超声造影和CT/MRI增强检查在肝内局灶性病变诊断中的比较

Comparison of Ultrasound with CT/MRI Enhanced Scan in Diagnosis of Hepatic Focal Lesions

目的通过对比超声造影(CEUS)和增强CT/MRI(CECT/CEMRI)在肝内局灶性病变(FLL)的诊断,探讨CEUS的临床应用价值。方法利用74例接受了CEUS和CECT/CEMRI检查的病例,并与手术或穿刺活检病理结果比较,评估其诊断价值。结果 CEUS诊断准确率达94.6%,CECT/CEMRI诊断准确率达90.6%,CEUS和CECT/CEMRI对肝脏恶性肿瘤的诊断均有较高的准确率,对一些特殊肝脏肿瘤患者,联合检测可提高早期诊断的检出率。结论 CEUS对微小病灶及瘤内供血血管的显示优于增强CT和MRI。

Objective To investigate the clinical value of ultrasonid imaging by comparing the dianostic effect ofcontrast enhanced ultrasound （CEUS） and enhanced CT/MRI （CECT/CEMRI） in liver focal diseases （FLL）. Methods 74 cases of patients accepted CEUS and CECT/CEMRI inspection, and its results were corn- pared with surgery or biopsy pathol CEMRI were 94.6% and 90.6% ogical results. Results The diagnostic accuracy rates of CEUS and CECT! respectively. CEUS and CECT/CEMRI had higher accuracy for the diagno- sis of hepatic malignant tumors. Moreover, for some special liver cancer patients, joint detection could elevate the detection rate of early diagnosis. Conclusion Ultrasonic imaging for small lesions and tumor blood vessels is better than the enhancement CT and MRI.
