Image-guided radiation therapy (IGRT)

Also known as: IGRT

Radiation oncologists use image-guided radiation therapy, or IGRT, to help better deliver the radiation to the cancer since tumors can move between and during radiation treatments. An example of image-guided radiation therapy is cone beam CT imaging, a procedure involving a radiation machine that obtains a scan of the patient in the treatment position just before the radiation therapy treatment is delivered. The physician reviews the scan and makes any adjustments immediately before treatment is delivered. In the case of prostate cancer, the prostate can move from day to day due to the variable size of the adjacent rectum and bladder. By adjusting the aim of the radiation machine on a daily basis using cone beam CT, precision is enhanced and the risk of side effects is significantly reduced.

Deep inspiration breath hold technique for breast cancer treatment (DIBH)

DIBH is a relatively new technique for patients at risk of receiving radiation to the heart as part of breast cancer treatment. Not all patients require DIBH techniques, and your radiation oncologist can help you determine if this technology would reduce the risk of heart damage. Recent studies have found a reduction in the risk of heart damage in appropriately selected patients with the use of this technique. Since many patients with breast cancer receive radiation therapy as part of their treatment, this technology is an important option for many patients receiving radiation treatments.
