Diffusion time dependent changes of ADC, FA, HA were analyzed in two fixed, excised porcine hearts using a stimulated echo approach at 7T with mixing times 50-1000ms. A standard SE-method was used as a reference and SNR differences were evaluated using the multiple image method. The data will allow better comparison of in-vivo measurements using SE- and STE-approaches. Ex-vivo measurements, which can provide high fidelity data at resolutions unachievable in-vivo, are usually performed on fixed tissue. We therefore assessed the impact of tissue fixation on T2 and T2* at 7T, which will allow optimization of future acquisition protocols.
