摘要

目的：

探讨多层螺旋CT(multi-detector computed tomography，MDCT)增强扫描在结直肠癌术前分期中的临床应用价值。

方法：

回顾性分析本院30例经手术病理证实结直肠癌患者的CT图像，其中男性14例、女性16例。观察全腹部CT平扫+增强图像，并进行多平面重建(multi-planner reconstruction，MPR)，确定结直肠癌的CT分期，并与术后病理对照。

结果：

MDCT增强扫描对30例结直肠癌患者T分期的总体诊断准确率为73%，其中T1+T2、T3、T4分期的准确率分别为60%、78%、100%。CT增强扫描评价结直肠癌浆膜面受侵的灵敏度、特异度、阳性预测值、阴性预测值分别为80%、60%、80%、60%；CT增强扫描对结直肠癌N分期的诊断准确率为63%，其中N0、N1、N2分期的准确率分别为85%、14%、33%。CT增强扫描评价结直肠癌淋巴结转移的灵敏度、特异度分别为40%、85%，阳性预测值和阴性预测值分别为57%、73%。

结论：

MDCT对评价结直肠癌T分期、浆膜面受侵、N分期、淋巴结转移均有一定的价值，诊断结直肠癌浆膜面受侵的准确率较高，对术前分期有一定的指导意义。

Abstract

Objective:

To investigate the clinical value of enhanced 128-detector CT scan in the preoperative staging of colorectal cancer.

Methods:

CT data of 30 patients with pathologically proved colorectal cancer were retrospectively reviewed (14 male and 16 female). Enhanced CT with multi-planner reconstruction was done to get CT staging. CT staging and pathological staging were compared.

Results:

In the 30 patients

22 (73%) tumors were correctly T-staged by CT. In T staging

the accuracy was 60% for T1+T2

78% for T3

and 100% for T4. The

sensitivity

specificity

positive predictive value and negative predictive value of diagnosing the invasion of plasma membrane were 80%

60%

80% and 60%

respectively. Nineteen (63%) tumors were correctly N-staged by CT. In N staging

the accuracy was 85% for N0

14% for N1

and 33% for N2

respectively. The sensitivity

specificity

positive predictive value and negative predictive value of diagnosing the lymph node metastasis were 40%

85%

57%

73%

respectively.

Conclusion:

Enhanced CT has some value in diagnosing T-staging

invasion of plasma membrane

N-staging and lymph node metastasis. The diagnostic accuracy of invasion of plasma membrane by enhanced 128-detector CT scan is comparatively high.
