摘　　要：目的探讨双膈顶中内侧段幕状改变形成与性别、年龄、体型及侧别等因素的相关性。方法回顾性分析住院患者的影像学资料,筛选出具备双膈顶或单膈顶中内侧段幕状改变的患者共573例,所有患者均进行过X线胸部正侧位检查,其中69例除具备X线胸部正侧位检查外,又同时进行多螺旋CT扫描,并制成了三维重建的SSD图像。在此组患者中就性别、年龄、体型及侧别等相关因素数据进行统计学分析,并列出图表。结果具备双膈顶中内侧段幕状改变入选的573例中,幕状改变出现率与瘦长体型密切相关,与年龄关系密切,30岁以下470例,占82.02%,差异有统计学意义(P<0.05)。幕状改变与年龄分布折线图中峰值在20岁左右,以18岁出现最多,66例,占11.52%,差异有统计学意义(P<0.05)。在侧别的出现率上,单独左侧膈顶出现率最高,共505例,占88.13%;双侧膈顶出现45例,占7.85%;单独右侧膈顶出现23例,占4.01%,差异均有统计学意义(P<0.05)。在性别上,男318例,女255例,男女之比为1∶0.80,差异无统计学意义。结论双膈顶中内侧段幕状改变,出现率与体型、年龄及侧别关系密切;与性别差别关系不大。Objective To explore the correlation between the formation of medial segment in double dia- phragmatic top curtain shape change and some factors such as gender, age, and side. Methods Hospitalized cases of imaging data were retrospectively analyzed, a total of 573 cases with double diaphragmatic top or single diaphragmatic top shape changes in the medial segment of the tent were collected. All cases had an X- ray chest in the positive side, 69 cases of all the cases had extra spiral CT scanning except X- ray examination and made the SSD images of 3 d reconstruction. In this group, statistical analysis was ued to analysis the gender, age, size, and other relative factors, and then listed a chart. Results The 573 cases who had double diaphragm top in the medial segment curtain shape changes, the aeeurance rate of curtain shape changes was closely related with the slender body and age. There had 470 eases under the age of 30, accounted for 82.02% （P〈0.05） ,there had statistical significance. Screen peak shape change and age distribution in the line chart in their late teens or early 20 s, and the most in 18, there were 66 cases, accounted for 11.52% （P〈0.05） ,there had statistical significance. Of the rate oeeured in the other side, the left phrenie alone appeared the highest rate, a total of 505 cases, accounted for 88.13%. There were 45 cases in bilateral diaphragmatic top, accounted for 7. 85%. There were 23 cases in separate right diaphragmatic top, accounted for 4. 01%, there had statistical significance （P〈0.05）. On gender, male had 318 cases while female had 255 cases, the ratio was 1：0. 80, there had no statistical significance. Conclusion Double diaphragm top in the medial segment curtain shape change, the relationship between the accurance rate and body time, age, size and gender are small.
