Native (a) and post-contrast with the EQ-CMR technique (b) T1 maps in a patient with AL amyloidosis. A ROI is placed in the septum (white ROI) and in the blood (black ROI) in the native and post-contrast T1 maps. Native T1 value is increased (1,219 ms; N, 1,031 ± 24) and post-contrast T1 time is shortened (481 ms). The two T1 maps values combined with 1-haematocrit blood correction enable the calculation of the ECV that is increased (68 %) in this patient. (Native blood T1, 1,121 ms; post-contrast blood T1, 541 ms; haematocrit, 48 %)
