目的探究和分析超声造影对肝硬化合并小肝癌的早期诊断价值。方法选择40例经手术病理检查确诊的肝硬化合并小肝癌患者为研究对象,病灶共有45个,病灶大小均<3 cm。记录和分析病灶造影的增强模式,并予以评分。造影前后15 d内对所有患者实施增强CT,并对结果进行比较。结果超声造影结果显示,中低-低分化癌共36个,造影后动脉期快速增强,实质期则快速退出;高分化癌有5个,造影后动脉期快速增强,实质期则缓慢退出;透明细胞癌共4个,3个门脉期轻度增强,实质期则缓慢退出,1个门脉期快速增强,实质期则快速退出。造影前多数声像缺乏典型性,仅有20个病灶确诊。造影后共有14个病灶超声诊断评分为2~4分,15个病灶分值提高。结论采用超声造影对小病灶进行检查,能够有效提高肝肿瘤的早期诊断率,对医师的诊治提供了有效依据,值得普及。
Objective To explore and analyze the value of contrast-enhanced ultrasound in the early diagnosis of cirrhosis with small hepatocellular carcinoma. Methods Forty patients with hepatocirrhosis and small hepatocellular carcinoma diagnosed by pathological examination were selected as research object. There were 45 lesions and the size of lesions were less than 3 cm. Record and analyze lesion contrast enhancement patterns and score them. All patients underwent enhanced CT within 15 days before and after contrast and the results were compared. Results The results of contrast-enhanced ultrasound showed that there were 36 low-moderately-poorly differentiated cancers, and the arterial phase increased rapidly after contrast and rapidly exited during the parenchymal phase. There were 5 well-differentiated cancers, the arterial phase increased rapidly after contrast and retreated slowly in real time. A total of 4 cell carcinoma, portal vein mild enhancement in 3, the real exit slowly, a rapid increase in the portal phase, the rapid withdrawal of the substantive period. Most of the anterior contrast imaging lack of typical, only 20 lesions confirmed. A total of 14 lesions after ultrasound imaging diagnostic score of 2 to 4 points, 15 lesions score increased. Conclusions Ultrasound imaging of small lesions can effectively improve the early diagnosis of liver tumors and provide an effective basis for the diagnosis and treatment of the patients, which is worth popularizing.
