1

radiology

medical specialty concerned with the study of xrays and other imaging technologies to produce or interpret images for diagnosis of disease

2

x rays

invisible waves of energy

3

nuclear medicine

use of radioactive substances in the diagnosis of disease

4

Types of diagnositic techniques

digital radiography
computed tomography (CT)
contrast studies (take a picture with a fluid going through the system)
fluoroscopy
interventional radiology
ultrasound
MRI

5

lateral decubitus

lying down on the side

6

prone

lying on the belly (face down)

7

recumbent

lying down (belly or back)

8

supine

lying on back face up

9

radionuclides/radioisotopes use

alpha, beta and gamma rays

10

half life

the times required to lose half of its radioactivity

11

in vitro procedures (test tube)

analysis of blood and urine
uses radioactive chemicals and antibodies to detect hormones

12

In vivo procedures (body)

radioactive substance given directly to patient to evaluate organ function or image

13

gamma camera

machine to detect gamma rays emitted from radiopharmaceuticals

14

gamma rays

high energy rays emitted by radioactive substances in tracer studies

15

interventional radiology

therapeutic or diagnostic procedures performed be radiologist

16

radiolabeled compound

used in nuclear medicine studies

17

radiolucent

permitting the passage of x rays

18

radiopaque

obstructing the passage of x rays

19

SPECT

radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a composite of many views

22

is/o

same

23

echo-

repeated sound
