Prenatal neuroradiology: comparative radiological investigations of the embryonal and fetal brain.
In 400 embryos and fetuses of domestic animals and men, prenatal development of the cerebral vessels and ventricles was examined by postmortem arteriography, phlebography, microradiography, and ventriculography. In the ventricular system, qualitative and quantitative changes could be demonstrated and developmental diagrams of the growing ventricular spaces and angles were elaborated. The differentiation of the aortic arches into the major cranial arteries and the complex transformations of the cerebral venous system were documented by angiography within a period of gestation of 4 weeks up to term. Intrauterine angiography was also carried out in living fetuses of cats as preliminary studies of the development of cerebrovascular malformations.
