Small-Animal Imaging Using Clinical Positron Emission Tomography/Computed Tomography and Super-Resolution

Molecular Imaging, 2012
Considering the high cost of dedicated small-animal positron emission tomography/computed tomography (PET/CT), an acceptable alternative in many situations might be clinical PET/CT. However, spatial resolution and image quality are of concern.
