Summary

Image misalignment in cardiac PET/CT scans causes false perfusion defects. Correcting this emission-transmission misalignment, especially with automated methods, improves accuracy in myocardial perfusion imaging.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
