Benefits and Risks

Almost all medical procedures, including imaging procedures that use radiation, have risks associated with them.

Radiation in Medical Imaging has its benefits

For a brief snapshot that shows the power of medical imaging, consider these findings: 

  • Use of mammography to screen for breast cancer has resulted in a declining death rate, improved survival rate, and better treatment options.1 
  • Performing coronary CT angiography to examine the heart vessels in patients with chest pain helps guide treatment decisions with high accuracy and avoids costly invasive procedures.2 
  • Incorporating advanced medical imaging procedures into healthcare has significantly increased life expectancy in the US.3
