EVALUATION OF CARDIAC STRUCTURE

摘要

A method of optimizing scan parameters for LGE-MRI. At least one cardiac MRI Tl scout scan is performed by applying an inversion pulse every predetermined heart beat of a patient. An initial value of an inversion time TIinitial is determined by assessing a set of images generated from the scout scan. A first multiple of a duration between successive indicia of ventricular depolarization is selected, and a relaxation time TI is determined based on the initial value TIinitial and the first multiple of duration. An optimized inversion time TIoptimal for LGE-MRI is determined based on the relaxation time Tl and a second multiple of a duration between successive indicia of ventricular depolarization. A correction factor is determined based on the optimized inversion time TIoptimal from the initial value of the inversion time TIinitial.
