摘要:
Systems and methods for acquiring magnetic resonance images that accurately depict vascular calcifications, or other objects composed of magnetic susceptibility-shifted substances, in a subject are provided. The images are generally acquired using a pulse sequence that is designed to reduce physiological motion-induced artifacts and to mitigate chemical-shift artifacts from water-fat boundaries. Advantageously, the MRI technique described here suppresses chemical-shift artifacts without significantly reducing the signal intensity from fatty tissues, and thereby allows for more reliable visualization of vascular calcifications.
