“…The 2D transmission data are directly used to correct the 2D emission data. Scatter correction is achieved by the convolution-subtraction method of Bergstrom (Bergstrom et al 1983). Twenty mCi (740 MBq) of [ 11 C] RAC was injected intravenously over 30-40 s. The total acquisition time of the scan was 90 min.…”

Attenua tion correction was performed using a projection thresh olding method similar to that of Bergstrom et al (1982), Owing to the limited number of counts available in the short scan periods.…”

Summary:Regional cerebral blood volume (CBV) can be calculated using data obtained during the kinetic analysis of 18F-labeled 2-fluoro-2-deoxY-D-glucose (FDG) uptake measured by positron emission tomography (PET). As a result the influence of vascular activity upon the determi nation of FDG rate constants can be minimized. The method is investigated by simulation experiments and by analysis of PET studies on seven older, healthy human volunteers aged 52-70 years. The accuracy of measured FDG rate constants kl' k2, and k3' obtained either by omitting the early portion of the uptake curve or by ex plicit inclusion of CBV as a fit parameter, is compared. The root mean square error in measured rate constant for the latter method is equivalent to that obtained by omit ting the first 2. 5-3 min of tissue data and neglecting the CBV term. Hence, added information about the physio logical state of the tissue is obtained without compro-The use of 18 F-labeled 2-f1uoro-2-deoxY-D-glu cose (FDG) and positron emission tomography (PET) to determine regional cerebral glucose was introduced in humans by Reivich et al. (1979), using the deoxyglucose model of Sokoloff et al. (1977), and extended to include phosphatase activity by Phelps et al. (1979a). Since then the method has been used to study a variety of pathological condi tions (Phelps et aI. , 1982; Yamamoto et aI. , 1984). The method estimates regional glucose utilization by comparing the observed tissue activity concen-

“…The factory-supplied software for our scanner uses a spatially invariant deconvolution to correct for this effect [4], as suggested by King [18] and Bergstrom [19]. Therefore, this correction can easily be added to the VOI calculation by including an additional convolution operation in (6), which models the scatter distribution.…”
