Radiology and Imaging Services


The Radiology Department at St. Catherine of Siena Medical Center provides comprehensive, state-of-the-art outpatient diagnostic imaging services in a convenient community hospital setting.

The dedicated team of radiologists is all sub-specialty-trained, board-certified physicians who are committed to providing top quality care using the latest technologies. They go out of their way to be available to review and discuss radiology tests with patients and referring physicians. With more than three dozen radiologists on staff, backed by the full resources of the entire, Island-wide Catholic Health Services organization, our patients are assured 24/7 access to state-of-the-art expertise and our mission-driven brand of individualized, personal care.

The Department of Radiology is accredited by the American College of Radiology in Magnetic Resonance Imaging (MRI), Breast Imaging, Computed Tomography (CT), Ultrasound (US) and Nuclear Medicine. The accreditations signify that the physicians supervising and interpreting your medical imaging meet the most stringent education and training standards. They also indicate that our imaging equipment has passed regular surveys by qualified personnel to ensure the highest quality possible.

Breast Health Services
St. Catherine’s Department of Radiology provides high quality personalized breast health care services, utilizing the most advanced digital imaging technologies. St. Catherine’s Breast Health Services meet all federally regulated standards and comply with the Mammography Quality Standards Act. For added support, a Breast Health Navigator (Registered Nurse) is made available to patients to help guide them through the process. The Breast Health Navigator, along with a physician, can help schedule appointments, and is a resource for patients with questions or concerns about their test results.

Diagnostic Imaging Services Include:

  • Diagnostic Radiology (X-Ray)
  • 1.5T MRI (Magnetic Resonance Imaging)
  • 64-Slice Helical CT
  • Nuclear MedicineUltrasound
  • Angiography and Interventional Radiology
  • Bone Densitometry
  • Breast Imaging Services Include:
  • High Quality Digital Mammography and Diagnostic Work-ups
  • High Resolution Breast Ultrasound
  • Image-Guided Biopsy
  • Stereotactic Biopsy
  • MRI-Guided Breast Imaging
  • A prescription is required for diagnostic imaging procedures.

St. Catherine of Siena Medical Center has a Siemens Multistar digital angiography suite is capable of performing the latest interventional procedures. This digital unit provides for more cohesive procedures that allow for additional angles to be studied in diagnosing complex areas like cerebral aneurysms, unusual carotid bifurcation anatomy, while using a fraction of the dose and contrast of conventional angiography. In patients with renal compromise, this is very important. Revolutionary design in equipment manufacturing allows for a ceiling-mounted C-Arm to be utilized so patients never need to be moved regardless of the complexity of the imaging.

Bone Densitometry
The state-of-the-art Bone Density Testing System can help identify if a patient is at risk for Osteoporosis. This is a safe, painless, quick, accurate, non-invasive test that measures the mineral content and density of bones.

Imaging Test to Detect Osteoporosis
DEXA Bone Densitometry: The "gold standard" of bone assessment methods. This non-invasive test is a baseline assessment for osteoporosis and can be completed ina matter of minutes. The test results will provide important information to assess the next steps in care for the prevention of future bone loss and in limiting a person's risk of a devastating injury. When an appointment is made for a mammogram, one can also be made for the bone density testing.

Routine x-rays, such as chest x-ray, x-rays of the hand, or G.I. Series, are valuable aids in assisting your doctor in diagnosing your illness. These examinations are performed by a licensed technologist utilizing the latest technology in Radiographic and Fluoroscopic x-ray equipment, under the direct supervision of a Physician.

The MRI/CT Scan Center has been completely renovated and upgraded with the latest equipment and technology. In this patient friendly center, our entrance, registration area and parking are private and separate from the hospital. This allows an efficient and focused team to concentrate only on the MRI/CT Scan patient. During the procedure, patients can enjoy music provided by the Center or music can be brought from home.

Reports are interpreted by a Board-Certified Radiologist and rapidly provided to the referring physician. In this new comfortable environment, a team of Registered Technologists, Registered Nurses, Board-Certified Radiologists, and Care Representatives work together to insure a stress-free experience.

MRIs are often ordered by a referring physician to help diagnose a variety of illnesses. Our center also performs advanced MR procedures as well abdominal, extremity and musculoskeletal imaging.

A CAT Scan is often used to provide images of virtually any part of the body in an extremely short period of time, often within seconds. Our CAT scanner utilizes spiral scanner technology to provide our physicians with this information both rapidly and accurately.

MRI with Sedation
The Radiology Department offers Outpatient MRI with Intravenous (IV) Sedation. Board certified physicians from the Department of Anesthesiology and radiologists work together during the MRI exam to provide the best of care. A light sedative is administered by the anesthesiologists who work with the radiologists to ensure accurate diagnostics, complying with the highest patient safety standards. Now children, individuals with developmental disabilities and claustrophobic patients no longer have to be afraid of MRI examinations. This is a great option for those who have a fear of being in a confined space or difficulty staying still. It is easy to obtain high quality images without the anxiety, stress, or inability to complete the test.

Nuclear Medicine/Radiation Therapy
The Nuclear Medicine section of our department offers diagnostic testing as well as Radiopharmaceutical Therapy. This section of the department is equipped with state-of-the-art gamma ray cameras and a computer system with SPECT capabilities. SPECT testing is used when imaging the function of the heart after a patient has a stress test or for cross sectional imaging of bone metabolism or infection localization. All Nuclear Medicine procedures utilize Radioisotope Imaging. The tracer dose of the radiopharmaceuticals is flushed from the system, typically by the next day. Patients referred for Radiopharmaceutical Therapy or Radiation Therapy meet with a Radiologist and/or a Radiation Oncologist for an evaluation and explanation of the planned treatment.

Ultrasound is a non-invasive imaging modality utilizing high frequency sound waves to image structures with the body. Our Ultrasound department features the latest, most advanced ultrasound units on the market today, complete with Doppler and Color Flow capabilities. These units are also utilized for non-invasive examinations of arteries and veins and are able to provide services from routine carotid artery screening to complete quantitative vascular flow analysis.

PET/CT Onsite Imaging
Positron emission tomography (PET) produces images of how the body functions and measures metabolic activity. Computed Tomography (CT) provides cross-sectional images of the body. PET/CT combines these two noninvasive procedures into one exam. For patients, this advanced technique reduces scan time and increases accuracy and comfort, while providing physicians with exceptional views of the whole body and its functions.

PET/CT combines CT’s fine anatomical detail with PET’s ability to detect biochemical abnormalities in the cell. This combination allows for earlier and more accurate detection of disease than either CT or PET alone. Because metabolic changes generally precede anatomic changes, PET can often provide earlier detection or more accurate staging than conventional imaging techniques. A PET/CT scan helps physicians diagnose a problem, determine the best approach to treatment and monitor patient progress.

The Benefits:

  • Early detection of disease
  • Precise tagging and localization of disease progression
  • Accurate monitoring of the effects of therapy

St. Catherine’s medical staff is experienced in PET and CT interpretation and is board certified in diagnostic radiology, with additional fellowship training and certification in nuclear medicine. Specially trained technologists are highly experienced in PET imaging.
