Motivation: The postoperative anastomotic fistula of rectal cancer is affected by radiation proctitis. Radiation proctitis is mainly evaluated by endoscopy, which is invasive and subjective.
Goal(s): To investigate the value of DCE-MRI parameters in diagnosising acute radiation-induced rectal injury.
Approach: In a retrospective analysis, DCE-MRI parameters of rectal wall in 49 patients after neoadjuvant chemoradiotherapy were measured and compared with the evaluation of Vienna endoscopy.
Results: Ktrans in patients with acute RRI was significantly lower compared to those without acute RRI, with a AUC of 0.80.
Impact: DCE-MRI is an appropriate non-invasive imaging technique for diagnosing acute RRI in patients with rectal cancer.
