We utilized AC-iTIP and combined it with a proposed correction method to achieve robust quantification of T1rho.
Figure 3. a) A raw image acquired using AC-iTIP at TSL 0
ms. b) The fitting results from the selected ROI in a). c) The ground-truth T1rho
map acquired. d) and e) show the T1rho map before and after correction,
respectively. f) compares the T1rho values in c)-e). Blue, red and yellows bars
represent c), d) and e), respectively.
Figure 4. a)-c) and d)-e) show B1 and B0 field maps from three different scans. g)-i) and j)-l) show the T1rho maps in vivo before and after correction. The cartilage and muscle are manually drawn for analysis.
