Current state of hybrid imaging: attenuation correction and fusion

Excerpt

Hybrid positron emission tomography (PET) and computed tomography (CT) scanners were introduced in the late 1990s. Hybrid imagers were first used for oncology and were widely accepted for their unique ability to merge high-resolution anatomy with ¹⁸F-fluorodeoxyglucose (FDG) as a functional tumor agent. For cardiac applications, the CT data was useful only for attenuation correction, as the motion of the heart caused significant artifacts in the thoracic images of the mediastinum from the single slice CTs in these early scanners. Multidetector CT scanners for high-resolution cardiac imaging were integrated into hybrid systems starting in about 2002. For the first time it appeared that high-resolution cardiac anatomy would be easily correlated to myocardial perfusion images (MPI) using the same imager to acquire both images in a single scanning session. …
