How Does Imaging Technology Work?

Radiology uses a Picture Archiving Communication System (PACS) to create a "filmless environment" that allows all acquired medical imaging to be reviewed and stored electronically. This provides more efficient and timely processes in diagnosing pathology and allowing clinicians the ability to communicate quickly for treatment planning.

64-Multi-detector CT Scanner technology takes an image of the body structure—bone, vessels, muscle, skin—and its images are transferred into 3-D for a highly realistic view. This technology is extremely quick and highly accurate, and is an important aid in assessing complex traumas, as well as ruling out certain cardiac diagnoses.

Magnetic resonance imaging (MRI) uses radiofrequency waves and a strong magnetic field, rather than x-rays, to provide remarkably clear and detailed pictures of internal organs and tissues. The technique has been proven very valuable for the diagnosis of a broad range of pathologic conditions in all parts of the body including cancer, heart and vascular disease, stroke, and joint and musculoskeletal disorders.

Nuclear Medicine uses radioactive isotopes to seek out and identify or treat disease areas that may not be detected with other diagnostic tests. Nuclear Medicine is considered safe, painless, and effective because it provides doctors with information about both bodily structure and function. It is a revolutionary way to gather medical information that complements other imaging technologies. Nuclear medicine imaging procedures often identify abnormalities very early on in the progress of a disease—long before many medical problems are apparent with other diagnostic tests.

Angiography is the imaging of blood vessels in the body with the use of injected x-ray "dye" and rapid sequence imaging. Applications of this type of imaging are utilized throughout the body for diagnosis and treatment.

CAD (computer aided detector) is an assisted screening device system that identifies and marks "areas of interest" on routine screening and diagnostic mammograms, and brings these areas to the radiologist's attention at the same time as the initial reading is completed. This system assists the radiologist to lessen observational oversights by identifying areas on the original mammograms that may need additional studies. Reportedly, the CAD increases the sensitivity of finding early breast cancers by 20 percent.
