CT (computed tomography), also called a CAT scan, uses x-ray and computer equipment to produce cross-sectional images from of body issues and organs. CT imaging is useful because it can show several types of tissue, such as lung, bone, soft tissue and blood vessels.
Magnetic resonance imaging, or MRI, uses strong magnet and radio waves to provide clear and detailed diagnostic images of internal body organs and tissues. MRI is a valuable tool for the diagnosis of a broad range of conditions, including:
Positron emission tomography, also called a PET scan, is a nuclear medicine exam that produces a three dimensional image of functional processes in the body. A PET scan uses a small amount of a radioactive drug to show differences between healthy and diseased issue. The diagnostic images produced by PET are used to evaluate a variety of diseases.
X-ray is the oldest and most frequently used form of medical imaging. X-rays can produce diagnostic images of the human body on film or digitally that allow doctors to view and assess broken bones. X-rays are an important tool in guiding orthopedic surgery and in the treatment of sports-related injuries.
To accurately detect osteoporosis, doctors commonly use DEXA bone densitometry to measure bone mineral density (BMD). DEXA is a quick, painless procedure for measuring bone loss. Measurement of the lower spine and hips are most often done.
Mammography, also known as a mammogram, is the examination of the breast using x-rays. Mammography is considered the most effective tool for early breast tumor detection. State-of-the-art 3-D breast tomosynthesis is available and will be discussed with the patient at the time of the exam.
Ultrasound imaging, also called sonography, is a method of obtaining diagnostic images from inside the human body through the use of high frequency sound waves. Utrasonography is used as a diagnostic tool that can assist doctors with making recommendations for further treatment.
With the aid of a contrast agent, Fluoroscopy enables a x-ray technologist to capture an image of an internal body organ while it is functioning. This contrast agent allows the image to be viewed clearly on a monitor or screen.
Nuclear medicine, or scan, uses a small amount of a radioactive substance to produce two or three dimensional images of body anatomy and function. The diagnostic images produced by a nuclear scan are used to evaluate a variety of diseases. Sometimes a nuclear scan is combined with a CT scan.
Interventional radiologists (IRs) use their expertise in reading X-rays, ultrasound and other medical images to guide small instruments such as catheters (tubes that measure just a few millimeters in diameter) through the blood vessels or other pathways to treat disease percutaneously (through the skin).
