From: Hematocrit, iron and HDL-cholesterol explain 90% of variation in native blood T1
ShMOLLI T1 maps from 3 healthy volunteers with (top left, top right, bottom right) high, normal and low blood T1. Comparing high T1 case with low, in this case, both the Hct (37% vs 49%) and the iron were lower (13.2 μmol/L vs 32 μmol/L where normal is 6.6-26 μmol). Bottom right: example correlation, here Blood T1 by ShMOLLI and Hct (R2 0.53, p < 0.0001).
