The best clinicians in the field.
Our mission is to significantly expand the use of virtual colonoscopy (CT Colonography) for colorectal cancer prevention and screening.
ColoWatch® brings together clinical, business, and technical leaders committed to delivering reliable, standardized performance and interpretation of virtual colonoscopy studies.
A virtual colonoscopy study at any facility in the ColoWatch® network is performed using the same protocol and quality-control tools developed by ColoWatch®. Each study is delivered securely through the cloud to our network of board-certified radiologists expertly trained in ColoWatch®'s advanced 3D visualization software.
The result: reproducible, accurate interpretation of virtual colonoscopy studies by the best clinicians in the field.
Why Virtual Colonoscopy?
Over the last 25 years, virtual colonoscopy has been proven to be a highly accurate, extremely safe, convenient, and cost-effective method for colorectal cancer prevention and screening.
- Reliably detects clinically relevant polyps that are precursors to colorectal cancer
- Safely confirms the absence of disease in over 90% of screened individuals
- Requires no sedation and allows for a faster return to daily activities
These advantages support virtual colonoscopy as the screening study of choice for colorectal cancer in average-risk individuals.
As an added benefit, ultra–low-dose CT studies may also identify other unsuspected medical conditions in some patients, including cancers outside the colon, osteoporosis, and certain cardiovascular diseases.
Widespread implementation of virtual colonoscopy has the potential to save thousands of lives in the United States alone and generate billions of dollars in annual healthcare savings.
