21
Q

What is the main risk of radiation?

A

22
Q

What are the benefits of radiation?

A

Diagnosis
Management Change
Treatment

23
Q

Why is technetium often used as a radionuclide?

A

It stays in an excited state for a long time.

24
Q

In a gamma camera, what is placed over the image crystal?

A

Collimator

25
Q

Why is there a lead shielding?

A

To stop gamma radiation getting out.

26
Q

How are gamma cameras used in SPECT and PET?

A

Cameras are rotated around the area being scanned, shooting gamma rays and detecting ones that get absorbed.
