The feasibility of undersampling 3D whole heart CSPAMM tagging data using k-t PCA was investigated. In computer simulations it is shown that acceleration factors up to 3.7 can be achieved without compromising the accuracy in determining motion parameters such as circumferential strain, circumferential shortening and rotation. This opens up the possibility to acquire 3D CSPAMM data in a single breathhold thereby eliminating the need for repetitive breathholding.
