Figure 4From: Aortic valve stenotic area calculation from phase contrast cardiovascular magnetic resonance: the importance of short echo timeThe range of image quality in cine images obtained for AVA planimetry, and the corresponding planimetry are illustrated. These range from good quality (A), to cases where images were sub-optimal due to poorly defined borders (B, C) or in-plane flow artefacts (D), to one case where planimetry was not considered possible (E).Back to article page
