How to Perform a13N-NH3 Perfusion Study (Slides)

Pdf Summary

This document is a module on how to perform a 13N-NH3 cardiac PET perfusion study. The module includes information on acquiring and processing the study, preparing patients, and optimizing 13N-NH3 injections. It also covers camera setup, quality control, and the protocols for the CT scan and blood flow measurement. The module discusses the interpretation of wall motion and blood flow, and provides case studies as examples.<br /><br />The module emphasizes the importance of patient preparation, such as fasting for 6 hours and avoiding caffeine and certain medications. It also highlights the need for camera setup and quality control as per manufacturer recommendations. The module describes the steps involved in acquiring the images, including scout scans, transmission scans, and emission scans. It also discusses the use of specific density maps to correct for photon attenuation.<br /><br />The module addresses various artifacts and pitfalls that may be encountered during the study. These include metallic objects in the heart causing emission activity signals, motion artifacts, increased lung uptake of N-13 ammonia PET, and fixed lateral wall perfusion defects. Solutions and recommendations are provided for dealing with these artifacts.<br /><br />Overall, the module provides comprehensive guidance on the acquisition, processing, interpretation, and quality control of 13N-NH3 cardiac PET perfusion studies. It emphasizes the importance of following standardized protocols and addressing potential artifacts to ensure accurate and reliable results.
