European foreword
This document (prEN 18167:2025) has been prepared by Technical Committee CEN/TC 470 “Quality
along the patient pathway in medical imaging”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
prEN 18167:2025(E)
Introduction
This document deals with quality in diagnostic and interventional Radiology practiced in Radiology
services.
The medical speciality Radiology is also known as Radiology and Medical Imaging and is referred to as
Medical Imaging (MI) throughout this document. It is exercised within a multi professional team
consisting of radiologists, radiographers and other professionals related to the context and the
complexity of the examinations.
This quality management standard refers to all diagnostic and interventional methods in MI especially
using X-rays, ultrasonography, and magnetic resonance imaging (MRI).
All healthcare professionals also using such imaging techniques are invited to adopt the standard.
MI activities are exercised for preventive, diagnostic, therapeutic, surveillance and follow-up purposes.
As is the case for all healthcare services, the objectives of MI activities are to provide patient care that is
appropriate, compliant with the current standards, with controlled risks that are announced,
understood as far as possible and accepted by the patient, for the correctly identified person, accessible
to all, taking the patient’s expectations into account and administered with care.
Obviously, MI extends beyond the mere production of images or the performance of a procedure, and
includes, in particular, all opinions or discussions on the justification and optimization of such
procedures, and their use in the subsequent management of patients.
This document enables peer assessment, through external peer audits, of the quality and competences
of an MI Organization to perform MI procedures. Conformity with this document aims to ensure the
appropriateness and quality of the procedures and patient care, and the safety of practices. It enables
professionals to improve their practices, while still having the time and energy for proper management
of patients.
Meeting the prevailing statutory and regulatory requirements of the prevailing jurisdiction is an
essential prerequisite.
This document was written according to the principle of a process-based approach, by presenting the
support processes first, then the patient management processes and finally the quality management
system, including assessments.

4 Background information
4.1 Which healthcare services are concerned?
MI covers diagnostic imaging and interventional imaging.
MI diagnostic procedures deliver morphological and/or functional and/or metabolic information on the
human body. MI interventional procedures have investigational or therapeutic objectives and are
guided and monitored by imaging.
The corresponding procedures are performed on humans, from foetuses to the elderly, including
postmortem procedures.
MI activities are medical procedures. Their main steps are: the analysis and approval of the imaging
referral for the purposes of justification; scheduling; the prescription of the medicine required for the
MI procedure, where necessary; the preparation and performance of the MI procedure, including its
optimization; image processing if necessary and the production and delivery of the report. The MI
procedure is associated with pre- and post-procedure assessments and discussions, which, in
particular, may be multidisciplinary.
The healthcare services concerned call on all the skills and organizations required to perform these MI
procedures.
The MI Organization itself, or the healthcare organization which it belongs to, is responsible for meeting
the requirements of this document.
4.2 Where are these healthcare services provided?
MI procedures are performed in imaging departments and imaging centres, hereafter referred to as MI
organizations. Procedures performed by MI professionals, outside these locations, e.g. in operating
suites or by the use of mobile units, are also part of the scope.
These MI organizations are independent and autonomous, or part of a healthcare organization.
The MI Organization can have one or more sites belonging to the same public, private or mixed legal
entity. It can be associated with other healthcare organizations.
The MI Organization can be in healthcare units in specific environments (detention centres, or others).
However, facilities which do not administer any patient care, are outside the scope of this document.
prEN 18167:2025(E)
4.3 Who performs the procedures defined in this document?
The healthcare professionals who collaborate in the MI Organization do so within a team. The team
includes two key categories of licensed professionals: the radiologist, who is a physician specialized in
Radiology, and the radiographer. They work in a complementary manner according to their respective
qualification, training and entitlement, the techniques employed, the situations encountered, as well as
with national regulations and their developments.
Along the patient pathway some activities require specific competences (such as those related to safety
or mastery of certain examinations) which require specific qualifications. For this reason, and without
aiming to be exhaustive, in paragraph 5.7.2. reference is made to the roles of the Medical Physics Expert
(MPE) and of the Radiation Protection Officer (RPO), in paragraph 5.8.2 to the roles of the MR Medical
Director (MRMD), MR Safety Officer (MRSO), MR Safety Expert (MRSE) and in paragraph 7.4. to the role
of the quality manager.
NOTE 1 The MI team includes:
—non-radiologist doctors who work in the MI Organization and adopt this document.
—the professionals providing the support functions required to exercise the main activity.
—all those in training.
NOTE 2 The authorized health care professional also called the referrer who asks for the examination is not
part of the MI team.
4.4 Who can access the healthcare services concerned?
The healthcare services concerned can be accessed by the entire prenatal, child and adult population
likely to suffer from a health disorder (exploratory phase), with a health disorder (additional diagnosis,
treatment using MI, regular monitoring or in the case of possible complications), or subject to
screening.
The activities of MI organizations are scheduled or performed in emergencies, for both hospitalized
patients and outpatients.
Each MI Organization defines the types of MI procedures it performs and for which populations.
4.5 What are the characteristics of these healthcare services?
The objective is that the management of patients be administered with due quality and safety, in
accordance with the regulations and the recommendations on best-medical practices, including risk
management.
The internal rules of the organization comply with applicable regulations and recommendations.
Information, consent and the protection of professional confidentiality comply within the values,
obligations and rules of the healthcare professions and of other professionals who participate in the
activity of the MI organization, in accordance with the applicable regulations.
MI procedures involve the use of equipment and, in particular, of medical image acquisition devices
(CT scanners, magnetic resonance imaging (MRI), fixed or mobile radiography and radioscopy
equipment, ultrasonic scanners, hybrid devices, etc.), the use of other medical devices, which may be
implantable or not, and of medicines including contrast agents.
prEN 18167:2025(E)
The MI procedure implements the principles of justification and optimization, whether it uses ionising
radiation or not. The operational implementation of the principle of justification consists of choosing
the right procedure for the right patient, as described in “6.1 Imaging referrals for MI procedures” and
“6.2 Justification and approval of the imaging referral”. The adoption of the principle of optimization by
the professionals involved aims to limit the doses of exposure to ionising radiation and electromagnetic
waves for the exposed persons, and the doses of contrast agents administered, while guaranteeing the
adequate diagnostic quality of the examination.
Medical activity is usually conducted face to face, but it can also be exercised remotely (e.g. by
teleradiology) under conditions defined by regulations and procedures. In this case, the assessment of
the MI organization includes the procedures performed on-site and the procedures performed
externally/remotely under the organization’s control, and in particular their relevance and
optimization.
All the activities are exercised in accordance with the patient’s rights.
4.6 When do the rules outlined in this document apply?
This document applies to the medical activity of the MI Organization at all times.
5 Technical medical requirements
5.1 General
The MI Organization shall control the processes and risks related to the pathway and care of the patient
and the performance of the MI procedures. The performed MI procedures are defined by the MI
organization.
5.2 Human resources
5.2.1 General
The MI Organization shall determine and ensure that its workforce possesses the skills required for
safety, effectiveness, proper patient management of patients and a strong command of the MI
procedures that it performs. To this end, it shall determine and provide the necessary human resources
for the implementation of its quality management system (QMS).
