多层螺旋CT血管造影对肠扭转的诊断价值

目的：探讨多层螺旋CT血管造影对肠扭转的诊断价值。方法：回顾性分析14例行腹部CT血管造影诊断肠扭转,并经手术证实病例资料。采用多平面重建MPR,容积再现VR,最大密度投影MIP等多种重建方式显示肠系膜血管。结果：14例均正确诊断,主要征象肠系膜血管的漩涡征（14例）,肠管的漩涡征（14例）,鸟喙征（10例）,肠壁水肿...

Diagnostic Value of Multi-Slice CT Angiography in the Intestine Volvulus

Objective： To discuss the value of multi-slice spiral CT angiography in diagnosing intestine volvulus. Methods： The CT materials of 14 cases with intestinal volvulus which were diagnosed by abdominal multi-spiral CT angiography and proved by operations were retrospectively analyzed. Images reconstruction including multiplanar reformation （MPR）, volume rendering （VR）, and intensity projection were adopted. Results： All the 14 cases were diagnosed accurately, and the main signs were ＂whirlpool＂ of vessels （14 cases）, ＂whirlpool＂ of intestine （14 cases）, ＂beak sign＂ （10 cases）, edema （8 cases）, and edema （7 cases）. Conclusion： Multislice spiral CT angiography can demonstrate the mesenteric vessels intuitively, clearly, and can show ＂＇whirlpool＂ of the superior mesenteric vein, which has important value to the diagnosis of the intestinal volvulus.
