正常女童卵巢磁共振多参数检测

目的:了解正常女童从新生儿至青春期内各个年龄段卵巢磁共振参数数值,为正常女童卵巢径线、体积、卵泡数目及最大卵泡直径提供参考值,提高对女童生殖系统疾病诊断.方法:搜集2016年12月-2017年12月新生儿至14岁行盆腔或骨盆、腰骶椎磁共振女童(排除生殖系统疾病),纳入扫描范围内至少有一侧卵巢结构显示病例共计491例,记...

The magnetic resonance imaging measurements of ovaries in healthy girls with multiple parameters

Objective:To investigate the value of ovarian magnetic resonance parameters in normal girls from newborn babies to adolescence,and to provide reference values for ovarian diameter,volume,number of follicles and maximum follicle diameter of normal girls,so as to improve the diagnosis of reproductive system diseases in girls.Methods:491 girls(excluding diseases of reproductive system or endocrine system)who underwent pelvic or pelvic and lumbosacral magnetic resonance imaging from December 2016 to December 2017 were collected.The data of ovarian length,anterior and posterior diameters,left and right diameters,ovarian volume,number of follicles and maximum follicular diameter measured by magnetic resonance imaging were recorded and analyzed statistically.Results:The ovarian diameter of normal girls increased slowly in the pre-puberty years.The ovarian length was less than 2.2cm,the anterior and posterior diameter was less than 1.4cm,the transverse diameter was less than 1.3cm,and the maximum follicular diameter was less than 0.7cm.After 8 years old,it showed an obvious increasing trend.There were some certain differences in ovarian diameter lines between pre-puberty and puberty,and differences were statistically significant,showing an obvious increasing trend.Conclusion:Magnetic resonance imaging can be used as a simple and reliable non-invasive evaluation to provide the reference value range of ovaries of healthy girls from newborn babies to adolescence,and to provide a reference basis for evaluating the development of girls and diagnosing other reproductive diseases.
