Abstract:
1. A method for tissue property change detection in magnetic resonance (MR) guided intervention, the method comprising: acquiring, with an MR scanner, a MR intensity curve of tissue response over time in response to an inversion pulse; determining, with a processor, a first time before a zero crossing of the MR intensity curve and a second time after the zero crossing; identifying first locations from a comparison of an MR T1 map for the first time from before the MR guided intervention to an MR T1 map for the first time from after therapy in the MR guided intervention; identifying second locations from a comparison of an MR T1 map for the second time from before the MR guided intervention to an MR T1 map for the second time from after therapy in the MR guided intervention; locating tissue common to the first and second locations and with a reversed contrast for the first time as compared to the second time; and generating an image indicating the common tissue.
