Anal Canal

  • Sofia Gourtsoyianni

Diffusion-weighted imaging (DWI) has been implemented in routine anal canal MRI protocols for the detection and delineation of squamous cell carcinoma of the anus (SCCA) and after definitive chemoradiotherapy for response assessment. In perianal disease, DWI is less established; however, it shows promise as an adjunctive sequence especially if intravenous contrast cannot be administered in centers that rely on post-contrast images to assess disease activity.
