imaging techniques

Question 1

making of a motion picture of successive images appearing on a fluoroscopic screen

Answer 1

CINERADIOGRAPHY

Question 2

use of a computer to generate an image from a large number of x-rays passed at different angles through the body; a three dimensional picture of a cross-section of the body is obtained; reveals more tissue than does simple radiography

Answer 2

COMPUTED TOMOGRAPHY SCAN (CT-SCAN)

Question 3

use of x-rays to examine deep structures; the shadows cast by x-rays passed through the body are observed on a fluorescent screen; the device used is called fluoroscope

Answer 3

FLUOROSCOPY

Question 4

use of x-rays passed through the body to make a visual record (radiograph) of internal
structures on specially sensitized film

Answer 4

RADIOGRAPHY

Question 4

production of sectional body images by administration of a natural substance, such
as glucose, labeled with a positron-emitting isotope; the rays subsequently emitted are interpreted by computer to show the internal distribution of the substance administered; has been used to follow blood flow through an organ and to measure metabolic activity within an organ, such as the brain, under different conditions

Answer 4

POSITRON EMISSION TOMOGRAPHY (PET)

Question 4

production of an image of the distribution of radioactivity in tissues after internal administration of a radioactive substance (radionuclide); the images are obtained with a
scintillation camera; the record produced is a scintiscan (SIN-ti-skan) and usually specifies
the part examined or the isotope used for the test, as in bone scan, gallium scan

Answer 4

SCINTIGRAPHY

Question 5

production od images through the use of a magnetic field and radio waves; the characteristics of soft tissue are revealed by differences in molecular properties; eliminated the need for x-rays and contrast media

Answer 5

MAGNETIC RESONANCE IMAGING (MRI)

Question 6

scintigraphic technique that permits visualization of the cross-sectional distribution
of a radioisotope

Answer 6

SINGLE PHOTON EMISSION COMPITED TOMOGRAPHY (SPECT)

Question 7

generation of a visual image from the echoes of high-frequency sound waves traveling back from different tissues; also called sonography and echography

Answer 7

ULTRASOUND
