Figure 1 Two curves showing radioactive count of Tc-99m-MIBI after injection in tumour and control. (A) Early dynamic scan was performed for 5 min immediately after injection. (B) Early static scan was carried out 10 min after injection. (C) Delayed dynamic and (D) static scans were performed 2.5 h after injection. Blood flow index (F/E) was obtained from early dynamic scan from 30 s to 120 s after injection. Early retention index (H/G) was obtained from early dynamic scan from 4 min to 5 min after injection, and delayed retention index (J/I) was obtained from delayed dynamic scan 2.5 h after injection. Tumour retention index was calculated from early and delayed retention indexes
