PET and Radiation Oncology

Types of External Beam Radiation Therapy

Delivering high doses of radiation from an external radiation source, this form of treatment specifically targets the affected cancer site and lessens the amount surrounding healthy tissue exposed to radiation. Examples of external beam therapy include:

  • Stereotactic Radiosurgery (SRS) – This non-invasive, outpatient procedure enables physicians to treat head and brain lesions without the surgery. With finely focused beams of gamma radiation, SRS minimizes radiation exposure to healthy, surrounding tissue and eliminates risks associated with surgery or an open incision. This adaptive therapy maximizes patient comfort and allows for treatment of lesions that were previously considered inaccessible or inoperable through traditional treatments.
  • Image-guided Radiation Therapy (IGRT) – IGRT is an all-in-one machine that enables our doctors to choose the most appropriate treatment for cancers located throughout in the body. It’s precision and effectiveness have proven very successful in the elimination of may different forms of malignancies, including those within delicate tissues of the head and neck.

To accommodate for "respiratory gating," treatments can compensate for tumor movement due to the patient's breathing, which is very beneficial for addressing lung cancer and other tumors in the chest or abdomen that are prone to move.

  • Intensity Modulated Radiation Therapy (IMRT) – IMRT combines the highest level of patient comfort with fewer side effects than standard radiation therapy. It is a highly precise radiation instrument that spares normal tissue, allows for superior dosing and treats tumors near critical areas.
  • Electron Beam Therapy – This treatment used primarily in addressing shallow areas of tissue and mitigates radiation exposure to underlying normal tissues.

Brachytherapy Approaches

Brachytherapy involves the implantation of tiny radioactive pellets directly into the center of a cancerous mass. Different brachytherapy techniques are used for Mammosite, SAVI, cervical and vaginal cancer treatment, and prostate seeds.

  • SAVI Breast Cancer Brachytherapy Applicator – SAVI delivers radiation from inside the breast, only targeting tissue where cancer is most likely to occur. Since each catheter individually delivers radiation, treatment is customized to the patient. SAVI enables doses to be contoured to size, shape and location. Treatment can be completed in five days and radiation exposure to healthy tissue and organs is minimized. Upon completion of treatment, most women can resume normal daily activities.
