目的 评价经脾门静脉造影CT（CTSP）在肝转移瘤诊断方面的应用价值。方法 利用全身CT扫描机，采用动态系列扫描程序对22例肝转移瘤患者进行CTSP检查，并与B超、CT平扫及CT增强扫描作对照。结果 B超、CT平扫及CT增强扫描CTSP对病变的总检出率分别为57.7％、60.4％和68.9％，91.7％；对小病变（直径小于或等于1cm）的检出率分别为32.7％、38.6％和48.3％，91.8％，CTSP与其他3种方法有显著性差异（P＜0.01(；对直径大于1 cm的病变，4种方法无统计学意义（P＞0.05）。结论 CTSP对肝内转移瘤病变的敏感度高，可提供精确清楚的病灶定位，是术前选择适宜手术对象的最佳方法之一。
Objective To evaluate the value of spleno-portal venography (CTSP) in the diagnosis of liver metastases. Methods Twenty-two patients with liver metastases underwent dynamic serial scans using a CT scanner. CTSP was performed in patients with liver metastases and was compared with B-scan, CT scan and CT scan. Results The overall detection rates of CTSP on CT scan and CT scan were 57.7%, 60.4% and 68.9%, 91.7% respectively. The detection rates of small lesions (diameter less than or equal to 1cm) were 32.7 %, 38.6% and 48.3%, 91.8%, respectively, there was a significant difference between the CTSP and other three methods (P <0.01, and for the diameter greater than 1 cm, the four methods were not statistically significant High sensitivity to intrahepatic metastases lesions, can provide accurate and clear focus of the lesion, preoperative selection of appropriate surgical objects, one of the best.
