The combination of anatomic and flow data from MRI provides a highly sensitive and specific non-invasive method to predict clinically significant aortic coarctation gradients.
Nielsen et al. (2005) conducted an observational in Aortic coarctation (n=41). Magnetic Resonance Imaging (MRI) vs. Cardiac catheterization was evaluated on Peak coarctation gradient >= 20 mm Hg by catheterization (OR 1.71, p=0.005). The combination of MRI-derived anatomic and flow data predicted a catheterization gradient ≥20 mm Hg with 95% sensitivity, 82% specificity, and an AUC of 0.938.
