The Julia and Ned Arnold Center for Radiation Oncology at NewYork-Presbyterian Queens is a leading center for radiation oncology in the country and a leading component in the hospital's Cancer Center. The center boasts a highly trained staff, the most current and advanced treatment capabilities, and an uplifting and caring environment for patients. The medical staff works with patients, families and collaborating physicians to get the best possible outcomes. They are all highly qualified, caring and experienced faculty members of the Weill Medical College of Cornell University. The center is easily accessible for patients with free parking, proximity to public transportation and special transportation arrangements for those who need it.

The center’s specialists are pioneers in the field of radiation oncology. The research at NewYork-Presbyterian Queens is driving continual progress in the fight against many forms of cancer.

Image Guided Radiation Therapy (IGRT) is the next big step in radiation treatment for cancer. IGRT allows for precise aiming of a stronger radiation beam at the tumor target area while minimizing the radiation exposure of surrounding healthy tissue.


External Beam Therapy 

There are two forms of radiation therapy. In external beam therapy, X-rays or electron beams are directed at the tumor from outside the body using a machine called a linear accelerator. At the Arnold Center, patients are able to receive external beam therapy using Image Guided Radiation therapy (IGRT) as needed. IGRT allows for cone beam images to be taken just before treatment and the making of last-second adjustments to the treatment just before radiation is administered. IGRT allows for the precise aiming of a stronger radiation beam at the target area while minimizing the exposure of surrounding healthy tissue to the radiation. The department also has the capability to use IMRT (Intensity Modulated Radiation Therapy) treatment as appropriate.


In Brachytherapy, a radioactive source is introduced directly into the body, next to or inside the tumor, leading to a high-intensity application to small areas. Depending on the needs of the patient, this may be done in one of two ways: The material can be sent by remote control through a catheter or thin tube and then withdrawn, or it can be implanted during a minor surgical procedure. The Arnold Center utilizes the latest Brachytherapy machine and equipment. It is one of the only centers with a fully dedicated brachytherapy suite, including an adjacent Recovery Room within the center.

Stereotactic Body Radiation Therapy

Stereotactic Body Radiation Therapy (SBRT) is a specialized radiation treatment for the body. Stereotactic means that a specially designed 3-D coordinate-system is used for the exact localization of tumor. SBRT differs from standard radiation therapy in that it kills tumors with a high potent biological dose which improves the cure rates for the tumor while delivering little radiation to the surrounding healthy tissue. Indications for SBRT involves primary lung cancer, pancreatic tumors, bile duct tumors, primary and metastatic liver tumors, kidney tumors, pelvic tumors, sarcomas, metastatic tumors throughout the body and more. 


Because the effective treatment of cancer is a constantly evolving process, The Arnold Center conducts research as a means of advancing day-to-day practice. Center physicians develop new treatment programs from a continuous review of the center’s own experience. The goal is to produce more effective treatments overall, and to increasingly tailor treatment to the individual patient’s cancer.


The Arnold Center conducts an ongoing program of professional education essential to creating a superior clinical environment, preparing residents and fellows and keeping current practitioners up-to-date with new information. Physicians from the United States and abroad come to this center for specialized training.
