通过对400例死亡后胎儿进行系统性X 线检查的回顾性研究,作者指出,当诊断其它方面清楚,X 线检查不应常规进行。但是当有侏儒症或其它肢体异常和胎龄不清时,可考虑应用X 线检查。X 线检查可能更有助于遗传咨询。材料和方法400名胎儿,胎龄11～40周,均有完整的材料。X 线医师在阅片时,不知道胎儿临床情况。结果,X 线所见与临床和病理材料一致。通过比较临床资料与胎儿测量和成熟的组织学标准而估计胎龄。由于严重的母亲精神性疾病或急性胎儿疾病而引产的胎儿做对照。
By retrospectively conducting a systematic X-ray examination of 400 post-death fetuses, the authors state that X-ray examination should not be routinely performed when other aspects of diagnosis are clear. However, when dwarfism or other limb abnormalities and gestational age are not clear, consider the application of X-ray examination. X-ray examination may be more helpful for genetic counseling. Materials and methods 400 fetuses, gestational age 11 to 40 weeks, are complete materials. X-ray doctors reading the film, do not know the clinical situation of the fetus. Results, X-ray findings and clinical and pathological materials. Gestational age was estimated by comparing clinical data with fetal histories and maturation criteria. Control of fetuses induced by serious maternal mental illness or acute fetal disease.
