Imaging services

Buffalo Hospital's Medical Imaging department maintains a full range of advanced diagnostic technology for peering inside the human body to identify medical conditions or disease.

We offer a wide range of diagnostic tests, including X-ray, fluoroscopy, mammography, ultrasound, computerized tomography (CT Scan), MRI, PET/CT and nuclear medicine. Most images are produced in a digital format, making them rapidly available for your doctor to view.

CT (Computed Tomography) Scan

The CT scanner is a doughnut-shaped machine that takes pictures of cross-sections of the body, called "slices." An X-ray tube moves in a circular fashion around the area being scanned. The rays are picked up on a scanner, fed into a computer and seen on a computer screen, revealing a highly detailed, two-dimensional view of the area that was scanned.

A CT scan provides fast, detailed, high-resolution images typically used to detect cancer, spinal injuries, pediatric conditions, trauma and other disorders.


Buffalo Hospital offers digital mammograms to screen for breast cancer and evaluate other breast abnormalities. Learn more about our mammography services.


MRI, or magnetic resonance imaging, is among the most advanced ways of seeing into the human body, making it the preferred diagnostic tool for brain, spinal cord and joint disorders. Doctors receive highly refined images of the body's interior without surgery. Strong magnets and pulses of radio waves are used to manipulate the natural magnetic properties in the body. This technique makes better images of organs and soft tissues than those of other scanning technologies.

An MRI test typically lasts 30 to 60 minutes, depending on the type of information requested by your doctor. For the best quality image, you need to be as still as possible during the exam.

Nuclear Medicine

Nuclear medicine is a safe, painless, and effective form of medical imaging which has been used worldwide for more than 60 years. This area of radiology uses small amounts of radioactive material (sometimes called a dose) to image the body and treat disease. Nuclear medicine differs from other areas of radiology because it looks at how a body part is working, not just what it looks like.


PET/CTs are commonly used by doctors to determine whether a patient has cancer, if it's spreading, whether their treatment is working or if there's a recurrence. A PET/CT scan is noninvasive and painless. Along with providing better imaging data, it increases patient comfort and convenience by reducing the number of scanning sessions a patient must undergo.


Diagnostic X-ray encompasses many different types of exams such as bone imaging, chest X-rays, abdomen plain films, fluoroscopy and studies using contrast agents.


A handheld transducer, about the size of a bar of soap, is pressed against the skin. The transducer sends high-frequency sound waves into the body. The sound waves echo back from fluids and tissues to a computer, which measures and displays sound waves as a real-time picture.

Ultrasound is primarily used to evaluate the abdomen and pelvis to differentiate tumors from cysts, monitor a fetus and investigate issues in the gallbladder, ovaries and uterus.
