Radiologic sign

The dark areas on both sides of the intestines indicate that air is present in both sides. This is called "Rigler's sign".

A radiologic sign is an objective indication of some medical fact (that is, a medical sign) that is detected by a physician during radiologic examination with medical imaging^[1] (for example, via an X-ray, CT scan, MRI scan, or sonographic scan).
