摘　　要：目的旨在探讨64排螺旋CT图像后处理技术对膀胱癌的诊断价值。方法选取2017年1月-2018年5月我院收治膀胱癌患者54例,患者均进行了CT平扫及后处理技术检查,收集患者影像学资料,总结患者CT平扫及后处理技术中病灶的图像表现情况,以病理性检查结果为“金标准”,计算CT平扫及后处理技术诊断膀胱癌敏感度及特异度。结果CT平扫诊断膀胱癌的特异度及敏感度分别为87.03%、85.18%,CT后处理技术诊断膀胱癌的特异度及敏感度分别为98.14%、96.29%,CT后处理技术诊断膀胱癌特异度及敏感度明显高于CT平扫,差异具有统计学意义(χ^2分别为4.860、3.967,P<0.05);26例患者病灶位于膀胱三角区及后壁,膀胱侧壁者16例,前壁及顶壁者12例;外观形态:病灶大小约为0.56~10.56cm,平均直径(3.05±1.15)cm,多数患者病呈现“菜花状”,病灶表面凹凸不平,29例患者病灶侵入肌层;3例病灶表现为乳头状结节,粘膜层出现侵犯情况;CT平扫多数患者病灶部位密度与正常膀胱相近,密度均匀,仅仅9例患者CT平扫图像中可见病灶表面钙化灶。VR膀胱三维图像可以直观显示膀胱立体图像,从不同角度中均可观察到膀胱内突入的菜花状或乳头状肿块,患者肿块表面不光整,16例患者肿块呈现分叶状,在基底部可见局部膀胱壁增厚。结论64排螺旋CT图像后处理技术诊断膀胱癌敏感度、特异度高。Objective To explore the value of post-processing technique of 64-slice spiral CT in the diagnosis of bladder cancer.Methods 54 cases of bladder cancer admitted to our hospital from January 2017 to May 2018 were selected.All the patients underwent CT non-enhanced scanning and postprocessing techniques,collected the imaging data of the patients,summarized the images of lesions in the CT non-enhanced scanning and postprocessing techniques,and calculated the sensitivity and specificity of CT nonenhanced scanning and postprocessing techniques in the diagnosis of bladder cancer with the pathological examination results as the"gold standard".Results The specificity and sensitivity of CT non-enhanced scanning in the diagnosis of bladder cancer were 87.03%and 85.18%,respectively.The specificity and sensitivity of CT post-treatment in the diagnosis of bladder cancer were 98.14%and 96.29%,respectively.The specificity and sensitivity of bladder cancer diagnosed by CT post-treatment technology were significantly higher than that by CT plain scanning,and the difference had statistical significance(χ^2 was 4.860,3.967,P<0.05).The lesions were located in the trigonal region and posterior wall of the bladder in 26 patients,16 in the lateral wall of the bladder,and 12 in the anterior wall and parietal wall.Appearance morphology:the lesion size was about 0.56~10.56cm,with an average diameter(3.05±1.15)cm.Most patients presented"cauliflower-like"disease,with uneven surface of the lesion,and the invasion of muscle layer in 29 patients.The lesions were papillary nodules and the mucosal layer was invaded in 3 cases.The density of lesions was similar to that of normal bladder in most patients with CT non-enhanced scanning,and the density was uniform.The three-dimensional images of VR bladder can directly display the three-dimensional images of the bladder.Cauliflower-like or papillary masses protruding from different angles can be observed in the bladder.The tumor surface of the patient is not only whole,16 patients presented a lobul
