[c11] raclopride
The present study will attempt to resolve the controversy by measuring D2BP using both \[18F\]fallypride and \[11C\]raclopride in 39 adults, 13 within each of three BMI strata to represent a large BMI range, under controlled overnight fasting conditions following a period of dietary stabilization. The primary aims are to estimate the mathematical relationship between striatal D2BP and BMI and determine the within-subject correlations of D2BP derived from \[18F\]fallypride and \[11C\]raclopride.
