained at 1.5T without ERC.6 There remains a subset of men in whom 3T imaging is contraindicated and where 1.5T imaging is required, namely those with uncleared (MRI-unsafe) medical devices for 3T. At institutions such as our own, that now perform mpMRI exclusively without ERC at 3T, accessibility and experience with ERC for 1.5T mpMRI is limited. This study evaluates the accuracy for detecting CS-PCa using 1.5T mpMRI without ERC in men with uncleared medical devices for 3T.
