“…PURPOSE: To explore the value of a new simple lyophilized kit for labeling PRGD(2) peptide ((18)F-ALF-NOTA-PRGD(2), denoted as (18)F-alfatide) in the determination of metabolic tumor volume (MTV) with micro-PET in lewis lung carcinoma (LLC) tumor-bearing C57BL/6 mice verified by pathologic examination and compared with those using (18)F-fluorodeoxyglucose (FDG) PET. …”

“…Moreover, the range of its values was higher on PSF(breast) images as compared to OSEM(breast), especially in small lesions (MTV < 3 ml). CONCLUSIONS: High-resolution breast PET acquisitions, applying both small-voxel matrix and PSF modelling, appeared to improve the characterisation of breast tumours. …”
