Innovative Low-Dose Radiation Therapy Provides Relief to Osteoarthritis Patients
February 18, 2026 – Nashua, NH – The Radiation Center of Greater Nashua announced today that it is offering cutting-edge Low-Dose Radiation Therapy (LDRT) to patients with osteoarthritis.
LDRT is a non-invasive, anti-inflammatory treatment that uses low doses of radiation to reduce pain and improve joint function in patients with osteoarthritis (OA). OA is the most common form of arthritis, affecting millions of people worldwide.
The Center is one of the only freestanding radiation centers in New England offering LDRT. The innovative treatment is gaining recognition in the United States for its effectiveness in managing OA symptoms, especially when other treatments have failed to provide relief.
“LDRT has been used in Europe for decades, and we’re pleased to now offer it to our patients who are suffering from osteoarthritis pain,” said Dr. Vivek Patel. “We’ve treated dozens of patients and have alleviated pain by targeting specific joints, reducing inflammation and improving mobility.”
LDRT targets the inflamed joint(s) with precisely targeted, low-dose radiation. “Unlike higher doses of radiation used in cancer treatment, the low doses of radiation in LDRT focus specifically on reducing inflammation without significant risk of side effects,” said Medical Director, Dr. Stephen Harris.
LDRT is recommended for people who have tried treatments like physical therapy, medications or injections to no avail. It is also for people who are interested in limiting or eliminating medication use for OA, are looking for a non-surgical option to manage their OA pain and are over 40 years old.
The treatment consists of six 10-minute sessions. LDRT does not involve needles and is an outpatient procedure, meaning patients can return home immediately after treatment. Each patient’s treatment is tailored to the specific joint causing pain.
