Abdominal CT scan and pelvic CT scan are techniques that use a CT scanner to reconstruct images of the abdominal and pelvic structures to diagnose and detect any pathological abnormalities. The abdominal/pelvic CT scan procedure without contrast injection is simple and non-invasive, with a very low risk of radiation exposure.
