CT SCAN OF NECK

CT scan of Neck Overview

A CT scan (Computed Tomography) is a diagnostic imaging procedure that integrates X-ray technology with a computer to scan the neck region, revealing intricate details of its internal features. This examination is often performed to diagnose and track diseases that affect the neck, throat, and the associated soft tissues. 

What is a CT scan of the Neck? 

CT scan of the neck involves the use of x-rays and a computer to obtain precise pictures of the neck area and its structures. The procedure entails the patient lying flat on a table which moves into a big cylindrical structure, the CT scanner. The X-ray machine positioned around the CT scanner makes numerous X-ray photos, which are reconstructed into volumetric images of the neck.

There are two common types of CT scans of the neck: 

• Without contrast: This scan is typically done to assess the bones and soft tissues and does not use contrast dye. 
• With contrast: This type uses contrast dye to view soft tissues and blood vessels.
