Abdomen Pelvis
The pelvic cavity is divided into two parts, the greater pelvis, and the lesser pelvis. The greater pelvis is part of the abdomen, so it is also referred to as the false pelvis. The lesser pelvis is part of the pelvis, so it is also called the true pelvis. The Sacrum and coccyx are located posteriorly.
Reasons for a CT scan of the Abdomen
The abdomen contains organs of the gastrointestinal, urinary, endocrine, and reproductive systems. A CT scan of the abdomen may be performed to assess the abdomen and its organs for tumors and other lesions, injuries, intra-abdominal bleeding, infections, unexplained abdominal pain, obstructions, or other conditions, particularly when another type of examination, such as X-rays or physical examination, is not conclusive.
A CT scan of the abdomen may also be used to evaluate the effects of treatment on abdominal tumors. Another use of abdominal CT is to provide guidance for biopsies and/or aspiration of tissue from the abdomen.
