Develop rapid 3D PC technique for comprehensive cardiovascular imaging in CHD.
Materials and methods
PCVIPR data sets were successfully acquired in all subjects. MR angiograms were created using the average flow PCVIPR dataset to visualize cardiovascular structures. All anatomical structures visualized on CEMRA images were identified on PCVIPR images. On a case-by-case basis, additional hemodynamic information was obtained including visualization of flow patterns, flow quantification, and transstenotic pressure gradients. PCVIPR flow measurements were more accurate than the clinical routine targeted 2D PC measurements.
3D radially undersampled PC MRI has been shown to be a reliable and versatile tool for imaging patients with CHD. Combining shorter scan times and free breathing acquisition should make cardiac MRI a safer and more patient friendly examination in patients with CHD.
