摘　　要：目的观察多层螺旋CT(MSCT)后处理技术用于诊断耳硬化症的价值。方法回顾性收集47例(92耳)耳硬化症及65例(79耳)非耳硬化症听力障碍患者的临床资料及轴位平扫MSCT,对MSCT原始图像行后处理,包括镫骨、耳蜗多平面重组(MPR)及听骨链曲面重组(CPR),比较MSCT原始图像及其联合后处理技术诊断耳硬化症的效能。结果根据MSCT原始图像诊断66耳、联合后处理技术诊断89耳耳硬化症,二者敏感度分别为71.74%和96.74%,诊断准确率分别为81.29%和96.49%,后者均高于前者(P均<0.05);其特异度(92.41%vs.96.20%)差异无统计学意义(P>0.05)。结论联合后处理技术有助于提高MSCT诊断耳硬化症的敏感度和准确率。Objective To observe the value of multi-slice spiral CT(MSCT)post-processing technologies for diagnosing otosclerosis.Methods Clinical data and original axial plain MSCT of 47 patients with otosclerosis(92 ears)and 65 patients with non-otosclerosis hearing impairment(79 ears)were retrospectively enrolled.MSCT post-processing images,including multi-planar reformation(MPR)of stapes and cochleas and curved planar reformation(CPR)of ossicular chains were obtained.The diagnostic value of original MSCT images alone and raw data of MSCT combing with post-processing images for diagnosing otosclerosis were compared.Results Otosclerosis was correctly diagnosed in 66 ears according to original MSCT images alone,but in 89 ears combined with MSCT post-processing images.The sensitivity of original MSCT images alone and combined with MSCT post-processing images was 71.74%and 96.74%,respectively,and the diagnostic accuracy was 81.29%and 96.49%,respectively,those of the latter were both higher than of the former(both P<0.05),which had specificities being not significantly different(92.41%vs.96.20%,P>0.05).Conclusion Combining with post-processing technologies could increase the sensitivity and accuracy of MSCT for diagnosing otosclerosis.
