“…Our methods and results are reported in detail in a number of papers [I 1, 13-15,22, 27-29]. Since June 1982, the addition to our equipment of an advanced, high-resolution, high-sensitivity scanner, the Neuro-PET [8,9,12, 321, has dramatically improved our diag--be calculated from a fairly simple equation. In the simplest possible case, that of no unmetabolized tracer and no backflow, the equation for R would be where cg is the glucose plasma concentration (assumed constant during the study period), c,(t) is the concentration of tracer in the tissue at the time of the scan, c, (t') is the concentration of tracer in the plasma, and LC is Sokoloff s lumped constant [34], which corrects for the kinetic differences between glucose and "FDG.…”

“…[10] for each group, it is possible to calculate the autocorrelation function for the group-averaged images. For the discrete case, this is given by [22], [20], [27], [26] Between Group Test for spectral equality [10], [11], [28] Improved estimate of difference Estimated SDF, equal var [30], [31], [32], [33], [26] Estimated SDF, unequal var [22], [23], [34], [26] Known SDF, unequal var [20], [34], [35], [26] Known SDF, equal var [20], [24], [33], [26] Linear discriminant function Estimated SDF [10], [11], [24], [37], [38] Known SDF [20], [24], [37], [38] a SDF ϭ spectral density function.…”

“…Ten male patients, age 51 to 76 years, clinically diagnosed with organic mental disorders attributed to alcoholism (27)(28)(29)(30) and seven age-matched volunteers were studied using the Neuro-PET scanner (31 ). Images were acquired parallel to the canthomeatal (CM) line with an approximate transverse spatial resolution of 7 mm full width at half-maximum (fwhm) and an axial resolution of 11.5 mm fwhm.…”
