How to Perform a13N-NH3 Perfusion Study (Slides)

Pdf Summary

This document is part of a module on performing a 13N-NH3 cardiac PET perfusion study. The module covers various topics including acquiring and processing the study, preparing patients, optimizing injections, camera setup and quality control, and interpreting the results. It also discusses common artifacts and challenges that can occur during the study.<br /><br />Some key points from the document include:<br />- Patients should fast for 6 hours and avoid caffeine for 12 hours before the study.<br />- Camera setup and quality control are performed according to manufacturer recommendations.<br />- The acquisition process includes a scout or localizer scan, transmission scan, and emission scan. Specific density maps of the thorax are used to correct for photon attenuation.<br />- The study involves both rest and stress scans, with a prescan delay of 90-180 seconds for 13N-NH3.<br />- Motion artifacts can occur during the scan and can be corrected by deleting affected image frames and resuming without motion.<br />- Lung uptake of N-13 ammonia PET can cause artifacts, particularly in patients with heart failure or reduced left ventricular ejection fraction.<br />- The module includes case studies that illustrate various findings and challenges in interpreting the images.<br /><br />The document emphasizes the importance of careful preparation, acquisition, and interpretation to ensure accurate results and improve the accuracy of the test. It also references guidelines and resources for further information on performing cardiac PET studies.
