目的探讨多排螺旋CT(MDCT)的多种成像方式对胃肠源性急腹症的诊断应用价值。方法回顾性分析76例经手术或临床随访证实的胃肠源性急腹症患者的MDCT影像资料,采用后期处理技术,包括多平面重组(MPR)、曲面重组(CPR)、最大密度投影(MIP)、容积再现(VR)等建立多种不同成像,并与临床及病理结果对照分析。结果 MDCT诊断正确率为94.7%(72/76),其中55例肠梗阻误诊2例,8例消化道穿孔误诊1例,7例缺血性病变均诊断正确,6例炎症性病变误诊1例。结论 MDCT检查安全、简便,是临床诊断胃肠源性急腹症的可靠影像方法。
Objective To investigate the diagnostic value of multi-slice spiral CT (MDCT) in diagnosis of gastrointestinal-derived acute abdomen. Methods The data of MDCT in 76 patients with gastrointestinal acute abdomen confirmed by operation or clinical follow - up were retrospectively analyzed. The post - treatment techniques including multiplanar reorganization (MPR), surface reorganization (CPR), maximum density projection (MIP) , Volume rendering (VR) to establish a variety of different imaging, and with clinical and pathological results of controlled analysis. Results The diagnostic accuracy rate of MDCT was 94.7% (72/76). Among them, 55 cases of intestinal obstruction were misdiagnosed in 2 cases, 8 cases of digestive tract perforation were misdiagnosed in 1 case, 7 cases of ischemic lesions were diagnosed correctly, 6 cases of inflammatory lesions were misdiagnosed as one case . Conclusion MDCT examination is safe and easy, and it is a reliable method for clinical diagnosis of gastrointestinal acute abdomen.
