Figure 2. Whole body images of [11C]d-methamphetamine in an African American (AA) and in a Caucasian (C) who received 7.18 and 6.99 mCi respectively and location of areas where ROI were obtained.

Figure 2

Imaging was started 4 min post injection moving from head to pelvis in 12 minute segments. The images have been decay corrected. Note the higher accumulation of [11C]d-methamphetamine in the lung of the AA than of the C. The hot spot on the abdominal cavity of the Caucasian corresponds to the stomach where [11C]d-methamphetamine accumulation was high but quite variable across subjects (may reflect its acidic environment that favors trapping of methamphetamine, which is a weak base).
