Module 13a. Low Dose CT with Cardiac PET Perfusion-Low Dose CT with Cardiac PET Perfusion (Presentation)

Video Transcription

Video Summary

In this video, Dr. Randall Thompson, a cardiologist from Kansas City and a member of ASNIC, discusses the use of PET-CT imaging in cardiac perfusion studies. He explains the differences between CT and line source PET attenuation and the diagnostic information provided by the relevant attenuation maps. Dr. Thompson emphasizes the value of visually estimating coronary artery calcium scoring and highlights the limitations of low-dose CT attenuation maps. He provides examples of diagnostic information that can be obtained from PET source attenuation maps, such as lung masses and hiatal hernias, as well as the importance of inspecting the CT transmission scans for relevant cardiovascular diagnoses. Additionally, Dr. Thompson discusses the inclusion of coronary calcium scoring in myocardial perfusion imaging studies and its prognostic value. He recommends a systematic approach to reviewing the CT attenuation maps and suggests the inclusion of relevant findings in the study reports. Finally, Dr. Thompson advises on the need for proper training and guidelines in interpreting and reporting the CT attenuation maps in PET-CT studies.
