PURPOSE: Some patients cannot remain immobile for a long duration of 60 min, which is generally applied in the case of a 2-deoxy-2-[(18)F]fluoro-D: -glucose ([(18)F]FDG) dynamic positron emission tomography (PET) scan. We investigated the change of the parametric values when the time duration of PET data was shortened. PROCEDURES: Eight normal subjects and four subjects with brain glioma were studied. The rate values of K (1), k (2), k (3), and K (i) parametric images were computed by changing the time duration from 20 to 60 min, and changes of those parametric values were compared. RESULTS: The change was 20-30% and 3-5% for k (3) and K (i), respectively, when the scan time was shortened from 60 to 40 min. The ratios of normal and disease regions in k (3) and K (i) values were similar, and contrasts of those images were not changed when the scan time was shortened to 40 min. CONCLUSIONS: These results demonstrate that the short time duration of [(18)F]FDG PET examination can provide an acceptable estimation of parametric k (3) and K (i) images. |
