Radiology Services

At Yale-New Haven Hospital Saint Raphael Campus, we offer comprehensive imaging services. We have been pioneers in implementing and developing imaging programs with emphasis on clinical excellence and quality measures.

Advances in radiology have given physicians more choices than ever in using medical imaging technologies to diagnose and treat diseases. Today's radiology goes well beyond traditional X-rays to include treatments that minimize radiation exposure for patients. Our technology includes a state-of-the-art 3T MRI with advanced capabilities for functional imaging, MDCT, PET/CT imaging and bi-plane digital angiography. We have also been at the forefront of breast imaging initiatives with early implementation of digital mammography, ultrasound and breast MRI, as well as the variety of imaging guided interventional procedures.

At Yale-New Haven Hospital Saint Raphael Campus, we pride ourselves on the training, experience, and top-quality care that our radiologist specialists provide including such services as:

Our board-certified radiologists with fellowship training and sub-specialty expertise provide referring physicians and patients timely and accurate results of imaging examinations. Our caring staff members, including radiologic technologists, administrators, nurses and clerical personnel are here to provide you with the best patient care. We are also a leader in radiology education with an impressive tradition of teaching excellence and clinical research performed with radiology residents.

Extended Hours for Specialty Services

To accommodate increased volume, we have expanded weekend hours for certain specialty services.

PET/CT scans are available two Saturdays per month from 7 am - 3:30 pm. Monday through Friday hours for PET/CT exams are 7 am - 3:30 pm. Physicians may call 203.789.3646 during normal weekday hours to schedule a PET/CT exam for their patients.

Weekend ultrasound services are available for inpatients and outpatients from 7 am - 4 pm on Saturdays and Sundays.

Hours for other diagnostic radiology exams are available seven days a week from 7 am - 8 pm. Some exams may require appointments. Please call 203.789.3124 for more information or to schedule an appointment.

Bone Density Testing

An estimated 28 million Americans -- 80 percent of them women -- have osteoporosis, a disease in which bones become weak, fragile and more likely to break. But many people don't know they have it. At Yale-New Haven Hospital Saint Raphael Campus, we offer a fast, easy and painless test that can show if you are at risk for broken bones associated with osteoporosis. Learn more.

Breast Imaging

At Yale-New Haven Hospital Saint Raphael Campus, we are at the forefront of new breast imaging technologies to detect and diagnose breast health. In addition to mammograms (including digital mammography), we offer breast ultrasound, CT or CAT scan, ductography, magnetic resonance imaging (Breast MRI), and positron emission tomography (PET scans).

With accreditation in four key areas of specialized radiology, we are a Breast Imaging Center of Excellence, designated by the American College of Radiology (ACR). That means we have earned accreditation in all of the College's voluntary, breast-imaging accreditation programs and modules, in addition to the mandatory Mammography Accreditation Program.

We are fully accredited in the areas of mammography, stereotactic breast biopsy, breast ultrasound and ultrasound-guided breast biopsy. Peer-review evaluations, conducted in each breast imaging modality by board-certified physicians and expert medical physicists determined that we have achieved high practice standards in image quality, personnel qualifications, facility equipment, quality control procedures and quality assurance programs.

  • For information on breast MRI, please call 203.789.4120
  • For information on breast ultrasound, please call 203.789.3244
  • For information on image-guided procedures such as ductography, fine needle aspiration, MRI-guided imaging, stereotactic biopsy, ultrasound-guided needle biopsy, please call 203.789.3124
  • For information on mammograms, please call 203.789.3124

Interventional Radiology

This minimally-invasive, targeted treatment by radiology specialists eliminates open surgery and reduces recovery time, as well as pain. Treatments include angioplasty and stenting (improve blood flow) and thrombolysis (clot removal). Learn more.


Yale-New Haven Hospital Saint Raphael Campus is equipped with a state-of-the-art 1.5 Tesla MRI and the new 3 Tesla MRI, the first such unit in the state used for clinical imaging. Both magnets are open at each end and offer easy, comfortable and painless exams. MRI tests can be used for varied studies, including

  • Non-invasive coronary angiography to study the heart vessels
  • Suspected brain lesions including study of brain functions (e.g., speech, motor, sight)
  • Stroke detection and areas at risk for stroke
  • Prostate tumor detection
  • Spine conditions (e.g., spinal cord lesions, disc disease)
  • Bones and joints, including the knee and small joints, cartilage evaluation
  • Suspected abdominal disease including vascular lesions (e.g. aorta, renal arteries and other blood vessels)
  • Cancers of the head and neck

For more information, please call 203.789.4120.


Ultrasound, also called sonography, is an imaging technique that uses high-frequency sound waves to scan and project visual images from inside the human body to produce a picture called a sonogram. Because no ionizing radiation (X-ray) is involved in ultrasound imaging, it is commonly used as a diagnostic tool in obstetrics.

At Yale-New Haven Hospital Saint Raphael Campus, we keep up with the latest developments in ultrasound technology and use the technique to diagnose an array of pathologies and disorders including:

  • Gall bladder and liver disease
  • Abdominal cysts and tumors
  • Various gynecological conditions

Ultrasound is also used to diagnose a variety of heart conditions and to assess damage after a heart attack or other illness.

Doppler ultrasound is a special technique used to examine blood flow. Doppler images can help the physician to see and evaluate:

  • Blockages to blood flow (such as clots)
  • Narrowing of vessels (which may be caused by plaque)
  • Tumors and congenital malformation
