Adenosine Stress (Tech)-Tips for Scanning Stress Patients

Video Transcription

Video Summary

The transcript describes a cardiac MRI stress perfusion workflow, focusing on adenosine-based scanning. It emphasizes careful patient preparation: stopping caffeine before the exam, explaining the procedure, obtaining consent, reviewing history, and cannulating the patient. The speaker explains practical setup details, including ECG lead placement, backup pulse gating when ECG is poor, adenosine dosing protocols, and adapting the scan for asthma, atrial fibrillation, or tachycardia. They also discuss image acquisition choices such as slice positioning, concatenations, and balancing field of view against artifacts. A major section covers common artifacts, including wraparound and Gibbs ring artifact, and how to reduce them. The talk concludes with key best practices: thorough preparation, correct slice planning, using four slices in two concatenations for fast or irregular heart rhythms, and having emergency evacuation protocols ready.
