Continual advances in technology have led to the increasing use of ionising radiation in many patient pathways. The benefits of using ionising radiation for diagnosis and treatment need to be weighed against the risks associated with the detrimental effects of the radiation dose. Regulations provide a framework for the safe use of ionising radiation in medical and non-medical imaging using medical radiological equipment. Guidance is required to help interpret these regulations. The Ionising Radiation (Medical Exposures) Regulations 2017 and Ionising Radiation (Medical Exposure) Regulations (Northern Ireland) 2018 came into force on 6 February 2018 replacing IR(ME)R 2000 and the Medicines (Administration of Radioactive Substances) Regulations 1978. The updated regulations retain the four duty holders identified in IR(ME)R 2000: the employer, referrer, practitioner and operator. The responsibilities of each duty holder are defined in the regulations. The principles of justification, optimisation and adequate training of practitioners and operators remain fundamental to the updated regulations, with some new requirements included. This guidance seeks to explain how the requirements of the regulations should be interpreted and used in practice. It explains the principles and requirements of IR(ME)R, providing clinical scenarios to enable practical interpretation of the regulations. This document has been written in support of all staff groups involved in medical and non-medical exposures within clinical settings, both in the NHS and the independent sector, research laboratories, universities and sports facilities, where appropriate. This guidance also applies to those services using ionising radiation outside of radiology and nuclear medicine departments such as cardiology and orthopaedics. Specific guidance is available for dental exposures and therefore is not covered in this guidance. The inclusion of diagnostic nuclear medicine into this document complements the updated radiotherapy IR(ME)R guidance, which now includes molecular radiotherapy. Every effort has been made to provide a consistent approach across the two guidance documents with shared working across the disciplines of diagnostic imaging, nuclear medicine and radiotherapy. This guidance has been produced by a working party, which included representatives from: § British Institute of Radiology § British Society of Paediatric Radiology § Institute of Physics and Engineering in Medicine § Medical Exposures Group, Public Health England § Royal College of Radiologists § Society and College of Radiographers www.rcr.ac.uk IR(ME)R 4 Implications for clinical practice in diagnostic imaging, interventional radiology and diagnostic nuclear medicine We would like to thank members of the working party (Appendix 8) for their time and expertise in developing this document and acknowledge the radiotherapy IR(ME)R working party for their contribution and shared working. Particular thanks should go to Dr Peter Riley, who chaired the working party. Sadly, Peter passed away during the later stages of the development of this document. The radiology community owe him a great debt for this document. In recognition of all his valuable work as an interventional radiologist and on radiation safety the RCR has issued this document in memoriam to Dr Riley. We hope this document will support the diagnostic and nuclear medicine communities to implement IR(ME)R in their practice. Stewart Redman Radiation Protection Adviser to The Royal College of Radiologists www.rcr.ac.uk IR(ME)R 5 Implications for clinical practice in diagnostic imaging, interventional radiology and diagnostic nuclear medicine 1. This guidance document is intended to provide a practical approach to implementing Introduction the Ionising Radiation (Medical Exposure) Regulations 2017 (IR(ME)R) for all staff groups delivering a range of diagnostic imaging, interventional radiology and diagnostic nuclear medicine services.1 This guidance also applies to the implementation of the Ionising Radiation (Medical Exposure) Regulations (Northern Ireland) 2018 and any reference to ‘IR(ME)R’ can be taken to refer to these regulations also, unless specifically stated.2 Within the UK responsibility for healthcare is devolved and different approaches may be taken in each of the four nations. Typical scenarios and examples have been included within text boxes to provide practical advice on aspects of the regulations. These are taken from information provided to the working party by several hospital trusts or health boards and are not intended to be prescriptive. A glossary of terminology used in this guidance is included in Appendix 1. The Regulations IR(ME)R implements the medical exposure provisions from the European Council Basic Safety Standards Directive 2013/59/Euratom (BSSD).3 The BSSD takes into account the recommendations from the International Commission on Radiological Protection (ICRP) publication 103.4 IR(ME)R includes new requirements relating to the following: § Reporting of accidental and unintended exposures (Chapter 21) § Introduction of non-medical imaging exposures using medical radiological equipment which replaced and expanded upon medico-legal exposures (Chapter 18) § Introduction of a formal recognition scheme for medical physics experts (Chapter 19) § Introduction of licensing for employers and practitioners for the administration of radioactive substances to persons for diagnosis, treatment or research (Chapter 22) § Existing equipment requirements moved from the Ionising Radiations Regulations 1999 and new equipment requirements from BSSD added (Chapter 20).5 IR(ME)R places obligations on specific duty holders and provides a framework intended to protect individuals from the hazards associated with medical and non-medical exposures involving ionising radiation. The responsibility for compliance with IR(ME)R lies with the employer and each of the entitled duty holders. The roles and responsibilities of all duty holders are explained in Chapter 2 (Duty holder roles and responsibilities). IR(ME)R applies to medical exposures and specific types of non-medical exposures listed in Table 1.1 [Regulation 3]. www.rcr.ac.uk IR(ME)R 6 Implications for clinical practice in diagnostic imaging, interventional radiology and diagnostic nuclear medicine Table 1.1: Types of exposure Exposure Examples Medical exposures § Patients, as part of their medical § X-ray imaging, computed diagnosis or treatment tomography (CT), fluoroscopy, interventional radiology, dual- energy X-ray absorptiometry (DXA), mammography § Nuclear medicine imaging, positron emission tomography/computed tomography (PET-CT), non-imaging nuclear medicine examinations § Individuals as part of health § Imaging a group or population for a screening programmes disease (eg, NHS Breast Screening Programme) § Individuals participating in research § Patients taking part in clinical trials programmes § Carers and comforters § Individuals who provide support and comfort to a patient within a controlled or a supervised area (where access is normally restricted, or systems of work are in place to exclude members of the public) § Asymptomatic individuals § Investigations to exclude disease on individuals with no symptoms Non-medical exposures § Individuals undergoing non-medical § Health assessment for employment, imaging using medical radiological immigration or insurance purposes equipment § Radiological age assessment § Identification of concealed objects within the body This document should be read in conjunction with IR(ME)R and other published guidance.6 www.rcr.ac.uk IR(ME)R 7 Implications for clinical practice in diagnostic imaging, interventional radiology and diagnostic nuclear medicine 2.

  • Five-Year Results of a Merger Between Vascular Surgeons and Interventional Radiologists in a University Medical Center
    From the Eastern Vascular Society Five-year results of a merger between vascular surgeons and interventional radiologists in a university medical center Richard M. Green, MD, and David Waldman, MD, PhD, for the Center for Vascular Disease* Rochester, NY Objectives: We examined economic and practice trends after 5 years of a merger between vascular surgeons and interventional radiologists. Methods: In 1998 a merger between the Division of Vascular Surgery and the Section of Interventional Radiology at the University of Rochester established the Center for Vascular Disease (CVD). Business activity was administered from the offices of the vascular surgeons. Results: In 1998 the CVD included five vascular surgeons and three interventional radiologists, who generated a total income of $5,789,311 (34% from vascular surgeons, 24% from interventional radiologists, 42% from vascular laborato- ries). Vascular surgeon participation in endoluminal therapy was limited to repair of abdominal aortic aneurysms (AAAs). Income was derived from 1011 major vascular procedures, 10,510 catheter-based procedures in 3286 patients, and 1 inpatient and 3 outpatient vascular laboratory tests. In 2002 there were six vascular surgeons (five, full-time equivalent) and four interventional radiologists, and total income was $6,550,463 despite significant reductions in unit value reimbursement over the 5 years, a 4% reduction in the number of major vascular procedures, and a 13% reduction in income from vascular laboratories. In 2002 the number of endoluminal procedures increased to 16,026 in 7131 patients, and contributions to CVD income increased from 24% in 1998 to 31% in 2002. Three of the six vascular surgeons performed endoluminal procedures in 634 patients in 2002, compared with none in 1998.

  • About Interventional Radiology
    FACT SHEET Contact Maryann Verrillo, (703) 460-5572 Ellen Acconcia, (703) 460-5582 Nonsurgical Interventional Radiology Procedures Offer Less Risk, Less Pain and Less Recovery Time Compared to Open Surgery What Is Interventional Radiology? The landscape of medicine is constantly changing, and for the past 30 years, interventional radiologists have been responsible for much of the medical innovation and development of the minimally invasive procedures that are commonplace today. Interventional radiologists pioneered modern medicine with the invention of angioplasty and the catheter-delivered stent, which were first used to treat peripheral arterial disease. By using a catheter to open the blocked artery, the procedure allowed an 82-year-old woman, who refused amputation surgery, to keep her gangrene-ravaged left foot. To her surgeon’s disbelief, her pain ceased, she started walking, and three “irreversibly” gangrenous toes spontaneously sloughed. She left the hospital on her feet—both of them. Charles Dotter, M.D., the interventional radiologist that pioneered this technique, is known as the “Father of Interventional Radiology,” and was nominated for the Nobel Prize in medicine in 1978. Angioplasty and stenting revolutionized medicine and led the way for the more widely known applications of coronary artery angioplasty and stenting that revolutionized the practice of cardiology. Today many conditions that once required surgery can be treated nonsurgically by interventional radiologists. Through a small knick in the skin, they use tiny catheters and miniature instruments so small they can be run through a person’s network of arteries to treat at the site of illness internally, saving the patient from open invasive surgery.

    AMSER GUIDE TO APPLYING FOR INTERVENTIONAL RADIOLOGY RESIDENCY VERSION 1 – AUGUST 2016 DEVELOPED AND EDITED BY Kyle J. Cooper, M.D.; Minhaj S. Khaja, M.D., M.B.A.; Sravanthi Reddy, M.D., Kate Klein, M.D. WITH HELP AND INPUT FROM OTHER AMSER MEMBERS INTRODUCTION This document is intended to provide guidance for students considering applying to a residency in interventional radiology, known to many as IR/DR). It includes answers to the most common questions that advisors and program directors have been asked, as well as some “hard data” from the national websites. Some advice reflects personal opinion of the authors. WHY INTERVENTIONAL RADIOLOGY? Unfortunately, many medical students are not exposed to interventional radiology until their third or fourth year of medical school, if at all. This can make it difficult for students to decide if this is the specialty choice for them. The following is general information about the specialty and the sort of personalities that tend to enjoy it as a profession. Careers in Medicine® (CiM) Vascular and interventional radiologists use their expertise in interpreting X-rays, ultrasound, and cross-sectional imaging other medical modalities to guide small instruments such as catheters and wires through the blood vessels or other pathways to treat disease percutaneously. These procedures are typically much less invasive and much less costly than traditional surgery. These radiologists diagnose and treat diseases by various radiologic imaging modalities including fluoroscopy, digital radiography, computed tomography, sonography, and magnetic resonance imaging. Common interventional radiological procedures include: angioplasty; thrombolytic therapy for blood clots; chemoembolization--delivery of chemotherapy directly to the site of the tumor; infection and abscess drainage; uterine fibroid embolization; removal of a urinary tract or fallopian tube obstruction; needle biopsy; and radiofrequency ablation.
