目的 探讨螺旋CT门静脉血管造影(spiral CT portolography,SCTP)临床应用价值。方法 89例肝脏疾病行SCTP检查及门静脉血管三维重建,三维重建方法包括MIP和SSD。结果 选择合适扫描检查技术可以获得较好的门静脉血管成像图像,SCTP可较好显示肝硬化门静脉血管大小形态变化、侧支循环血管开放情况及肝癌、肝血管瘤、肝囊肿、脂肪肝等肝内病变对门静脉推移,压迫和浸润情况。结论 SCTP是一种有效微创伤性门静脉血管成像技术,对了解肝内病变与门静脉的关系及门静脉大小形态改变有较大价值。
Objective To investigate the clinical value of spiral CT portography (SCTP). Methods Eighty-nine cases of liver disease underwent SCTP and portal vein three-dimensional reconstruction. Three-dimensional reconstruction methods included MIP and SSD. The results of choice of appropriate scanning technology can get better portal vein imaging images, SCTP can better show the morphological changes of portal vein blood vessels of cirrhosis, collateral circulation and liver cancer, hepatic hemangioma, hepatic cyst, fatty liver and other intrahepatic Pathological changes to the portal vein, oppression and infiltration. Conclusion SCTP is an effective minimally invasive portal vein angiography. It is of great value to understand the relationship between intrahepatic lesions and portal vein and the morphological changes of portal vein.
