PET imaging equipment |
Allegro whole-body PET scanner (Philips, Andover, MA, USA) obtained in a single FOV |
GE Advance PET scanner (GE Medical Systems, Milwaukee, WI, USA) in 3D modes with a 14.875-cm axial FOV obtained in a single FOV |
ECAT EXACT HR + scanner (Siemens-CTI, Knoxville, TN, USA) |
|
Reconstruction | Reconstructed by a 3-dimensional row-action maximum likelihood algorithm. Approximate spatial resolution was 6 mm. | Reconstructed to 35 transaxial images of 128 x 128 voxels by a back-projection algorithm using manufacturer-provided software correcting for attenuation, scatter, and dead time. Resolution was approximately 6 mm at full width at half maximum. | Not stated. | Not stated. |
FOV = field of view; MRI = magnetic resonance imaging; PET = positron emission tomography.
