Absolute Event Rate: 1.6% vs 8.1%
A novel 3D wall thickness calculation algorithm significantly reduces overestimation errors compared to standard 2D planar methods in short-axis cardiac MRI.
Buller et al. (2002) studied Healthy individuals (left ventricle wall thickness measurement) (n=20). Three-dimensional wall thickness calculation algorithm vs. Planar (2D) method was evaluated on Measurement error at mid to low slices in software phantoms. A three-dimensional wall thickness calculation algorithm reduced measurement error in software phantoms to 1.6% at mid to low slices compared to 8.1% with the planar method.
