Video Summary

Jamie Bork, a medicine and radiology professor at the University of Virginia, discussed the technical advantages of Cardiac PET, focusing on its superior spatial and temporal resolution, high sensitivity, and reduced radiation burden compared to SPECT imaging. Cardiac PET applications include myocardial perfusion and function assessment, coronary calcium detection, and inflammation imaging. PET's hardware and radiotracers contribute to its resolution and sensitivity, enabling precise attenuation correction and blood flow quantification. The integration of CT enhances overall accuracy and specificity, aiding in conditions such as coronary artery disease. Bork highlighted different radiotracers, including Rubidium-82 and FDA-approved F18 fluorpyridaz, illustrating variations in their production and characteristics that influence spatial resolution and diagnostics. PET also facilitates advanced metabolic imaging for conditions like inflammation and cardiac amyloidosis by utilizing radiotracers like F18 fluorodeoxyglucose. These innovations extend PET's capabilities beyond perfusion to detect diverse cardiovascular conditions.
