Magnetic Resonance Imaging (or MRI)

MRI has become widely accepted as the standard diagnostic tool for a wide and fast-growing variety of clinical applications for soft tissue anatomy (as found in the brain, spinal cord and interior ligaments of body joints such as the knee). MRI uses a strong magnetic field in conjunction with low energy electromagnetic waves that are processed by a computer to produce high-resolution, three-dimensional, cross-sectional images of body tissue, including the brain, spine, abdomen, heart and extremities. MRI systems can have either open or closed designs and routinely have magnetic field strength of 0.2 Tesla to 3.0 Tesla.

Computed Tomography (or CT)

CT provides higher resolution images than conventional X-rays, but generally not as well-defined as those produced by MRI. CT uses a computer to direct the movement of an X-ray tube to produce multiple cross-sectional images of a particular organ or area of the body. CT is used to detect tumors and other conditions affecting bones and internal organs. It is also used to detect the occurrence of strokes, hemorrhages and infections.

Positron Emission Tomography (or PET)

PET scanning involves the administration of a radiopharmaceutical agent with a positron-emitting isotope and the measurement of the distribution of that isotope to create images for diagnostic purposes. PET scans provide the capability to determine how metabolic activity impacts other aspects of physiology in the disease process by correlating the reading for the PET with other tools such as CT or MRI. PET technology has been found highly effective and appropriate in certain clinical circumstances for the detection and assessment of tumors throughout the body, the evaluation of some cardiac conditions and the assessment of epilepsy seizure sites. The information provided by PET technology often obviates the need to perform further highly invasive and/or diagnostic surgical procedures.

Nuclear Medicine

Nuclear medicine uses short-lived radioactive isotopes that release small amounts of radiation that can be recorded by a gamma camera and processed by a computer to produce an image of various anatomical structures or to assess the function of various organs such as the heart, kidneys, thyroid and bones. Nuclear medicine is used primarily to study anatomic and metabolic functions.

Diagnostic Radiology (or X- ray)

X- rays use roentgen rays to penetrate the body and record images of organs and structures on film. Digital X-ray systems add computer image processing capability to traditional X-ray images.

Ultrasound

Ultrasound imaging uses sound waves and their echoes to visualize and locate internal organs. It is particularly useful in viewing soft tissues that do not X-ray well. Ultrasound is used in pregnancy to avoid x-ray exposure as well as in gynecological, urologic, vascular, cardiac and breast applications.

Mammography

Mammography is a specialized form of radiology using low dosage X-rays to visualize breast tissue and is the primary screening tool for breast cancer. Mammography procedures and related services assist in the diagnosis of and treatment planning for breast cancer.

Fluoroscopy

Fluoroscopy uses ionizing radiation combined with a video viewing system for real time monitoring of organs.
