"A series of native T1 and postcontrast T1 images an acquired and co-registered. This can be done by an equilibrium infusion or after a bolus injection after waiting for a sufficient amount of time (15min) 1-5. T1 values can then be calculated pixel-wise from a signal intensity versus time curve fitting model 2. The administration of gadolinium leads to a shortening of the T1 value. Extracellular volume can be then calculated using the following formula 4:"

"Unlike native T1, extracellular volume seems not to be dependant on field strength, but similar to native T1 it varies between systole and diastole 2,4. There are only minor differences in regard to the myocardial region 6."
