Figure 1From: Temporal stability of gel relaxation-time phantoms for quality control of T1 and extracellular volume fraction measurementsT1 and T2 maps (B&D) generated from eight 11-cycle MOLLI images (A) and multiple TE spin-echo images (C). Two bottles of each tissue phantom were made because larger volumes of NiCl2-agarose gels improve composition accuracy. The bottles were averaged for T1 and T2 measurements.Back to article page
