Characterization of a whole body imaging technique for PET
- California Univ., Los Angeles, CA (USA). Div. of Nuclear Medicine
An investigation of rapid whole-body PET scanning was performed with a view towards its eventual use in screening for metastatic lesions with {sup 18}F-fluoride ion or {sup 18}F-fluorodeoxyglucose (FDG). This paper presents longitudinal images of the body were formed using three techniques: simple 2-D projection images were formed by resorting the sinogram data. The images were created for a set of angles covering a full 180{degrees} to facilitate viewing in a cine format. The effects of summing over a number of angles per view and filtering to reduce noise were investigated. Limited-angle backprojection images were formed using a small range of angles and no reconstruction filter. The resulting volume was then sliced coronally to give planar images as a function of depth. Coronal images were also obtained after reconstruction with a standard filtered backprojection technique, but with no attenuation correction. All three processes provided surprisingly good images of diagnostic quality, which were obtainable in practical scan times.
