Assessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.
OBJECTIVE Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain.

Although these signs are useful methods in diagnosing of open spina bifida in ...

OBJECTIVE To measure changes in the posterior fossa of first-trimester fetuses with trisomy 18, trisomy 13 and triploidy. METHODS Brain stem (BS) diameter and BS to occipital bone (BSOB) diameter were measured in images of the midsagittal view of the face at 11(+0) to 13(+6) weeks from 45 trisomy 18, 21 trisomy 13 and 15 triploid fetuses and compared with values in 162 euploid fetuses.

متن کاملMaternal thyroid function at 11-13 weeks of gestation.
OBJECTIVE To establish normal ranges of maternal serum thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) at 11-13 weeks of gestation. METHODS Maternal serum concentrations of FT3, FT4, TSH, anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies were measured at 11-13 weeks. Normal ranges were constructed from the data of singleton pre...
