Comparison of CT and MRI in Diagnosis and Preoperative Staging of Rectal Cancer

目的比较CT和MRI在直肠癌诊断及术前分期中的价值。方法选择2017年4月—2018年4月我院收治的经过外科手术和病理诊断证实的直肠癌患者50例,均进行MRI与CT检查,将检查结果与病理检查结果相对比,并观察患者盆腔淋巴结以及肿瘤周围组织结构和直肠肿瘤情况;MRI根据直肠壁不同层的受侵犯情况作出相应评价,CT则按照直肠壁的光滑情况以及周围脂肪密度做出相关分析。结果 MRI诊断效果优于CT,差异具有统计学意义(P<0.05);MRI诊断敏感度高于CT诊断,两者差异具有统计学意义(P<0.05)。结论MRI检查相较于CT检查更能够准确的数据,提高临床疾病诊断的效率与准确性。

Objective To compare the value of CT and MRI in the diagnosis and preoperative staging of rectal cancer. Methods From April 2017to April 2018, 50 patients with rectal cancer confirmed by surgery and pathology were selected. MRI and CT examinations were performed. The results of the examination were compared with the results of pathological examination. The pelvic lymph nodes and the surrounding tissues and rectal tumors were also observed. MRI was evaluated according to the invasion of different layers of the rectal wall. CT was evaluated according to the smooth condition of the rectal wall and the density of the surrounding fat. Results MRI diagnosis was better than CT, and the difference was statistically significant（P 〈 0.05）. The diagnostic sensitivity of MRI was higher than that of CT, and the difference was statistically significant（P 〈0.05）. Conclusion MRI examination is more accurate than CT examination to improve the efficiency and accuracy of clinical diagnosis.
