PET-CT

PET-CT combines positron emission tomography (PET) detectors and computed tomography (CT) into one imaging system. PET requires the use of CT for image attenuation correction. The CT scanners that can be installed on these systems include 4-slice, up to workhorse 64-slice or higher systems. High slice CT is usually an option picked by  hospitals that plan to use the PET-CT scanner for standard CT only imaging exams as well. The CT scan anatomical imaging can be fused with the nuclear PET imaging to show anatomical landmarks. The CT component can also be used in cardiac PET to perform a coronary calcium scoring exam to offer a risk assessment for future heart attack risk.
