The effect of neuroanatomical structure size, shape, and position versus spatial tomographic resolution on quantitation in positron computed tomography was investigated. For neuroanatomical structures, voxel sizes in excess of 3 ml exceeded the volume of most structures examined. When the voxel size exceeded structure volume, calculated recovery coefficient (fraction of the true isotope concentration measured in the image) fell to less than or equal to 42%. Partial volume effects in the plane… CONTINUE READING
