Flashcards in Imaging in inflammatory disorders and infections Deck (10):
1

What is the properties of the ideal isotope

Similar half life to length of procedure
Gamma emitter
Easily bound to pharmaceutical component
Energy of gamma rays should be 50-300 keV

2

What happens in a tomography gamma camera

Nuclear energy, gamma rays being emitted from patient is picked up and image crystal produces flash of light and electrical energy converts it into a picture

3

What does image quality depend on in a tomography gamma cameras

Radiation dose
Metal objects
Proximity to camera

4

Define scintagraphy

radioactive tracer used to obtain image of body organs / functions

5

What is a common radionuclide

99mTc

6

What is SPECT

Single-photon emission computed tomography is a nuclear medicine tomographic imaging technique using gamma rays

7

What is PET

Molecular imaging as inject/inhale radioactive drug tracer to show activity of organs/ tissues

8

example of radioactive tracer in PET scan

18F-fluorodeoxy glucose

9

Main risk of ionising radiation

Induce cancer

10

Define CT

X-rays produce a digital image of a slice of tissue, usually in an axial plane using computing to create the image
