The laminae arrangement within the left ventricle is believed to strongly determine the tissue shearing that allows the muscle contraction. In this work we demonstrate that in-vivo DTI is capable of detecting discrepancies between diastolic and systolic laminae organization that agrees with previously reported histological studies.
