目的：探讨64排螺旋CT肠系膜血管成像2种扫描。方法：动静脉双期扫描和动静脉平衡三期扫描对肠系膜血管的显示能力，比较2种扫描方法对临床疑似急性肠系膜上动脉栓塞筛查性诊断有无影响，以利于选择较少的曝光时间获得能明确诊断的图像篇幅。方法回顾性分析随机选择22例急性腹痛临床疑似肠系膜上动脉栓塞病例患者，行64排CT腹部血管成像检查，7例采用动静脉双期扫描，15例采用动静脉平衡三期扫描。评价双期扫描、三期扫描对肠系膜上动脉血管、病变的显示能力及各个扫描期征象特点。用配对X2检验曝光时间以及显示情况的不同。结果：对肠系膜血管采用2种不同扫描方法显示三级以上的分支比例均为100％，双期扫描诊断急性肠系膜上动脉栓塞2例，三期扫描诊断急性肠系膜上动脉栓塞3例，动静脉双期扫描和动静脉平衡三期扫描对患者接受曝光时间有统计学意义（P值＜0．05），对肠系膜血管显示状况的差异无统计学意义（P 值＞0．05）。结论：64排螺旋CT双期和三期扫描对急性肠系膜上动脉栓塞筛查性诊断无明显差异，选择动静脉双期扫描不影响筛查性诊断准确率，双期扫描有利于患者减少不必要的辐射剂量。
目的：探討64排螺鏇CT腸繫膜血管成像2種掃描。方法：動靜脈雙期掃描和動靜脈平衡三期掃描對腸繫膜血管的顯示能力，比較2種掃描方法對臨床疑似急性腸繫膜上動脈栓塞篩查性診斷有無影響，以利于選擇較少的曝光時間穫得能明確診斷的圖像篇幅。方法迴顧性分析隨機選擇22例急性腹痛臨床疑似腸繫膜上動脈栓塞病例患者，行64排CT腹部血管成像檢查，7例採用動靜脈雙期掃描，15例採用動靜脈平衡三期掃描。評價雙期掃描、三期掃描對腸繫膜上動脈血管、病變的顯示能力及各箇掃描期徵象特點。用配對X2檢驗曝光時間以及顯示情況的不同。結果：對腸繫膜血管採用2種不同掃描方法顯示三級以上的分支比例均為100％，雙期掃描診斷急性腸繫膜上動脈栓塞2例，三期掃描診斷急性腸繫膜上動脈栓塞3例，動靜脈雙期掃描和動靜脈平衡三期掃描對患者接受曝光時間有統計學意義（P值＜0．05），對腸繫膜血管顯示狀況的差異無統計學意義（P 值＞0．05）。結論：64排螺鏇CT雙期和三期掃描對急性腸繫膜上動脈栓塞篩查性診斷無明顯差異，選擇動靜脈雙期掃描不影響篩查性診斷準確率，雙期掃描有利于患者減少不必要的輻射劑量。

Objective:To investigate 64 row spiral CT imaging of mesenteric vessels two scanning meth-ods:arteriovenous dual phase scanning and arteriovenous balanced three phase scanning display ability of mesenteric vessels , compare two scanning methods for clinical screening diagnosis of suspected acute superior mesenteric artery embolism presence of influence , and to facilitate choice less exposure time can get a clear diagnosis of image space .Method:A retrospective analysis of 22 cases of acute abdominal pain in patients with clinically suspected cases superior mesenteric artery embolism , line 64 row CT abdominal vascular ima-ging , 7 patients with arteriovenous dual phase scanning , 15 patients with arteriovenous balanced three phase scanning .Stage of double scanning , three scan of the superior mesenteric artery , the lesions showed ability and each phase scan signs .With exposure time matching chi-square test and shows that the difference in sta-tus.The results of two kinds of scanning methods of mesenteric vascular branch showed rate was 100%, more than 3 dual phase scanning in the diagnosis of acute superior mesenteric artery embolism in 2 cases, the third phase of scanning in the diagnosis of acute superior mesenteric artery embolism (3 cases), arteriovenous du-al phase scanning and arteriovenous balanced three phase scanning for patients to accept exposure time had statistical significance (P <0.05), the mesenteric vascular shows that the difference in status has no statisti-cal significance ( P >0.05) .Conclusion:64 row spiral CT dual phase and three phase scan screening diag-nosis of acute superior mesenteric artery embolism has no obvious difference , choose arteriovenous dual phase scanning does not affect the screening diagnosis accuracy , patients with double scanning is helpful to reduce unnecessary radiation dose .
