DETECTION OF MOTION ARTIFACTS IN DYNAMIC CONTRAST-ENHANCED BREAST MRI

摘要

A method for identifying motion artifacts in a dynamic contrast enhanced MRI includes receiving a dynamic contrast enhanced MRI including a patient's breast on which motion correction has been performed. One or more regions of suspicion are automatically identified within the breast based in the dynamic contrast enhanced MRI. The regions of suspicion are examined (S41). A measure of negative enhancement is calculated within a local neighborhood about each identified region of suspicion (S42). Each identified region of suspicion for which the calculated measure of negative enhancement is greater than a predetermined threshold is removed (S49).
