目的通过超声造影(CEUS)与增强CT(CECT)或增强MRI(CEMRI)比较,探讨CEUS在小肝癌诊断中的价值。方法比较36例经手术/穿刺病理证实的小肝癌患者(43个病灶)的常规超声、CEUS以及CECT或CEMRI不同诊断方法的准确性,并比较CEUS与CECT或CEMRI不同时期影像表现模式。结果常规超声、CEUS与CECT或CEMRI诊断小肝癌的准确率分别为69.87%(30/43)、93.0%(40/43)与95.3%(41/43),CEUS与CECT或CEMRI明显优于常规超声(P<0.05);CEUS与CECT或CEMRI不同时期影像表现模式比较,差异无统计学意义(P>0.05)。结论CEUS对小肝癌有较高的诊断率,与CECT或CEMRI相近;两者不同时期影像表现模式具有可比性,CEUS是诊断小肝癌的重要影像学检查方法。
Objective To investigate the value of CEUS in the diagnosis of small hepatocellular carcinoma by contrast-enhanced ultrasound (CEUS) and enhanced CT (CECT) or enhanced MRI (CEMRI). Methods The diagnostic accuracy of routine ultrasound, CEUS, CECT or CEMRI in 36 small hepatocellular carcinoma patients (43 lesions) proved by operation / biopsy was compared. The imaging performance of CEUS, CECT or CEMRI was compared with each other. Results The accuracy rates of CEUS, CECT and CEMRI in the diagnosis of small hepatocellular carcinoma were 69.87% (30/43), 93.0% (40/43) and 95.3% (41/43), respectively. CEUS, CECT or CEMRI were significantly better than those of conventional (P <0.05). There was no significant difference in CEUS and CECT or CEMRI images in different periods (P> 0.05). Conclusions CEUS has a high diagnostic rate for small hepatocellular carcinoma, which is similar to CECT or CEMRI. Comparing the imaging manifestations in different periods, CEUS is an important imaging diagnosis method for small hepatocellular carcinoma.
