Typical raw image quality. Images are shown without averaging at b = 450smm−2 obtained from both of the sequences at each of the three cardiac phases in the cardiac cycle tested. Each of the images was acquired with diffusion encoding in the same direction and the images are windowed based on equalising the mean image intensity in an ROI drawn in septum. The bright left ventricular (LV) blood pool is evident in the M2-SE images due to the incomplete nulling of the blood signal. There is a higher signal intensity in the septal wall than in the lateral wall in images from both sequence. This is likely to be the result of spatial variation in the in-plane excitation profile (phase encode direction is horizontal in the image plane shown), variations in parallel imaging g-factor and uncorrected components of spatial variation in coil sensitivity
