Virtual hysteroscopy: a new non invasive approach for the assessment of uterine cavity.

Endometrial pathology is frequent in premenopausal women and the diagnostic hysteroscopy is considered the gold standard for assessing endometrial cavity and congenital uterine anomalies. However it is an invasive and uncomfortable procedure. Saline contrast hysterosalgingography and hysterosalpingo-contrast sonography allow detailed assessment of the uterine cavity.

Ethnic variation and variability of fetal nasal bone length at 11-15 weeks of gestation in a Brazilian population: preliminary results.
