摘要: Abstract Aim The aim of this study is to evaluate the accuracy preoperative magnetic resonance imaging (MRI) in prediction circumferential resection margin (CRM) and determine whether each different MRI scan plane provides an accurate CRM assessment. Method Fifty-seven consecutive patients with mid-rectal cancer were enrolled prospectively. measurement from according tumor location was compared on whole-mount sections definition threatened as 2mm distance. difference performance among sagittal, axial oblique MR images analyzed by using receiver operating characteristic (ROC) curves ( A z ). Results For anterior tumors n =17), planes 0.66, 0.83 0.79, respectively. lateral 0.53, 0.66 0.78, posterior =23), 0.76, 0.82 0.97, Conclusions CRM. There exist differences diagnostic within rectum.
