What is the German requirement for radiographic justification?
In Germany, the rechtfertigende Indikation is the qualified decision whether and how an application of ionising radiation is medically justified. The health benefit of the individual examination must outweigh its radiation risk. This decision is made before exposure.

A specific clinical question
Symptoms and examination establish a diagnostic question. Imaging must offer expected benefit for that question; wanting an image alone does not justify exposure.
A qualified decision
A doctor or dentist with the required radiation-protection qualification makes the decision. A referral does not remove this duty. Both whether and how to perform the examination are assessed.
Use existing information
Relevant previous images and medical findings are considered. They may show that an existing image suffices or that another examination would be more suitable.

Often confused
Patient preference or indication?
A preference explains what someone wants to achieve. Radiographic justification assesses whether the particular exposure is medically warranted for that purpose.
Quick answers
Does a referral replace justification?
No. Section 119 of the German Radiation Protection Ordinance requires justification even when another doctor or dentist requests the examination.
Can my consent justify any X-ray?
No. Consent and professional benefit-risk assessment serve different purposes. The qualified decision remains necessary.
Does this apply to digital images?
Yes. What matters is the use of ionising radiation, not whether images are recorded on film or digitally.

Make the distinction
A preference explains what someone wants to achieve. Radiographic justification assesses whether the particular exposure is medically warranted for that purpose.
