PURPOSE For standardized interpretation of DCEMRI curves, calculation of contrast agent (CA) concentration from signal intensity over time is desired. Accurate measurement of tissue T1 before and after CA administration is thus necessary. Current T1 measurement methods are time-consuming. We propose the use of the ‘reference tissue’ method [Medved et al. JMRI 20(1):122, 2004] for fast T1 measurements concurrent with DCEMRI data acquisition, but with use of a reference phantom.
