On the basis of section 84 (2) of the Radiation Protection Act (Strahlenschutzgesetz), as last amended by Article 248 no. 1 of the Eleventh Competence Adjustment Ordinance (Elfte Zuständigkeitsanpassungsverordnung) of 19 June 2020 (Federal Law Gazette I, p. 1328), in conjunction with section 1 (2) of the Competence Adjustment Act (Zuständigkeitsanpassungsgesetz) of 16 August 2002 (Federal Law Gazette I, p. 3165) and the organisational decree of the Federal Chancellor of 8 December 2021 (Federal Law Gazette I, p. 5176), the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection orders as follows:

table of contents

Section 1
Definitions

(1) ‘Low-dose computed tomography’ means a computed tomography of the thorax in which, in order to achieve the image quality required for lung cancer screening,

1.  a volume computed tomography dose index of 1.3 milligrays is not exceeded or

2.  a volume computed tomography dose index greater than 1.3 milligrays is necessary in the individual case due to the physical build of the person to be examined.

The volume computed tomography dose index of the associated localiser radiograph is not included in the volume computed tomography dose index of the low-dose computed tomography.

(2) ‘Packet year’ means the unit in which cigarette consumption is stated. To determine cigarette consumption in packet years, for each year of cigarette consumption the average number of cigarettes smoked per day in that year is divided by 20. The results for the individual years calculated in accordance with sentence 2 are totalled. Cigarette consumption before a complete break from smoking is to be included only if the complete break amounts to less than 10 years.

(3) ‘Software for computer-assisted detection’ means a computer program which assists medical doctors in the diagnostic review of computed tomography scans by analysing the digital image data.

(4) ‘A result in need of monitoring’ means a result in relation to an asymptomatic individual within the meaning of section 5 (16) of the Radiation Protection Act on the basis of which a further lung cancer screening examination within 12 months is medically indicated without any concrete suspicion of disease existing.

‘(5) A result in need of diagnosis’ means a result suggesting a lung carcinoma to such a strong degree that a concrete suspicion of disease exists and a prompt clinical diagnosis is called for.

Section 2
Permissibility of lung cancer screening examinations

(1) Lung cancer screening examinations using low-dose computed tomography are permitted in the case of persons

1.  who have completed their 50th but not their 76th year of life,

2.  whose last lung examination using computed tomography which was appropriate in qualitative terms for a diagnostic review in relation to a lung carcinoma took place at least 12 months ago,

3.  who are in possession of a report from a person fulfilling the requirements of section 6 (3) from which the following is apparent:

a)  cigarette consumption

aa)  for a period of at least 25 years, calculated on the basis that the years before a complete break from smoking and the years of the complete break itself are only included if the break amounts to less than 10 years, and

bb)  of at least 15 packet years and

b)  a medical suitability profile of the person to be examined and the relevant anamnestic data and

4.  who have been informed by a person fulfilling the requirements of section 6 (3) in an oral consultation and through the provision of information in text form of the following:

a)  the benefits of the lung cancer screening examination,

b)  the possibility that the lung cancer screening examination may produce false positive and false negative results and the possible consequences of this,

c)  the subsequent diagnostic procedure in the event of a result in need of diagnosis, in particular of the risks and burdens of the diagnostic examinations and

d)  the risk of overdiagnosis and overtreatment.

The information in text form must also draw attention to the radiation risk. Other obligations to provide information in accordance with public or private law remain unaffected.

(2) Following a result in need of monitoring, in derogation from subsection (1) sentence 1 no. 2, a lung cancer screening examination using low-dose computed tomography is permissible before the expiry of 12 months.

Section 3
Justifying indication

The radiation protection executive must ensure that a person who fulfils the requirements of section 6 (1)

1.  verifies the conditions for permissibility as referred to in section 2 and

2.  provides the justifying indication in accordance with section 83 (3) of the Radiation Protection Act for the lung cancer screening examination for the person to be examined having due regard to the report as referred to in section 2 (1) sentence 1 no. 3.

Section 4
Requirements for computed tomography scanners, diagnostic workstations, performance of examinations and software for computer-assisted detection

(1) The requirements for computed tomography scanners, diagnostic workstations, performance of examinations and software for computer-assisted detection follow from the annex to this Ordinance. The radiation protection executive must ensure that the requirements are observed.

(2) If the person to be examined has already undergone a lung cancer screening examination, the radiation protection executive must ensure that before a computed tomography scan is produced

1.  the computed tomography scans, including the associated results acquired in the two most recent lung cancer screening examinations, are to hand or

2.  if only one lung cancer screening examination has previously taken place, the computed tomography scan, including the associated results of the last lung cancer screening examination, is to hand.

If it is not possible to produce the documents or this would result in a disproportionate effort for the radiation protection executive, the requirement to have the documents to hand may be waived in an individual case.

table of contents

Section 5
Diagnostic review of the examination

(1) The radiation protection executive must ensure that a person fulfilling the requirements of section 6 (1) reviews the computed tomography scan first without and then making use of software for computer-assisted detection (first reviewer).

(2) If the first reviewer concludes that the result constitutes a result in need of monitoring or in need of diagnosis, then the radiation protection executive must ensure that an additional person who fulfils the requirements of section 6 (2) reviews the computed tomography scan independently of the first reviewer first without and then making use of software for computer-assisted detection (second reviewer).

(3) The radiation protection executive must ensure that following the diagnostic review in accordance with subsection (2) a final joint assessment of the computed tomography scan is provided by the first and second reviewers. If the joint assessment concludes that the result constitutes a result in need of monitoring, a joint recommendation is to be made on the timing of the next lung cancer screening examination.
