目的 :评价不同扫描方式影响螺旋CT血管造影 (SCTA)显示肝内血管的能力。方法 :对 92例患者作SCTA ,在快速注射对比剂 (3～ 4ml/s)后 ,对 5 2例患者从肝角向肝顶扫描 ,对 40例患者从肝顶向肝角扫描 ,经最大强度投影(MIP)法重建肝血管影像。结果 :从头侧向足侧扫描 ,门静脉显示较好 ,但肝静脉显示差。从足侧向头侧扫描 ,门静脉、肝静脉显示均较好。结论 :从足侧向头侧的扫描方式可作为肝血管SCTA常规检查的补充 ,有助于提高肝静脉的显示率
OBJECTIVE: To evaluate the ability of different scanning methods to affect intrahepatic vessels by spiral CT angiography (SCTA). Methods: Ninety-two patients underwent SCTA. Fifty-two patients were scanned from hepatic angle to the top of the liver after fast contrast injection (3-4ml / s). Forty patients were scanned from the top of the liver to the hepatic horn. Intensity projection (MIP) reconstruction of hepatic vascular images. Results: From the head to the foot side of the scan, the portal vein showed better, but the hepatic veins showed poor. From the foot side to the head side scan, portal vein, hepatic vein showed better. Conclusion: Scanning from the foot side to the head side can be used as a routine examination of hepatic vascular SCTA, which can help improve the rate of hepatic vein display
