Radiation Dose Reduction and Optimization

At Stanford Medicine Imaging, we understand that radiation exposure is a concern to referring physicians and their patients. CT is a powerful imaging tool to diagnose a wide variety of disorders such as cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal abnormalities. Stanford Medicine Imaging is committed to the radiation safety principles of ALARA (As Low As Reasonably Achievable):

  • Image when there is a clear diagnostic benefit
  • Focus imaging to the area of interest
  • Use the latest advances in CT Technology to achieve diagnostic quality imaging with the lowest radiation exposure:
    • Dual-Source CT scanning offers the fastest temporal resolution and low radiation exposure for cardiac scans
    • Dual Energy offers a higher fidelity and tissue characterization than previously possible in CT
  • New Iterative Reconstruction allows reduction of image noise and improve low contrast detectability and enhance image quality
  • Individualization and Customization - optimizing imaging technique to each patient
  • Advanced radiation dose modulation techniques measure patient size and deliver a specific radiation dose unique the patient's body habitus
  • Weight based contrast medium injection protocols are patient and organ specific to optimize patient safety, comfort and image quality.
  • Technologists Education
  • Newest Generation State of the Art Equipment

For more than one hundred years, Stanford's Department of Radiology has been making contributions to medical and surgical advances by pioneering innovations in image-based patient care, research, and education. We are preparing for the future with active research to discover new methods to optimize imaging and reduce radiation dose. We are also implementing new innovative processes of cumulative structured dose reporting, tracking and notification systems.
