The restaging protocol is similar to the primary staging protocol, with the following exceptions:

• High-resolution T2-weighted techniques are recommended for optimal visualization of rectal and mesorectal anatomy and characterization of mesorectal lymph nodes.

• The recommended slice thickness is 3 mm and the in-plane resolution is 0.6 × 0.6 mm.².

• A strict axial T2W sequence is recommended to obtain a wide field of view and cover all relevant compartments for nodule staging.
