Magnetic Resonance Arterial Wall Imaging Methods that Compensate for Patient Aperiodic Intrinsic Cardiac, Chest Wall, and Blood Flow-Induced Motions

The technology includes MRI methods, systems, and software for reliably imaging vasculature and vascular wall thickness while compensating for aperiodic intrinsic motion of a patient during respiration.  To overcome the loss of the orthogonality due to uncompensated residual motions and after a lapse of time equal to the trigger delay commenced at the cardiac cycle, the system acquires multiple consecutive time-resolved images of the arterial wall.  The cine images are processed offline and a wall thickness measurement is produced.

The method improves arterial wall imaging by increasing the success rate of obtaining good and excellent quality images and imaging slice-vessel orthogonality. The method also provides more precise wall measurements and a more distinct difference between healthy subjects and patients.

The methodology and system can be applied to any commercially available MRI scanner.
