AI Technical Summary
Technical Problem
Existing cardiac MRI techniques struggle to accurately characterize myocardial lesions adjacent to blood chambers due to low contrast between healthy myocardium and blood, particularly in subendocardial scars, and difficulty distinguishing lesions from fatty tissues.
Method used
A device and method that combines black blood and white blood MRI sequences at different echo durations to generate fused images, using processing units to segment and characterize myocardial lesions and adipose tissue, enhancing contrast and precision.
Benefits of technology
Enables precise and automatic localization of myocardial lesions and adipose tissue, improving clinical observations by distinguishing between different tissue types with high accuracy and reliability.

Abstract
The invention relates to a device for imaging the heart of a patient, the heart comprising a myocardium, the device comprising at least one input interface, at least one processing unit and at least one output interface, the at least one processing unit being configured to implement, by means of a computer, a processing step comprising: - generating a first dark-blood image from first dark-blood signals; - generating a first bright-blood image from first bright-blood signals; - generating a second image of either the bright blood or dark blood type from signals of said type; and – based on the first dark-blood image, the first bright-blood image, and the second image of the aforementioned type, determining first data for locating a myocardial lesion and second data for locating adipose tissue.
