Abstract

Functional imaging of small animals,such as mice and rats,using high-performance positron emission tomography (PET)and single-photon emission tomography (SPECT), is becoming a valuable tool for studying animal models of human disease. The possibility to use either PET or SPECT allows the scientist to exploit the advantages of both techniques, e.g., the wide range of easily accessible single-photon radiotracers for SPECT and the exquisite performance of PET. The combination of PET and SPECT techniques for small-animal studies could offer the unique possibility of developing new and interesting protocols for the investigation of many biological phenomena more effectively than with PET or SPECT modality alone.

Abstract

At the Department of Physics of the University of Pisa, Italy, a new and fully engineered version of the YAP-(S)PET small animal scanner has been recently installed. The new YAP-(S)PET is able to perform both PET and SPECT studies on small animals. The scanner is made up of four heads: each one is composed of a 4 × 4 cm² YAIO3:Ce (or YAP:Ce) matrix of 20 × 20 elements, 2 × 2 × 25 mm³ each, coupled to a Position Sensitive Photomultiplier (PS-PMT) (Hamamatsu R2486). The four modules are positioned on a rotating gantry. The switching to the SPECT modality is easily made by mounting a high resolution parallel hole (0.6 mm ⊘, 0.15 mm septum) lead collimator in front of each crystal. This paper reports the performance of the system in terms of absolute sensitivity and spatial resolution for both PET and SPECT modalities. The scatter fraction and noise-equivalent count rate (NEC) for a mouse phantom for different energy windows have been measured in PET modality. Images of phantoms and animals are also presented.
