– For good diagnostics, high dose is OK!
– For screening, a worse idea…

7. Remarks Concerning
Diagnostic Reference Levels (1/3)

• Beware: the trains will run today!
– On the other hand, no alert was given in

8. Remarks Concerning
Diagnostic Reference Levels (2/3)
• Strict EU directives on RF exposure:
– No MRI intervention
– CT intervention instead
– Silly!
• So, beware of too strict regulations!
• Better good diagnostics than low dose!

9. Remarks Concerning
Diagnostic Reference Levels (3/3)
• Leg je de lat te hoog…
– Dan ga je er aan onder door
• Leg je de lat te laag…
– Dan struikel je er over
