Basal short-axis slice selection for the left ventricle. Illustration of the basal plane selection following the SCMR guidelines [11]. “The left atrium can be identified when less than 50% of the blood volume is surrounded by myocardium and the blood volume cavity is seen to be expanding during systole”. The basal slice is the slice with more than 50% of myocardium muscle around the blood. In this example, slice 1 is in the left atria while slice 2 is the ventricle and can therefore be considered as the basal slice.
