Prenatal diagnosis by imaging methods
VLČEK, Martin
The bachelor degree thesis focuses on imaging methods in prenatal diagnostics. The theoretical part informs the readers about the current situation in this field, including invasive and noninvasive examination methods. The theoretical part is concluded with a chapter on prenatal detection of heart disease by means of screening examination of pregnant women. The objective of the thesis was to highlight the activities of a radiological assistant, to describe his/her activities during the use of various modalities and possibilities in diagnostics of congenital heart diseases, both prenatally and perinatally. One hypothesis was formulated, concerning the activity of a radiological assistant in diagnostics of congenital heart diseases during the prenatal period. The quantitative research was designed based on the number of examined fetuses and newborns in the teaching hospital (Fakultní nemocnice) in Motol and in the Center of Medical Genetics (Centrum lékařské genetiky s.r.o.) in České Budějovice in the course of 1 year. In 59 fetuses examined with magnetic resonance the following 3 congenital heart diseases were detected most frequently: 7 cases of agenesis of corpus callosum, 6 cases of ventriculomegalia and 7 cases of congenital cystic adenomatoid lung malformation. None of the examined mothers was diagnosed with placenta defects or pathological changes on the fetus heart. The formulated hypothesis has been confirmed. At present, congenital heart diseases are not routinely prenatally examined by means of magnetic resonance due to the too robust technology and insufficient quality of the imaging. The prominent role is still being played by ultrasonic examinations performed by gynecologists and obstetricians. The thesis and the research results may be used by cardiologists, gynecologists, obstetricians, as well as radiologists.
