title: [Volumetric growth of the gestational sac: reliability and clinical limits].
abstract: Thanks to the continuous progress of the ultrasound scanning in obstetrics it is now possible to see the gestation sac already the 5th week of the pregnancy. Aiming to simplify the methods, of the past, the authors suggest the utilisation of a very simple but at the same time extremely accurate methodology to measure the volume of the gestational sac. The comparison between the data which have been obtained with this study and those reported in the literature showed a substantial uniformity, though the results came from different procedure. At the end of the study, the uses of this parameter as well as its application in the solution of that particular problem in the ultrasound diagnosis which is the "blighted ovum" are explained.
