增强扫描在CT诊断周围型肺癌中的价值

Value of enhanced CT scan in dia gnosing peripheral lung cancer.

目的 比较平扫和增强扫描对周围型肺癌的诊断准确率 ,提高CT医生对孤立性肺结节常规行增强扫描的意识。方法 60例孤立性肺结节灶 ,分别行平扫和增强扫描 ,结节灶中央均加薄层扫描。结果 平扫诊断周围型肺癌误诊率 2 2 % ,漏诊率 32 % ;增强扫描诊断周围型肺癌误诊率 5 7% ,漏诊率 0 ;两者之间有显著差异 (P <0 .0 5)。

Objective To st udy the diagnostic accuracy of periphera l lung cancer with enhanced CT campared to normal CT scan.and urge the radiologs t to use enhanced CT scan routinely for solitary lung nodules.Methods 60 cases of solitary lung nodules were scanned by normal and enhanced CT with thine sliced scanning at centre of the lesions.Results The rate of misdiagn osing peripheral lung cancer was 22% wit h normal CT and 5.7% with enhanced one.T he rate of leakage was 32% for the upper and 0% for the latter with significant difference between the two(P<0.05)?Conclusion It is of importan t value of use the features of enhanced CT findings and dynamic enhancing curve to diagnose peripheral lung cancer.
