The parameters for microCT were 80 kVp X-ray tube voltage, 0.5 mA tube current, 175 ms exposure time per step, and 120 steps over 220°. During the uptake time, the animals were awake and kept warm on a temperature-controlled heating pad at 37°. The animals were under anesthesia with...
CT images were acquired using the 16-section multidetector scanner with an automatic exposure control system, performing 3D mA modulation according to the patient’s body size and attenuation level, ranging from 15 to 50 mA; the tube voltage was 120 kVp. Initial PET acquisition was performed in...
