^99mTc-HMPAO (brain) male rat imaging. Composite 0–60 min images and regions of interest (ROIs) used as (a) receiving 0 mg/kg 13-RA as the control (C), (b) receiving 0.3 mg/kg 13-RA as the low-dose group (L), and (c) receiving 0.5 mg/kg 13-RA as the high-dose group (H). Brain ROI: BG: background and WB: whole body ( whole body of rat image).
