PDFAbstract
Objective To explore the preoperative application of dynamic contrastenhanced magnetic resonance imaging (DCE-MRI) in patients with rectal cancer. Methods The scan images of MRI routine and DCE-MRI of 240 patients with rectal cancer treated in department of oncology at Xinyang Central Hospital from December 2015 to December 2017 were collected for retrospective analysis. The capacity transfer constant (Ktrans), rate constant (Kep) and EES volume ratio (Ve) were analyzed and compared with tumor pathological differentiation, Dukes stage, TNM stage and lymph node metastasis. Results Ktrans was increased significantly with the decreased tumor pathological differentiation, increased Dukes stage and TNM stage and lymph node metastasis (P<0.05). There was no significant difference in pathological differentiation, Dukes stage, TNM stage and lymph node metastasis between Kep and Ve (P>0.05). Conclusion DCE-MRI can better reflect the hemodynamics within tumor, and its Ktrans value is correlated with the pathological differentiation, Dukes stage, TNM stage and lymph node metastasis, and it has important application value for preoperative evaluation of rectal cancer.
