1

is/o

same

2

radioisotope (radionuclide)

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.

3

pharmaceut/o

drug

4

radiopharmaceutical

Radioactive drug (radionuclide plus a drug) that is administered safely for diagnostic and therapeutic purposes. In this term, radi/o stands for radioactive.

5

radi/o

x-rays

6

radiographer

One who assists a radiologist in performing diagnostic x-ray procedures.

7

radiology

Study of x-ray and other energy sources in the diagnosis of disease.

8

son/o

sound

9

hysterosonogram

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.

10

therapeut/o

treatment or therapy

11

therapeutic

Pertaining to treatment or therapy.

12

vitr/o

glass

13

in vitro

Experiments performed in a test tube (glass); outside of a living organism.

14

viv/o

life

15

in vivo

Experiments performed within a living organism.

16

roentgen/o

x-rays

17

Roentgen

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.

18

-gram

record

19

angiogram

Record (x-ray) of blood vessels.

20

hysterosalpingogram

Record (x-ray) of the uterus and fallopian tubes.

21

pyelogram

Record (x-ray) of the renal pelvis of the kidney.

22

-graphy

process of recording

23

computed tomography

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.

24

-lucent

to shine

25

radiolucent

Permitting the passage of x-rays (rays shine through). Radiolucent (indicating that x-rays pass through easily) areas on x-ray images appear dark.

26

-opaque

obscure

27

radiopaque

Obscuring or obstructing the passage of x-rays. Radiopaque (indicating that x-rays do not penetrate) areas on x-ray images appear white/light.

28

echo-

a repeated sound

29

echocardiography

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.

30

ultra-

beyond

31

ultrasonography

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.

32

ion/o

ion; to wander

33

myel/o

spinal cord; bone marrow
