An abdominal CT scan is a CT scan sub-type that provides detailed and high-resolution 3D images of your abdominal cavity. 

The abdominal CT scan is a painless and non-invasive image diagnostics procedure that enables the doctor to view the insides of the abdomen and the surrounding structures, such as the blood vessels, organs, and bones. 

The abdominal CT scan is generally recommended after a physical examination yields inconclusive results and the doctor needs more information to make an accurate diagnosis.   

Also, the abdominal CT scan is frequently preferred over a conventional X-ray, as the former is able to deliver detailed images and much more clarity. 

In cases where the abdominal CT scan needs to check hard to scan regions of the abdomen, a contrast dye can be administered for clearer images. The contrast material has nearly no side effects and gets flushed out via urine within 24 hours.
