摘要
目的 探讨编码谐波血管造影技术观察原发性肝癌血流灌注对肝恶性肿瘤定性诊断的临床应用价值。方法 经左前臂浅静脉注射氟碳造影剂 ,对 35例患者共 41个病灶进行编码谐波血管造影检查 ,观察肿块区域血管显像时间、血管分布及肿块组织血流灌注情况。所有病例造影前后表现均同步录像。结果 注射造影剂后 15~ 2 0s肿块开始显像 ,60~ 90s达到高峰 ,持续时间约 2 40~ 30 0s ,肿块比正常肝组织增强明显 ,表现为数量不等的条状血管自肿块边缘向中心分布 ,造影剂逐渐向肿块内弥散 ,形成“垂柳状”回声 ;肿块周围血管显影较正常肝组织早 ,表现为受压或成环状。结论 编码谐波血管造影能实时观察原发性肝癌的血流灌注 。
Objective Using coded harmonic angiography to observe hepatocellular carcinoma blood perfusion features,further assess this modality clinical value in qualitative diagnosis of liver malignant tumor.Methods Through left forearm vein bolus injection of fluorine-carbon contrast agent,35 patients with 41 hepatocellular carcinoma lesions were examined with coded harmonic angiography,intratumoral vessel enhanced time,vascularity,blood perfusion were observed.All patients were simultaneously videotaped before and after contrast.Results It was about 15~20 s after the injection of contrast agent when the enhancement of tumor had just commenced,peak time about 60~90 s and persistence time about 240~300 s.Lesions were more obviously enhanced than normal liver tissue,several tumor vascularity was displayed from border to center,contrast agent gradually centripetal filled-in,formed 'weeping-willow' echo.Pressed and rimlike peripheral vessel developments were earlier than normal liver tissue.Conclusions Coded harmonic angiography could real-timely display hepatocellular carcinoma blood perfusion,which has an important clinical value in qualitative diagnosis of liver malignant tumor.
