胸部X线透视检查在精神科体检中的应用价值

目的 探讨胸部X线透视检查(胸透)在精神科体检中阳性检出率及应用价值.方法 搜集22 683例住院精神病患者的胸透资料,按照年龄进行分组,计算阳性检出率,采用x2检验进行统计学处理.结果 精神病患者胸透阳性检出率为0.71％,40岁以上各年龄组各种疾病阳性检出率增加明显；40 ～49岁组与30～39岁组0.50％( 21/4174)比0.22％(9/4081),P＜0.05],50～59岁组与40～49岁组1.01％( 35/3473)比0.50％ (21/4174),P＜0.05],≤39岁与≥40岁组的阳性检出率差异具有统计学意义(P＜0.01).结论 胸透在精神科体检中阳性检出率低,且受X线照射剂量大,不应作为入院常规体检项目,应根据受检者的年龄、症状、既往病史等有选择地进行胸部X线摄影.

The chest X-ray in psychiatric screening

Objective To investigate the positive detection rate and the application value of chest X-ray in psychiatric screening.Methods Chest X-ray of 22 683 cases were applied for psychiatric screening and were divided into seven groups according to the age interval by decade,the positive detection rate was calculated with statistical analysis using x2 test.Results Chest X-ray positive detection rate was 0.71％ in psychiatric screening,the positive detection rate of various disease was significantly increased at the age groups above 40 years.There were significant statistical differences of the positive detection rate between the age groups 40-49 years and 30-39 years,age groups 50-59 years and 40-49 years,age groups ＜40 years and ≥40 years.Conclusions The positive detection rate of chest X-ray is low in psychiatric screening and the patients are irradiated by a large x-ray dosage.Chest X-ray should not be used as routine project in hospital and the chest radiography should be individualized according to the personal age,respiratory symptoms and previous medical history.
