Method for characterizing cardiac lesions and associated systems

A method for heart lesion characterization using images of a zone to be imaged comprising the heart of a patient, the heart comprising a myocardium delimiting a cavity of the heart, the images comprising:

• a black blood image generated from signals acquired during a black blood-late gadolinium enhancement magnetic resonance acquisition,
• a bright blood image generated from signals acquired during a bright blood-late gadolinium enhancement magnetic resonance acquisition, the bright blood acquisition being distinct from an inversion-recovery sequence,
• said method comprising:
• computer segmenting the bright blood image so as to generate positioning data of a set of at least one wall delimiting the myocardium,
• computer heart lesionally characterizing from the black blood image and positioning data, at least one wall of the set of at least one wall delimiting the myocardium, taken from the positioning data of the set of at least one wall delimiting the myocardium.
