CT of the abdomen and pelvis
Compare with any previous exam.
Liver, spleen, adrenals and kidneys
Scan through the entire volumes and look mainly for focal changes.
- The thickness of the adrenal glands is normally up to 1.0 cm.
- Look at the gallbladder and biliary tract for visible stones or dilatation.
- Also exclude hydronephrosis of the kidneys.
Switch to a lung window (wide attenuation range), with main focus on the anterior wall, where gas most likely appears.
While in this window, also have a glance at the bases of the lungs for pleural fluid or obvious lung tumors.
Look mainly in the hepatorenal recess and inferiorly in the pelvis.
Look mainly around the aorta and iliac arteries.
|Retrocrural space||6 mm|
|Gastrohepatic ligament||8 mm|
|Upper paraaortic region||9 mm|
|Portacaval space||10 mm|
|Porta hepatis||7 mm|
|Lower paraaortic region||11 mm|
- Exclude dilatations.
- Check the intestinal wall for any thickening of over 5 mm. Focal, irregular and asymmetrical gastrointestinal wall thickening suggests a malignancy. Segmental or diffuse gastrointestinal wall thickening is most often due to ischemic, inflammatory or infectious disease.
- Exclude aneurysm, which is generally defined as over 3 cm.

Quick look for obvious wall thickening.
Males: Quick look at the prostate for obvious irregularities.
Females: Look mainly at the locations of the ovaries for any expansions.
Any signs of damage.
Other extra-peritoneal volumes
Quick overview to exclude mainly obvious soft tissue expansions such as hematomas (see CT of muscular hematoma).
Example report in a normal abdomen:
No free gas or ascites
