What is virtual colonoscopy?

Virtual colonoscopy is a non-invasive diagnostic technique, which generates three-dimensional images of the colon, in real time and without the introduction of any endoscopic probe

How does virtual colonoscopy work?

The exam lasts about 20 minutes.

A CT scan is performed and the software acquires the images which will then be processed by the radiologist, simulating a traditional colonoscopy.

In some specific cases, at the radiologist’s discretion, contrast medium is also administered into a vein.

Why is virtual colonoscopy prescribed?

With virtual colonoscopy it is possible to identify some pathologies of the colon (neoplasms, polyps, diverticula) without the risks and contraindications associated with a traditional endoscopic investigation.

Virtual colonoscopy is an accurate, safe and well tolerated diagnostic method, and represents a valid alternative to conventional endoscopic investigation.

Is it a painful or dangerous exam?

The examination is absolutely not painful and does not pose any risk to the patient’s health.

The exam consists of a Computerized Axial Tomography (TAC), whose data are processed through specific software that produces three-dimensional images of the colon.

The specialist can thus observe the inside of the colon-rectum as if it were a normal endoscopic investigation.

Who can perform virtual colonoscopy?

Given the low invasiveness, virtual colonoscopy is indicated for all patients, and in particular for those who, for whatever reason, have a contraindication to performing the traditional endoscopic examination.
