MRI Findings in Anal Cancer
MRI is the gold standard for the diagnosis of anal cancer. [1] Common findings include:
- T1: primary and recurrent tumours have low to intermediate signal intensity in comparison to skeletal muscle
- T2: primary and recurrent tumours have high signal intensity in comparison to skeletal muscle
- Nodal metastases have similar signal intensity to the primary tumour
