ADC Can Reliably Distinguish Recurrent Rectal Cancer From Scar Tissue


Background: Rectal cancer is commonly evaluated by MRI including diffusion-weighted images. The use of apparent-diffusion coefficient (ADC) maps permits a quantifiable evaluation of the tumor, including prediction of its response to therapy. Determining recurrent tumor from scar tissue is often difficult on morphologic MR images. Objective: To determine if diffusion-weighted images can distinguish recurrent rectal cancer from scar tissue. Design: Retrospective study. Methods: 72 pa more...
