Nuclear medicine is a specialized field within radiology that uses small amounts of radioactive substances during imaging procedures to help doctors detect abnormalities and diseases at their earliest stages, allowing for the best clinical outcomes for our patients. The field of nuclear medicine contains important studies for identifying, evaluating, and treating a full spectrum of diseases within the body, including most types of cancers, neurological disorders, thyroid diseases, and gastrointestinal conditions.We provide studies to evaluate kidney function, kidney obstruction, portal hypertension, gastrointestinal bleed localization, lung scans for pulmonary embolism, and tumor diagnosis and staging, as well as seizure focus localization in the brain using PET/CT scans. Our services include the use of DaTscan (Ioflupane) to evaluate Parkinson's disease and other movement disorders, and amyloid brain scans for suspected Alzheimer’s disease. We offer Ra-223 therapy to alleviate bone pain—we were the first center in Connecticut to provide this treatment.

The Yale Gamma Knife Center is the only stereotactic radiosurgery unit in Connecticut dedicated to treating head and neck conditions. Gamma Knife radiosurgery is a type of focused radiation therapy used to treat certain types of tumors or abnormalities in the brain, its covering, and nerves and blood vessels. It is an effective, noninvasive alternative to brain surgery. Gamma Knife offers similar precision to open surgery with general anesthesia but with fewer risks and discomfort.Gamma Knife radiosurgery requires no incision and is done under local anesthesia.It is a one-day outpatient procedure and rarely requires hospitalization. Most patients return to their normal activities within 24 hours of the procedure. The experts in our Gamma Knife Center have more than 30 years of combined experience in radiosurgery. Our team works together to deliver a strong dose of precisely focused radiation. Gamma Knife can be used for both children and adults who meet the criteria for treatment with this advanced technology. Conditions we treat include: Brain metastases, most commonly from lung cancer, melanoma, breast cancer, colon cancer, renal cell cancer, and gynecological and genitourinary cancers Benign brain tumors such as meningiomas, acoustic neuromas (i.e., vestibular schwannomas), and pituitary adenomas Arteriovenous malformations Trigeminal neuralgia Intraocular melanoma Head and neck cancers, such as nasopharyngeal carcinoma Recurrent malignant primary brain tumors Glomus jugulare tumors Essential tremor (thalamotomy with Gamma Knife)

The Department of Therapeutic Radiology works closely with the Yale Cancer Center to comprehensively evaluate and treat patients in need of any form of radiation therapy. We are widely known for our innovative approach to treatment, and have extensive experience in the following specialized areas: Breast cancer radiotherapy Central nervous system radiotherapy Gastrointestinal radiotherapy Head and neck radiotherapy Pediatric radiotherapy Prostate and genitourinary cancer radiotherapy Spine radiosurgery Stereotactic body radiotherapy (SBRT) and Gamma Knife® radiosurgery Thoracic radiotherapy Total skin electron beam therapy (TSEBT) Our primary goal is to ensure our patients receive the right amount of radiation at the tumor site, with as little impact as possible on the surrounding healthy tissue. Our treatment planning program, also known as medical dosimetry, is focused on just that, providing a highly individualized external or internal radiation treatment course for each patient. Site of the only Gamma Knife® center in Connecticut One of the largest U.S. centers for stereotactic body radiotherapy (SBRT) First program in Connecticut to incorporate SpaceOAR hydrogel technology in prostate radiotherapy First and only program in New England to combine SpaceOAR technology with Calypso radiofrequency tracing for precision prostate surgery
