Figure 2From: Fetal blood flow measured using phase contrast MRI-comparison of image quality and flow volume at 1.5T with 3.0TComparison of PC CMR of the RPA at 1.5 T and 3.0 T. (a) Diagram of slice orientation through the fetal anatomy showing major vascular landmarks. (b) Magnitude and phase (velocity) data at 1.5 and 3.0 T, demonstrating superior SNR and anatomical visualization at 3.0 T. (c) Corresponding flow waveforms obtained from the RPA at 1.5 T (blue) and 3.0 T (red), and peak SNR (per pixel) for the RPA. RV = Right ventricle.Back to article page
