Sonography in cervical insufficiency:

This ultrasound image of gravid uterus shows the cervix measuring 1.1 cms. in length (shortening) with dilatation (3mm.) of the internal os. The image was taken using the transvaginal route, using a Toshiba Xario ultrasound system. Dilatation with effacement of the cervix are diagnostic of cervical insufficiency. The management in this case would mean cervical cerclage.

From the virtual 3D image to real life size models of the fetus

Just saw this interesting link: http://www.dailymail.co.uk/sciencetech/article-1195703/The-stunning-new-technology-allows-parents-hold-life-size-model-unborn-child.html
It seems a PhD student Jorge Lopes has found a method to create 3D life size plaster models of the fetus as seen on 3D Ultrasound and MRI imaging. The replicas can help the mother identify and bond more intensely with the baby in the womb. Maybe, in the not too distant future, we may see Obstetricians and radiologists prepare plaster models, as easily as thermal print images of the fetus!!
