CARDIAC LATE GADOLINIUM ENHANCEMENT MRI FOR PATIENTS WITH IMPLANTED CARDIAC DEVICES

摘要

Disclosed herein are methods and systems for clinical practice of medical imaging on patients with metal-containing devices, such as implanted cardiac devices. In particular, Disclosed herein are methods and systems for improved late gadolinium enhancement (LGE) MRI for assessing myocardial viability for patients with implanted cardiac devices, i.e., cardiac pacemakers and implantable cardiac defibrillators.

主权项

1. An improved late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) sequence, wherein the LGE-MRI has a center modulation frequency, comprising:
shifting the center modulation frequency of the LGE-MRI sequence prior to collecting imaging information of the patient, wherein the shifting of center modulation frequency is achieved by using a wideband inversion pulse with a spectral bandwidth of 1 kHz or larger.
