1A Some of the critical design considerations. 1B Internal phantom structure showing tubes supported on a translucent unsaturated polyester and styrene resin base. 1C Axial trueFISP localiser image of T1MES. T1 and T2 values in prototypes mimic those of myocardium and blood pre and post gadolinium based contrast agents at 1.5T in green and 3T in red. Relaxometry scopes are 1 Short native myocardium, 2 Long native myocardium, 3 Native blood, 4 Short postGBCA myocardium, 5 Medium postGBCA myocardium, 6 Long postGBCA myocardium, 7 Short postGBCA blood, 8 Medium postGBCA blood, 9 Long postGBCA blood. 1D Typical T1 map of 3T prototype obtained by MOLLI using a bSSFP readout.
