Preoperative prediction of histological types and Ki-67 expression in rectal tumors using time-dependent diffusion MRI quantitative parameters
To investigate the clinical value of Time-dependent diffusion MRI (t d -dMRI) quantitative parameters in differentiating between rectal neuroendocrine neoplasms (rNEN) and rectal adenocarcinoma (RAC) and in distinguishing between high and low Ki-67 expression in RAC. This two-center study prospecti...
