Abstract
Background In routine cardiac MRI (CMRI) practice, radiological technologists are expected to optimize and utilize EKGs in gating and physiological monitoring. Many cardiac sequences are critically dependent on heart rate and rhythm and EKG gating problems lead to poor or nondiagnostic images. The technologist’s syllabus does not routinely include formal EKG recognition or CMRI trouble-shooting techniques. Methods In this educational exhibit, we describe common EKG rhythms and discuss imaging parameter options for overcoming magneto-hemodynamic effects, dealing with high or low heart rates and abnormal rhythms. Results An image sequence/EKG rhythm quick algorithm is included for reference and will be the basis of the exhibit.
