作者收集经病理组织学证实的6例肝血管肉瘤,其中男1例,女5例,年龄4～80岁。所有病例均作了螺旋CT平扫和双期增强扫描。对比剂注射剂量150ml,注射速率2.5～5.0ml/s。对比剂注射开始28s后作动脉期扫描,70s后作门脉期扫描。层厚7mm或10mm,螺距1.0～1.5,其中1例在对比剂注射4min后作了延迟扫描。由两位有经验的放射学专家对每例CT图像作了分析。确定各例病灶的数
The authors collected 6 cases of hepatic hemangiosarcoma confirmed by histopathology, including 1 male and 5 female, aged 4 to 80 years. Spiral CT plain scans and double-phase enhanced scans were performed in all cases. Contrast agent injection dose 150ml, injection rate of 2.5 ~ 5.0ml / s. The arterial phase scan was performed 28 seconds after the start of contrast injection and the portal phase scan was performed after 70 seconds. The layer thickness was 7mm or 10mm, and the pitch was 1.0 to 1.5. One of the cases was subjected to delayed scanning after the contrast agent was injected for 4 minutes. Each CT image was analyzed by two experienced radiologists. Determine the number of lesions in each case
