FIGURE 1. PET images of normal and cycloheximide-treated rats. Four hours after injection of 5 mg of cycloheximide per kilogram (intraperitoneally) into treated rat, both animals were injected with approximately 51.8 MBq of 18F-annexin V (851 kBq/µg protein) and imaged for 2 h starting immediately after injection of radiotracer. In each panel, untreated animal is on left and treated animal is on right. All 3 false-color images were windowed using same logarithmic scale from 0 to 481 kBq/cm3. (A) Transverse image from 10-min time frame beginning at 0 min shows higher uptake in treated liver (R). (B) Coronal image from 10-min time frame beginning at 40 min; urinary bladder shows high uptake in lower abdomen. (C) Transverse image from 10-min time frame beginning at 1 h 30 min shows higher uptake in treated liver (R).
