2010～2012年四川省人民医院儿科2148例MRI检查分析

Status Survey of MRI Examination in Children in Sichuan Provincial People's Hospital from 2010 to 2012

目的调查和分析四川省人民医院2010～2012年儿科门诊及住院患儿MRI检查情况,为儿童影像学检查的选择提供有利依据。方法收集该院PACS系统2010～2012年儿科门诊及住院患儿MRI检查的电子报告资料,并采用国际疾病分类(ICD-10)进行疾病分类,采用Excel 2003和SPSS 12.0软件对患儿基本情况、MRI检查部位、MRI检查阳性病例的系统疾病类别等进行统计分析。结果①2010～2012年四川省人民医院儿科行MRI检查的门诊及住院患儿共2 148例,检查人数逐年增加,男孩多于女孩,检查阳性率逐年略有下降;门诊患儿检查人数多于住院患儿,但检查阳性率低于住院患儿;②患儿MRI检查部位逐年增加,以单部位检查为主(占85%以上)。MRI检查部位以头部、头MRA、颈椎、膝关节、腰椎、垂体、胸椎、腹部为主,检查部位逐年多样化,检查新技术应用逐年增加;③MRI检查阳性病例按系统疾病分类可分为9类,占ICD-10标准分类的42.86%,主要以神经系统疾病、肌肉骨骼和结缔组织疾病为主。主要疾病类型总体较为稳定,但疾病类型中膝关节损伤、脑萎缩、软化、颅脑发育异常增幅较大。结论四川省人民医院2010～2012年儿科门诊及住院患儿MRI检查人数、检查部位逐年增多,MRI检查在头部、脊柱四肢关节及软组织部位应用较多,儿童MRI检出阳性疾病主要为神经系统疾病、肌肉骨骼和结缔组织疾病。

Objective To investigate the situation of MRI examination in children in outpatient and inpatient de- partments of the Sichuan Provincial People＇s Hospital from 2010 to 2012, so as to provide favourable basis for the choice of imaging examination in children. Methods The materials of electronic reports of MRI examination in paediatric inpa- tient and outpatient departments from 2010 to 2012 were collected, categorized, and analyzed. Results a） 2 148 children underwent M RI examination in the Sichuan Provincial People＇s Hospital from 2010 to 2012. 3he total number of patients increased with year. Boys were more than girls. The positive incidence was slightly decreased. The number of outpatients was more than inpatients, but the positive incidence was lower in outpatients, b） The total numbers of examination posi- tion were increased with year and the number of single position examination was the most （accounted for than 85% of the total numbers）. The main examination positions included： head, MRA of the head, cervical column, knees, lumbar column, pituitary gland, thoracic column, and abdomen. The examination positions diversified gradually. The application of examination technique also increased gradually, c） The systemic disease spectrum of positive cases in MRI examination included 9 categories, which accounted for 42.86% of ICD-10. The nervous systematic disease, muscle, skeleton and con- nective tissue disease were the categories. The major disease types were stable during the recent 3 years. The increase was obvious in injuries of the knees, malacosis and atrophy of the brain, the deformity of the brain. Conclusion The total numbers of the patients and positions examined increased gradually with year in the Sichuan Provincial People＇s Hospital from 2010 to 2012. The applications of MRI in the head, limbs and joints, and soft tissues were more extensive. Children diagnosed as positive results had diseases of the central nervous system, limbs and joints, and connective tissue disease.
