Radiology and Diagnostic Imaging Terms
The following is a list of some common radiology and diagnostic imaging terms. This Glossary may help you understand what your physician has explained and may help you understand your medical records.
X-ray (radiograph or plain film)
X-rays or lights with high energy are shined through a body part. These rays are then broadcast either onto film or to a receiver if the system is digital. Different tissues absorb different amounts of radiation depending upon density. For example, bone absorbs more radiation than does muscle or skin. Therefore, bone will appear white or light and less dense tissues such as muscle, colon, lung, etc. will appear dark. A simple example is an x-ray to diagnosis a fracture. The solid bone will appear white and the fracture will appear dark because more radiation will slide through the fracture site.
Magnetic Resonance Imaging
Magnetic Resonance Imaging or MRI takes advantage of the magnetic properties of hydrogen atoms in the body. An MRI machine uses magnets and radio waves. Sometimes contrast is used to enhance MRI. MRI is useful for evaluating central nervous system issues, issues in the chest and abdomen, musculoskeletal systems and contrast enhanced MRI is helpful in evaluating infection, brain issues, tumors, etc.
Ultrasound
Ultrasound uses sound waves to produce images. A component called a transducer generates high frequency sound which is broadcast through the skin and the body. It returns to a receiver and the data are combined to produce an image. Ultrasound is often used for evaluating unborn children, and issues with organs such as kidneys, gallbladders and livers.
Computed Tomography
Computed tomography is also known as CAT Scan or C-T Scan. CAT Scans evaluate body parts by generating cross-section views of specific body parts. Sometimes radiologists will use intravenous iodinated contrast materials to evaluate specific organs. Contrast may also be injected into specific body parts to assist in obtaining cross-section images. Generally, contrast is safe. However, there are occasionally allergic type reactions. Often, reactions require no treatment. However, reactions can be life threatening.such as anaphylaxis.
Fluoroscopy
Fluoroscopy utilizes a continuous beam of x-ray radiation to generate a moving picture image which is viewed on a computer monitor. Fluoroscopy can assist in evaluating issues with moving joints, gastrointestinal issues, lung or diaphragm abnormalities or swallowing issues. Fluoroscopy is also used during the placement of needles to make sure that needles are located in the appropriate anatomical position.
