A radioactive form of an element. Top/o means place; isotopes of an element have similar structures but different weights and stability. A radioisotope (radionuclide) is an unstable form of an element that emits radioactivity.
Radioactive drug (radionuclide plus a drug) that is administered safely for diagnostic and therapeutic purposes. In this term, radi/o stands for radioactive.
One who assists a radiologist in performing diagnostic x-ray procedures.
Study of x-ray and other energy sources in the diagnosis of disease.
Record of sound waves within the uterus (after injection of saline solution through a catheter inserted into the vagina and cervical canal to the uterus to distend the uterine cavity, which is then examined by ultrasound imaging.
treatment or therapy
Pertaining to treatment or therapy.
Experiments performed in a test tube (glass); outside of a living organism.
Experiments performed within a living organism.
The international unit of x- or γ-radiation; it is the quantity of x- or γ-radiation such that the associated corpuscular emission per 0.001293 g of dry air produces in air ions carrying 1 electrostatic unit of electrical charge of either sign. Symbol R.
Record (x-ray) of blood vessels.
Record (x-ray) of the uterus and fallopian tubes.
Record (x-ray) of the renal pelvis of the kidney.
process of recording
Process of recording x-ray images of the body in a cross-sectional view; a computer is used and images taken all around a section of the body. Tom/o means to cut, as in viewing in slices.
Permitting the passage of x-rays (rays shine through). Radiolucent (indicating that x-rays pass through easily) areas on x-ray images appear dark.
Obscuring or obstructing the passage of x-rays. Radiopaque (indicating that x-rays do not penetrate) areas on x-ray images appear white/light.
a repeated sound
Process of recording sound waves (echoes) as they bounce off the heart; a picture is produced ahat shows the sound waves as they are reflected from tissues of different densities.
Process of using ultrasound waves in the body to produce sound echoes that are recorded as an image. Sound waves are beyond the normal range of those that a human can hear.
ion; to wander
