The best images are captured by the most skilled and certified technologists, using the most appropriate technology, interpreted by board-certified radiologists. That's what you'll find at St. Lawrence Health System's Imaging suites.
Between Canton-Potsdam Hospital, Gouverneur Hospital, and Massena Hospital, we have the best-equipped Imaging suites in the North Country. We offer both 64- and 128-slice CT scanners featuring the newest low-dose technology available for minimizing exposure to radiation, and both 1.5 and 3 Tesla open bore high field MRIs. We have iCAD (computer-aided detection) software for more accurate mammography readings, 2D/3D mammography, MRI breast, and traditional and ABVS ultrasound, allowing us to provide full-service women's breast imaging. For women planning a family, we provide 3D/4D ultrasound. We are Picture Archival Communication System (PACS) capable, which means we can store and transmit images. We are currently able to transmit images to a number of other facilities. Images are available for interpretation immediately.
Definitions and Locations
We understand the different names for imaging procedures may be a bit overwhelming and confusing. Here is a brief explanation on each service to assist you in better understanding them, and where you can go for each service.
CT Scan (Computerized axial Tomography)
combines a series of X-ray images taken from different angles around your body. It uses computer processing to create cross-sectional images (slices) of the bones, blood vessels, and soft tissues inside your body. CT scan images can provide a higher level of detail when needed.
Mammography, or Mammogram
is an X-ray of your breast. Traditional mammography creates a 2D image of the breast and is a screening and diagnostic tool used to detect and diagnose breast cancer. Together with regular clinical exams and monthly breast self-examinations, mammograms are a key element in the early diagnosis of breast cancer. We offer 2D and 3D mammography at all four of our sites. 3D mammography, also known as Digital Breast Tomosynthesis (DBT), is an advanced form of breast imaging that uses a low-dose x-ray system and computer reconstruction to create three-dimensional images of the breast, which improves the early detection of breast cancer during screening and diagnostic exams; this is especially instrumental in women with dense breast tissue.
MRI (Magnetic Resonance Imaging)
is a technique that uses a magnetic field and radio waves to create detailed images of the bone, organs and tissues within your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI. The MRI machine is also equipped to produce 3-D images that may be used to better visualize specific areas for diagnostic purposes. SLHS has two different strength MRI scanners which allows us to best serve our patient population. We have a 1.5Tesla MRI at Potsdam and Gouverneur, and a 3Tesla MRI in Canton and Massena.
Nuclear Medicine Imaging
is used to evaluate bone, assesses your organ function and structure, and identifies the presence of disease. It uses small amounts of radioactive substances known as tracers, these tracers are either swallowed, inhaled, or injected into a vein in your arm depending on what part of the body is being imaged. The tracers are designed to target and image a specific area of your body.
PET/CT Scan (Positron Emission Tomography)
is an imaging test that allows your provider to check for diseases in your body while using a radioactive sugar. These tracers are injected into a vein in your arm where the organs and tissues then absorb the tracer. PET provides information regarding glucose metabolism of tissues. Cancerous tissues are glucose-hungry and show up differently on PET scans than healthy tissues, because of their different glucose metabolisms. Your provider may use PET/CT to determine if an area is cancerous or to evaluate for any spread of cancer if you have already been diagnosed with it. PET/CT can also be used for cardiac imaging, and neurologic imaging (Parkinson’s disease, dementia, etc.)
Ultrasound (Automated Breast Volume Scanner)
is an essential tool in breast cancer detection if you have dense breast tissue. An ultrasound of each breast is performed using a high frequency ultrasound probe which sweeps across the whole breast. A 3D image of the breast is produced that allows a clearer, more detailed image as a follow-up to a conventional mammogram. (Accredited by the American College of Radiology/ACR.)
uses high-frequency sound waves to view inside your body. Ultrasound can be used to evaluate organs, structures, fetal anatomy, and can provide guidance for special procedures. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging, and your provider will determine which exam should be used for your situation.
are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of bone, tissues and structures inside your body.
