The normal values and ranges of fetal intracranial structures were studied by high resolution transvaginal ultrasonic scan at 12, 13 and at 14 weeks' gestation. The data including measurements of crown rump length (CRL), bi-parietal diameter (BPD), head circumference (HC), hemispheric width (HW), lateral ventricle width (LVW), LVW/HW ratio, thalamus and cerebellum may be useful in determining deviations from the normal and also in expanding the range of prenatal diagnoses of fetal structural abnormalities in early pregnancy.
通过高分辨率经阴道超声扫描，在妊娠12周、13周和14周时研究了胎儿颅内结构的正常值和范围。包括头臀长（CRL）、双顶径（BPD）、头围（HC）、半球宽度（HW）、侧脑室宽度（LVW）、LVW/HW比值、丘脑和小脑测量在内的数据，可能有助于确定与正常情况的偏差，也有助于扩大早孕期胎儿结构异常的产前诊断范围。
