Imaging Tests for the Prevention and Detection of Colorectal Cancer

Aging adults are encouraged to undergo specific screenings that are designed to observe susceptible body areas for warning signs of potential disease. Because colorectal cancer is the number-two cause of cancer-related deaths in the United States, guidelines for screening have been established. Research indicates that early detection and treatment of suspicious polyps and growths is paramount to positive patient outcomes. We are pleased to provide the services that physicians and patients in the Humble and Houston areas need to better protect health and wellness.
Screening for Colorectal Cancer
There are several types of screenings that physicians may order for assessment of the lower digestive tract, colon, and rectum. These tests are important even in the absence of symptoms because the whole goal is to prevent a disease from progressing to the point where symptoms are obvious. Curative therapy is most effective in the early stages of a disease, so men and women are encouraged to adhere to screening guidelines laid out for them.
Some of the common screenings include:
- Colonoscopy
- Computed tomography colonoscopy
- Double-contrast barium enema
- Sigmoidoscopy
Computed tomography colonoscopy and double-contrast barium enema are methods of imaging that are performed in radiology facilities.
The CT colonoscopy obtains images of the colon using low-dose radiation as an alternative to the standard physical observation of the inside of the colon (standard colonoscopy). This screening does involve the insertion of a small tube into the rectum. A small amount of air or carbon dioxide is used to inflate the tube slightly, which allows for imaging of the abdomen for the evaluation of abnormalities such as colon polyps. The CT colonoscopy is a tolerable screening that does not require sedation.
The double-contrast barium enema is a type of x-ray that allows a radiologist to interpret what is observed on films of the lower gastrointestinal tract. Air, as well as barium solution, is involved in this screening, and the entirety of the rectum and colon are examined via x-ray imaging of the abdomen.
Imaging is a productive diagnostic tool in internal medicine, and as a screening measure for potentially serious health conditions. We are happy to provide personal service to patients who visit GO Imaging in Houston or Humble, and prompt response to physicians who refer to our facilities.
