PBOTHSP character If yes, describe: , with options: Only 2 five minute frames were performed, only 2 5 minute frames were done according to the ADNI PIB protocol, A transmission scan was not performed therefore the scan was attenuation corrected using drawn (eliptical) regions of interest over the entire head (outside the skull)., The injected dose of C-11 PIB was 8.2 mCi instead of recommended dose of >10 mCi., MCH 60 min multiframe acquisition used. Tech advised to use PIB ADNI acquisition protocol, Wrong Imaging Parameters were used, subject injected with only 13.1 mCi because of delay due to scanner error, Placed a lot of towels under the neck, to make patient comfortablt, at 70min into scan - subject put hand into scanner, less than +/-1.5mci of desired dose injected
