  • Traditionally, abdominal imaging work-up was done with survey, Barium contrast radiography or ultrasound.
  • Computed tomography allows complete assessment of the abdominal and pelvic cavity, as well as the thorax and other body parts within a few minutes.
  • Computed tomography uses ionizing radiation, therefore particular health and safety measures apply.
