How to Perform an 18F FDG Infection/Inflammation Study (Slides)

Pdf Summary

Module 10 of the "How to Perform Cardiac PET" series focuses on performing and interpreting an 18F-FDG infection and inflammation study for cardiac PET imaging. The module discusses the roles of 18F-FDG PET/CT in imaging cardiac sarcoidosis and cardiac device infection.<br /><br />In cardiac sarcoidosis, 18F-FDG PET/CT can detect inflammatory granulomas and provide metabolic evidence of the disease's status. The module also highlights the key learning points, which include patient preparation with a high-fat, low-carbohydrate diet, and the importance of whole-body imaging rather than a limited chest scan.<br /><br />For cardiac device infection, early and accurate diagnosis is crucial. 18F-FDG PET/CT can help diagnose infection before structural damage occurs. The module recommends visual evaluation for differentiation between infection and inflammation, as well as considering non-attenuation corrected images and bacterial-specific tracers.<br /><br />The module also emphasizes the significance of 18F-FDG PET/CT in diagnosing prosthetic valve endocarditis and identifying extracardiac infection sources or septic emboli. Adding PET to the Modified Duke Criteria enhances the sensitivity of diagnosing endocarditis without compromising specificity.<br /><br />The module includes images demonstrating perfusion and metabolism patterns in cardiac sarcoidosis, as well as PET/CT images illustrating various infections and inflammations related to cardiac devices.<br /><br />Overall, this module provides detailed information on patient preparation, imaging acquisition and processing, and the interpretation of 18F-FDG PET/CT for infection and inflammation studies in cardiac PET.
