Technologist Track Session 02: CMR How To (2018)-Perfusion imaging

Video Transcription

Video Summary

The transcript explains first-pass cardiac perfusion CMR, mainly for detecting myocardial ischemia and assessing cardiac masses. It covers timing after contrast injection, spatial resolution needs, and common sequences such as turbo gradient echo, balanced SSFP, and EPI. It describes stress and rest protocols, emphasizing proper patient preparation, use of adenosine or dobutamine, avoiding caffeine/beta-blockers, and monitoring IV access and contrast timing. It also notes practical issues like dark rim artifact, signal-to-noise tradeoffs, and the need to choose imaging planes carefully for good coverage and diagnosis.
