Tips and Tricks (Tech)-Tips on Image Aquisition

Video Transcription

Video Summary

The speaker shared practical tips for cardiac MRI image acquisition, emphasizing that MRI always involves trade-offs between spatial resolution, signal-to-noise, temporal resolution, and scan time. Key themes included obtaining robust ECG/BCG gating, adapting scanning strategies for arrhythmic patients, and adjusting acquisition windows, trigger methods, and parallel imaging to manage sinus tachycardia, bradycardia, ectopy, atrial fibrillation, and bigeminy. They also discussed black blood imaging timing, noting the importance of capturing the diastolic pause and that AF can make this difficult. For breathless patients, the speaker recommended inspiration breath-holds, shorter sequences, free-breathing options, and single-shot imaging. For unstable or time-limited patients, scan planning and prioritization were stressed. Finally, tips for imaging patients with cardiac devices included deep inspiration, shimming, bandwidth increases, and sequence adjustments to reduce artifact.
