摘要
目的 分析多普勒超声、增强CT(CECT)对肝硬化背景下≤3cm结节样病灶鉴别诊断价值。方法 回顾性分析86例肝硬化合并肝内结节样病灶患者的临床资料。比较不同检查对肝硬化背景下结节样病灶的检出情况,对比其诊断良、恶性结节病灶准确性、敏感性、特异性。结果 86例患者共96个结节病灶:恶性结节50个,良性结节46个。结节直径≤2cm者54个,2.1~3.0cm者42个。经多普勒超声检查,良性结节检出35个,恶性结节检出36个,对肝结节样病灶的诊断敏感性、特异性和准确性分别为72.00%、76.06%、73.96%。经CECT检查,良性结节检出41个,恶性结节检出48个;对肝结节样病灶的诊断敏感性、特异性和准确性分别为96.00%、89.13%、92.71%。CECT诊断肝结节样病灶的敏感性、准确性明显高于多普勒超声(P<0.05)。结论 CECT检查相对多普勒超声相比优势更为显著,诊断敏感性、准确性更高,可有效提高疾病鉴别能力。
Objective To analyze the value of Doppler ultrasound and contrast-enhanced CT(CECT) in the differential diagnosis of nodular lesions less than 3 cm under the background of liver cirrhosis. Methods The clinical data of 86 patients with cirrhosis and intrahepatic nodular lesions were analyzed retrospectively. The detection of nodular lesions under the background of liver cirrhosis was compared by different tests, and the accuracy, sensitivity and specificity in the diagnosis of benign and malignant nodular lesions were compared. Results There were 96 nodular lesions in 86 patients: 50 malignant nodules and 46 benign nodules. There were 54 nodules whose diameter was no more than 2 cm and 42 nodules whose diameter was 2.1~3.0 cm. Doppler ultrasound examination detected 35 benign nodules and 36 malignant nodules. The diagnostic sensitivity, specificity and accuracy for hepatic nodular lesion were 72.00%, 76.06% and 73.96%, respectively. 25 nodules were misdiagnosed, including 11 benign nodules and 14 malignant nodules. The diagnostic sensitivity, specificity and accuracy for hepatic nodular lesion were 96.00%, 89.13%, 92.71%. 6 nodules were misdiagnosed, including 4 benign nodules and 2 malignant nodules. 1 nodule was missed. The sensitivity and accuracy of CECT in the diagnosis of hepatic nodular lesions were significantly higher than those of Doppler ultrasound(P<0.05). Conclusion Compared with Doppler ultrasound, CECT examination has more obvious advantages, higher diagnostic sensitivity and accuracy, which can effectively improve the ability of disease identification and reduce the rate of misdiagnosis.
