WebA 9-min scan (16 gates/cardiac cycle) was acquired after inhalation of 3 MBq/ml of oxygen-15 labelled carbon monoxide at the rate of 500 m1/min over 4 min using a multislice PET camera. Noise reduction was performed on the gated image to enhance the definition of the ventricles before reslicing to the short-axis view.

Our ECG-gated cardiac NCCT images were acquired using a 64 detector-row CT scanner (Somatom Definition AS, Siemens, Germany) with the following parameters (Table 1): retrospective ECG gating, tube voltage = 120 kVp, collimation = 128 × 0.6 mm, gantry rotation time = 330 ms, pitch = … WebCase 3. Non-ECG-gated CTA in a 71-year-old male admitted to a community hospital after a road accident not only showed vertebral fractures, thoracic and pulmonary contusions and mural flaps in the descending aorta, but also gave rise to a diagnosis of acute traumatic AAD ().Therefore, he was referred to our hospital for emergent surgery. jinma holding co. ltd
