超声造影与上腹部增强CT检查对肝血管瘤患者的诊断效能对比

Comparison on the diagnostic efficacy of contrast-enhanced ultrasound and enhanced CT of the upper abdomen in patients with hepatic hemangioma

目的对比超声造影(CEUS)与上腹部增强CT检查对肝血管瘤(HH)患者的诊断效能。方法200例HH患者,均给予CEUS检查和上腹部增强CT检查。以手术病理检查结果为金标准,比较不同检查方法对HH的诊断符合率、不同直径(≥4 cm、<4 cm)HH的检出率。结果CEUS对HH的诊断符合率为95.0%,增强CT对HH的诊断符合率为88.0%,比较差异无统计学意义(P>0.05)。两种检查方法对直径≥4 cm HH的检出率比较差异无统计学意义(P>0.05);CEUS对直径<4 cm HH的检出率为94.8%,高于增强CT的82.8%,差异具有统计学意义(P<0.05)。结论增强CT和CEUS检查均能有效检出HH,但对于直径小的病灶,CEUS更有优势。因此将增强CT和CEUS检查结合起来,能有效提高HH的诊断准确率,值得在临床推广应用。

Objective To compare the diagnostic efficacy of contrast-enhanced ultrasound(CEUS)and enhanced CT of the upper abdomen in patients with hepatic hemangioma(HH).Methods All 200 HH patients were examined by CEUS and enhanced CT of the upper abdomen.Using the results of surgical and pathological examination as the gold standard,the diagnostic coincidence rate of HH and the detection rate of HH with different diameters(≥4 cm,<4 cm)were compared among different examination methods.Results The diagnostic coincidence rate of CEUS for HH was 95.0%and that of enhanced CT for HH was 88.0%,and the difference was not statistically significant(P>0.05).There was no statistically significant difference in the detection rate of HH with a diameter of≥4 cm between the two examination methods(P>0.05).The detection rate of CEUS for diameter<4 cm HH was 94.8%,which was higher than 82.8%of contrast-enhanced CT,and the difference was statistically significant(P<0.05).Conclusion Both contrast-enhanced CT and CEUS can effectively detect HH,but CEUS is more advantageous for lesions with small diameters.Therefore,the combination of enhanced CT and CEUS examination can effectively improve the diagnostic accuracy of HH,which is worthy of clinical promotion and application.
