Accurate delineation of tumor extent and early assessment of response to treatment are open challenges in imaging evaluation of colorectal tumors. Quantitative imaging methods as relaxometry have been explored to fulfill this unmet need, but not adopted in clinical practice due to long acquisition time. In this feasibility study, we examined the relaxation time of rectal tumors, mesorectum and rectal wall using magnetic resonance fingerprinting (MRF)
