About Diagnostic Radiology

 

 

General Radiography

Diagnostic Radiology offers many exams for virtually any part of the body. These exams are performed in an X-ray room and may consist of images of the chest, abdomen, skull, spine or extremities. At the time of the exam you will be asked to sit or lie on an X-ray table, and a technologist will position an X-ray machine over the part that is affected.

Fluoroscopy

Fluoroscopy is the method that provides real-time X ray imaging that is especially useful for guiding a variety of diagnostic and interventional procedures. The ability of fluoroscopy to display motion is provided by a continuous series of images produced at a maximum rate of 25-30 complete images per second. This is similar to the way conventional television or video transmits images.

Computed Tomography

Computed tomography (CT) scanning, also called computerized axial tomography (CAT) scanning, is a medical imaging procedure that uses x-rays to show cross-sectional images of the body.

A CT imaging system produces cross-sectional images or "slices" of areas of the body, like the slices in a loaf of bread. These cross-sectional images are used for a variety of diagnostic purposes.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) is an exam that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.

MRI also may show problems that cannot be seen with other imaging methods.

Nuclear medicine

Is a branch or specialty of medicine and medical imaging that uses radionuclides and relies on the process of radioactive decay in the diagnosis and treatment of disease.

In nuclear medicine procedures, elemental radionuclides are combined with other elements to form chemical compounds, or else combined with existing pharmaceutical compounds, to form radiopharmaceuticals. These radiopharmaceuticals, once administered to the patient, can localize to specific organs or cellular receptors. This property of radiopharmaceuticals allows nuclear medicine the ability to image the extent of a disease-process in the body, based on the cellular function and physiology, rather than relying on physical changes in the tissue anatomy. In some diseases nuclear medicine studies can identify medical problems at an earlier stage than other diagnostic exams.

Ultrasound

An ultrasound scan is a painless exam that uses sound waves to create images of organs and structures inside your body. It is a very commonly used exam. As it uses sound waves and not radiation, it is thought to be harmless.
