【摘要】 目的 探讨多排螺旋CT多模式重建在阑尾囊性病变中的应用。方法 经手术病理证实的阑尾囊性病变55例均经多排螺旋CT中下腹部平扫及增强,在图像后处理工作站对扫描数据进行多平面重建(MPR)、最大密度投影(MIP)、曲面重建(CPR)等多模式重建。结果 本组55例中,阑尾脓肿32例,阑尾黏液囊肿11例,阑尾黏腺囊腺瘤6例,阑尾黏腺囊腺癌4例,阑尾憩室1例,阑尾淋巴瘤1例。MPR对阑尾囊性病变及周边结构显示良好。MIP上良好显示病变血供来源,CPR可良好地显示囊性病变全貌。术前定位正确率达98.2%,病因诊断正确率达94.6%。结论 多排螺旋CT扫描结合各种重建模式能明显提高阑尾囊性病变的诊断正确率,应作为该组疾病的首选检查方法。更多还原

【Abstract】 Objective To evaluate the diagnostic value of MSCT the multi-mode reconstruction for appendix cystic lesions.Methods 55 cases with cystic lesions proved by surgery and pathology underwent multi-slice spiral plain and contrast-enhanced CT scans in the lower abdomen,the image data were post-processed at workstation including multi-planar reconstruction(MPR),maximum intensity projection(MIP),curved planar reconstruction(CPR) and other multi-mode reconstruction.Results Of 55 cases,there were appendix abscess in 32 cases,appendiceal mucocele in 11 cases,cystadenoma of the appendix sticky glands in 6 patients,the appendix sticky gland capsule adenocarcinoma in 4 cases,appendiceal diverticulum in 1 case and appendix lymphoma in 1.The cystic lesions of the appendix and the surrounding structure were showed well by MPR.The blood supply of lesions and detail of lesions were showed well by MIP and CPR,respectively.The preoperative localization rate and the diagnostic accurate rate were 98.2% and 94.6% by CT,respectively.Conclusion Multi-mode multi-slice spiral CT scan in combination with image reconstruction can improve the diagnostic rate of appendicular cystic lesions,which should be used as the first examination method for this disease.更多还原
