About The Test

CT Neck & Upper Thorax test is a radiology examination aimed at getting cross-sectional images of the neck and upper part of the thorax using computed tomography (CT) technology. It is frequently performed to evaluate and track numerous conditions related to the neck, throat, and upper components of the chest region. 

What is CT Neck & Upper Thorax?  

CT Neck & Upper Thorax is performed using a CT scanner that captures images of the neck and upper thoracic area. The machine revolves around the individual’s body and releases X-ray beams that go through the body. Sensors detect these rays and use them to produce images of the different organs. Generally, the scan is done along with contrast agent for better quality images. 

Types of CT Neck & Upper Thorax 

These scans use various methods to obtain CT Neck & Upper Thorax images: 

  • No contrast: useful for patients that have kidney disease or have a known allergy to the contrast media. 
  • With contrast: it is applied to improve the quality of the images and check for vascular defectives.  
  • High-Resolution CT: used in imaging small lesions or small abnormalities.

  1. Keeping the patient on the CT scanner table and explain how to remain still and hold their breath until the test is over. This is referred to as the preparation stage.  
  2. The next phase involves the amputation of arms. In this phase a rotating CT scanner is centred on the patient and while scanning, X-ray beams execute and travel through the body.  
  3. To better image quality, a contrast agent may be given through an intravenous injection in the arm. This refines the image quality. 
  4. This complex process follows the scanning. The captured x-rays undergo processing using a special machine that enables them to form different geometric objects.
