DWI plays an important role in the diagnosis of prostate cancer by detecting water molecules diffusion noninvasively, which reflects the microstructure of tumor tissue. However, only DWI might be limited by low sensitivity and specificity. T2 mapping imaging is a quantitative imaging technology to map the transverse relaxation time of tissues with good repeatability and stability. T2 mapping is also sensitive to tissue components (such as edema, fibrosis) without a contrast agent. This study aims to differentiate prostate cancers from hyperplasia by combining DWI and T2 mapping.
