radiography | use of x-rays passed through the body to make a visual record of internal structures on specially sensitized film |
fluoroscopy | use of x-rays to examine deep structures by observing the shadows cast by x-rays passed through the body on a fluorescent screen |
cineradiography | making of a motion picture of successive images appearing on a fluoroscopic screen |
computed tomography | use of a computer to generate an image from a large number of x-rays passed at different angles throught the body. a 3D picture of a cross-section of the body is obtained |
ultrasonography | generation of a visual image from the echoes of high frequency sound waves traveling back from different tissues (AKA: sonography and echography) |
scintigraphy | production of an image of the distribution of radioactivity in tissues after internal administration of a radioactive substance (radionuclide), it usually specifies the part examined or the isotope used for the test, ie; bone scan |
magnetic resonance imaging | production of images through the use of a magnetic field and radiowaves eliminating the need x-rays and contrast media (AKA: MRI) |
positron emission | production of sectional body images by administration of a natural substance (like glucose) labeled with a positron-emitting isotope, a computer interprets the rays emitted to show the internal distribution of the substance. can be used to measure metabolic activity within an organ, or blood flow, etc. (AKA: PET) |
