Multiparametric MRI of the prostate has become a reliable technique for the detection, staging and characterization of prostate cancer (PCa). So far, however, there is no consensus about the minimal MR equipment needed for improved prostate diagnostics. In particular, the use of an endorectal coil (ERC) at higher field strengths is discussed controversially. This work demonstrates that the additional use of an ERC at 3 T improves image quality measures related to the localization and staging of PCa. The use of an ERC intraindividually improves the detection of cancer-suspicious lesions (PI-RADS≥3) and the tumor detection rate per patient.
