Video Summary

In this video, Dr. Sharmila Dorbala, the director of nuclear cardiology at Brigham and Women's Hospital in Boston, discusses how to perform N13 ammonia perfusion studies in cardiac PET imaging. She covers the learning objectives, patient preparation, camera setup and quality control, the steps of a cardiac PET acquisition, and the reconstruction and display of images. She also discusses common artifacts and challenges in interpreting the images, including misregistrations, lung uptake, fixed defects, patient motion, and the quantification of myocardial blood flow. Dr. Dorbala provides examples of cases to illustrate these points, including cases with normal perfusion but low blood flow, reduced blood flow with normal perfusion, and challenging cases with multiple artifacts and abnormalities. She emphasizes the importance of careful image acquisition and interpretation, and advises referring to the ASNIC-PET guidelines for detailed protocols and guidelines.
