The presurgical detection of extraprostatic extension (EPE) in prostate cancer is essential. Therefore, studies are carried out on possible indirect findings of EPE, especially in radiological terms. There are studies in the literature showing that there may be a relationship between tumor contact length (TCL) and EPE. It seems that there is no consensus yet on a threshold value for TCL. It is clear that more studies are needed on this topic. In addition, 3T MR device was used in most of these studies. On the other hand, MR images, including prostate multiparametric MR, are mostly obtained with 1.5T MR device in many centers. Studies on this topic designed with 1.5T MR device may be beneficial for more physicians.
