摘要
目的比较高分辨率MRI与Revolution CT增强扫描成像在直肠癌术前T分期诊断中的应用价值。方法我院接受治疗的74例经病理学确诊的直肠癌患者,术前均行高分辨率MRI与Revolution CT增强扫描成像检查。分析高分辨率MRI、Revolution CT增强扫描成像与病理诊断结果一致性,并比较高分辨率MRI与Revolution CT增强扫描成像对直肠癌术前T分期诊断符合率。结果 Kappa一致性检验显示,高分辨率MRI、Revolution CT增强扫描成像与病理诊断结果一致性均为优(Kappa值=0.888,0.820)。高分辨率MRI对直肠癌T分期总诊断符合率为93.2%,Revolution CT增强扫描成像对直肠癌T分期总诊断符合率为89.2%,组间差异无统计学意义(P> 0. 05)。结论高分辨率MRI、Revolution CT增强扫描成像与直肠癌术前T分期的病理诊断结果一致性均较好,均具有较高的诊断符合率,临床上可根据患者具体情况选择适宜的检查。
To compare the application values between high resolution MRI and revolution CT enhanced scan imaging in diagnosing T stages of rectal cancer before surgery.Seventy-four patients with rectal cancer confirmed by pathology in our hospital received examinations of high resolution MRI and revolution CT enhanced scan imaging.Consistency between pathologic results and high resolution MRI diagnosis as well as revolution CT enhanced scan imaging diagnosis were analyzed.At the same time,diagnostic accordance rates of T stages of cancer by high resolution MRI and revolution CT enhanced scan imaging were compared.Kappa consistency test showed that consistence between pathologic results and high resolution MRI and between pathologic results and revolution CT enhanced scan imaging were excellent(kappa value=0.888 and 0.820,respectively).The diagnostic accordance rate of high resolution MRI in diagnosing total T stages of rectal cancer before surgery was 93.2%,which was not significantly different from revolution CT enhanced scan imaging(89.2%,P>0.05).The consistency of high resolution MRI and revolution CT enhanced scan imaging with pathologic results in diagnosing T stages of rectal cancer are both excellent and both have high diagnostic accordance rates.Clinically,the two methods are suitable to be chosen according to patients specific situations.
