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.
