摘　　要：目的 :评价双期螺旋CT经动脉门脉造影 (CTAP)能否降低非肿瘤性灌注缺损 (NPD)的发生率。方法 :36例经活检证实的原发性肝癌患者接受双期螺旋CTAP检查。在注入造影剂 30s后开始第 1期扫描 ,第 1期扫描结束后 10～ 15s开始第 2期扫描。两期扫描所见分别与碘油CT、肝动脉造影CT及重复性CT检查结果相联系。结果 :两期扫描的NPD发生率分别为 36 .1%和 8.3% (P <0 .0 5 )。结论 :双期螺旋CTAP能明显降低NPD的发生率。Objective:To evaluate whether the double phase spiral CT arterial portography(CTAP)reduce the rate of nontumorous perfusion(NPD).Methods:Thirty six patients with biopsy proved primary hepatocellular carcinoma underwent double phase spiral CTAP examination.Phase 1 started 30 seconds after the beginning of injection of contrast medium;Phase 2 started 10～15 seconds after the end of phase 1.Findings of double phase spiral CTAP images were correlated with iodized oil CT scan:spiral CT hepatic arteriography and follow up CT findings.Results:The rate of NPD was 36.1%in phase 1 and 8.3% in phase 2,respectively.There was significant difference between the phase 1 and phase 2 (<0.05)Conclusion:The double phase spiral CTAP can singificantly reduce the rate of NPD
