摘要
摘要目的比较分析超声造影与增强CT／MRI在诊断直径≤3cm肝脏占位病变中的价值。方法≤3cm的肝脏占位病灶40例患者分别进行超声造影、增强CT／MRI检查，比较超声造影与增强CT／MRI诊断≤3cm肝占位病变的准确性及两者之间的相关性。结果超声造影与增强CT／MRI诊断≤3cm的肝脏占位病灶的准确性分别为90．0％及82．5％，二者比较差异无统计学意义；但二者之间有较好的相关性（k=0．69）。对于病史不明确的单个占位病灶，超声造影可通过对增强时相的比较分析，鉴别其性质。结论超声造影及增强CT／MRI对≤3cm肝脏占位病变的诊断均有较好的临床实用价值。
Objective To evaluate the value of contrast - enhanced ultrasound （CEUS） and CT/MRI in diagnosis of ≤3cm focal liver lesions. Methods Forty patientes with ≤3 cm focal liver lesions were examined by CEUS and CT/MRI respectively. Then their accuracy and correlation were compared. Results The accuracy of CEUS and CT/MRI was 90.0% , 82.5% , respectively. There was no significant difference between CEUS and CT/MRI, while there was good correlation between the two methods （ k = 0.69 ）. In addition, the primary hepatic carcinoma and metastatic hepatic carcinoma can be differential diagnosed by CEUS, and analyzed by contrast - enhanced phase, the results was coincident to contrast - enhanced CT / MRI. Conclusion CEUS and CT / MRI has good clinical application value in diagnosis of ≤ 3 cm focal liver lesions.
