摘　　要：目的:研究多层螺旋CT后处理技术在急性阑尾炎中的应用。资料与方法:收集本院80例临床拟诊阑尾炎患者,术前均采用64排螺旋CT常规扫描,用adw4.6后处理工作站中后处理技术对图像重建,观察阑尾的形态、大小、位置及毗邻结构,评估其炎性浸润程度及范围,了解有无并发症。结果:其中76例阑尾不同程度增粗、水肿,周围少许渗出影;58例阑尾周围明显炎性渗出灶,相邻脂肪间隙模糊;18例阑尾内粪石嵌顿;16例阑尾周围脓肿形成;9例阑尾粪石嵌顿并脓肿形成;8例阑尾穿孔;3例阑尾脓肿并粘连性肠梗阻形成。3例右侧附件囊性病灶伴感染;1例低位肠梗阻。结论:对于急性阑尾炎患者的术前评估,多层螺旋CT的后处理技术是一种简单、快捷的方式,可多平面、多方位观察病灶,为临床诊断及鉴别诊断、制定手术方案及手术入路提供明确依据。Objective： To study the application of multi-slice spiral CT postprocessing technique in acute appendicitis. Materials and methods： The data of 80 patients with suspected appendicitis patients,preoperative using 64 slice spiral CT scan and postprocessing workstation with adw 4. 6 postprocessing technique on image reconstruction,observe the shape of the appendix,size,location and adjacent structures,evaluate the inflammatory infiltration degree and scope,understand the complication. Results： Among 76 cases of appendiceal thickening,edema of different degrees,around a little exudation; 58 patients with periappendicural obvious inflammatory exudation,adjacent fat space fuzzy; 18 cases of appendiceal fecalith in incarcerated; appendiceal abscess in 16 cases; 9 cases of appendicolith incarcerated and abscess formation; 8 cases of perforation of the railing; 3 cases of appendiceal abscess and intestinal obstruction due to adhesions formation. 3 cases of right adnexal cystic lesions with infection,1 cases with low intestinal obstruction. Conclusion： For the preoperative evaluation of patients with acute appendicitis,the post-processing technology of multi-slice spiral CT is a simple and quick way,which can observe the lesions in multi plane and multi directions,and provide a clear basis for clinical diagnosis and differential diagnosis,surgical planning and surgical approach.
