Fetal cardiovascular MRI was
possible with direct fetal cardiac gating by the DUS device. Benefits were shown
with promise in high-quality morphological and functional studies of the fetal heart
using routinely available imaging techniques, including cine, 4D flow and myocardial
mapping.
Figure 3. 4D flow exam of the fetal heart based on DUS fetal cardiac gating. Image examples with streamline visualization were selected from a case at 35 gestational weeks on 3.0T. Details see text.
DA = ductus arteriosus; PA = pulmonary artery; AoD = descending aorta; AoA = ascending aorta; RH = right heart; LH = left heart
Figure 2. Functional cine exams of the fetal
heart based on DUS fetal cardiac gating on 3.0T. (A) Selected images in 4-chamber view (4CH) at end
systole (ES) and end diastole (ED). (B) Selected images from three
adjacent short-axis slices (SAX) from ES to ED. Arrows indicated the fetal
heart at ES and ED.
