Rectal cancer protocol (MRI)

MRI protocol for rectal cancer is a group of MRI sequences put together for imaging staging of primary tumors of the rectum. 

Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's and referrer's preference, institutional protocols, patient factors (e.g. allergy) and time constraints. 

Sequences

A good protocol for this purpose involves at least:

  • overviews
    • sagittal T2
    • axial T2
  • small FOV T2 through tumor 
    • axial - perpendicular to the plane of the part of the rectum containing the tumor
    • coronal - parallel to the plane of the part of the rectum containing the tumor
  • optional
    • diffusion-weighted imaging
