Radiology and Nuclear Medicine terms

computed tomography, beams x-rays at multiple angles through a section of the patient's body

magnetic resonance imaging, magnetic field and radio waves produce sagittal, coronal, and axial images of the body

positron emission tomography, positron-emitting radiactive substances given intravenously create a cross-sectional image of cellular metabolism based on local concentration of the radioactive substance

ultrasonography, diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body

single photon emission computed tomography, radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a composite of many views

an x-ray procedure that makes it possible to see internal organs in motion

process, test, or procedure is performed, measured, or observed outside a living organism, often in a test tube

process, test or procedure is performed, measured, or observed within a living organism

permitting the passage of x-rays, radiolucent structures appear black on x-ray film

obstructing the passage of x-rays, radiopaque structures appear while on the x-ray film

phosphate compound is taken up preferentially by bone and the skeleton is imaged in 2 or 3 hours, the scan detects infection, inflammation, or tumors involving the skeleton, which appear as areas of high uptake on the scan

radiopaque materials (contrast media) are injected to obtain contrast with surrounding tissue when shown on the x-ray film

time required for a radioactive substance to lose half its radioactivity by disintegration

therapeutic or diagnostic procedures performed by a radiologist

transformation of electrically neutral substances into electrically charged particles

radionuclides are used as tags or labels, attached to chemicals and followed as they travel through the body

handheld device that sends and receives ultrasound signals

diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body

different views of x-ray
