Anatomy and Slice Positioning (Tech)-Cardiac Anatomy with CMR

Video Transcription

Video Summary

The speaker, a UK-trained MRI professional at the University of Alberta Hospital, gives an interactive overview of cardiac anatomy and MRI planning. He reviews key structures in multiple planes, including the aorta, pulmonary arteries, atria, ventricles, valves, esophagus, coronary sinus, left atrial appendage, and bronchial anatomy. He emphasizes how to identify these on localizers and why accurate plane selection matters for cardiac imaging. He then explains standard cardiac MRI workflows for left ventricular function: obtaining three-plane localizers, then planning two-chamber, short-axis, four-chamber, three-chamber, LV outflow tract, and aortic valve cine images from orthogonal oblique planes. He highlights the value of these views for assessing ejection fraction, wall motion, perfusion, and coronary territories using the 17-segment model. Finally, he demonstrates Siemens’ “Cardiac Dot Engine,” showing how automated planning can rapidly generate a full LV study, while cautioning that technologists still need strong skills to maintain quality.
