3.0T MRI 动态增强与64层螺旋 CT 多期扫描诊断肝硬化背景下小肝癌的价值比较
Diagnostic performance of contrast-enhanced 3.0 T MRI and 64-multirow detector CT for small hepatocellular carcinomas in patients with liver cirrhosis
摘要
Abstract
Objective To evaluate the diagnostic performance of contrast-enhanced 3.0 T magnetic resonance imaging (MRI) and 64-multirow detector CT (64-MDCT) for small hepatocellular carcinoma (HCC) in patients with liver cirrho-sis.Methods Fifty-five cirrhotic patients with small HCCs (66 cancerous nodules ) were admitted to our hospital .All le-sions were quantitatively detected by contrast-enhanced 3.0 T MRI and 64-MDCT scanning.Two observers independently and randomly reviewed the 3.0 T MRI and 64-MDCT images on a lesion-by-lesion basis for the comparison of diagnostic value of the two methods.Results For each observer, the areas under the ROC curve were 0.893 ±0.013 and 0.859 ± 0.027 for 3.0 T MRI, respectively, as opposed to 0.657 ±0.034 and 0.679 ±0.026 for 64-MDCT, respectively.The differences between the two techniques were statistically significant for each observer (all P<0.01).The sensitivity, spe-cificity and negative predictive value of 3.0 T MRI for both observers were significantly higher than those of 64-MDCT ( all P<0.01).Conclusion The contrast-enhanced 3.0 T MRI shows a better diagnostic performance than that of 64-MDCT for the detection of small HCCs in patients with chronic liver disease .关键词
