Reduction of the radiation
load
A.2
You can avoid repeating a measurement and so reduce the radi-
ation load on the patient by taking certain precautions.
A.2
✧ Inform the patient sufficiently. The patient must move as
little as possible during scanning and follow the breathing
instructions (to avoid motion artifacts).
✧ Ask the patient to remove all jewelry, hair clips, and so on
(to avoid metal artifacts).

medium can cause artifacts.

the manual.
