Abstract
In a method for quantitative detection of parameters in MRI, first and second spoiled gradient echo images and at least one multi-echo steady-state first/second magnetization image are acquired; based on the extended phase graph theory, signal equations are obtained corresponding to the first and second spoiled gradient echo images, the at least one multi-echo steady-state first magnetization image and the at least one multi-echo steady-state second magnetization image; based on the signal equations of the first and second spoiled gradient echo images, the signal equation of the at least one multi-echo steady-state first magnetization image and the signal equation of the at least one multi-echo steady-state second magnetization image, a spoiled gradient echo proton density map, a multi-echo steady-state proton density map, a longitudinal relaxation time map and a transverse relaxation time map of the target tissue are obtained.
