Due to the gross annular geometry of the left ventricle, a radial tagging sequence may be advantageous for measuring LV contraction and myocardial twist. Radial tagging, in general, requires shifting the patient table away from the iso-center of the main magnetic field to generate a tagging profile that is both sharp and centered at the middle of the LV cavity. In this study we show that >91% of patients can be acceptably imaged with the radial tagging sequence by retrospectively analyzing the short-axis slice position and orientation information from 75 patients in the Cardiac Atlas Project database.
