Like all medical procedures, medical imaging that uses ionizing radiation presents both benefits and risks. Medical imaging has led to improvements in the diagnosis and treatment of numerous medical conditions. At the same time, exposure to ionizing radiation may elevate patients' lifetime risk of developing cancer. Overexposure to ionizing radiation can also cause injuries in the short-term such as skin burns and hair loss. In an effort to reduce these risks, FDA's Center for Devices and Radiological Health (CDRH) recently announced the Initiative to Reduce Unnecessary Radiation Exposure from Medical Imaging (see http://www.fda.gov/Radiation-EmittingProducts/RadiationSafety/RadiationDoseReduction/UCM199904 for more information).
FDA is currently exploring steps that manufacturers of CT and fluoroscopic devices could take to reduce unnecessary radiation exposure through improved product design, enhanced labeling, or improved instructions and training for equipment use and quality assurance at medical imaging facilities.
II. Public Meeting
The objective of this public meeting is to receive public input on steps manufacturers of CT and fluoroscopic devices should take to help reduce unnecessary patient exposure to ionizing radiation from these medical imaging modalities.
The meeting will be held over the course of 2 days. Each day will be divided into two sessions. Day 1 will focus on equipment features that manufacturers should incorporate into CT scanners (morning session) and fluoroscopes (afternoon session). Day 2 will focus on steps manufacturers should take to improve training of individuals who use these devices (morning session) and steps to improve quality assurance at medical imaging facilities with respect to these two modalities (afternoon session).
During each session, members of the public may present oral comments related to the topic of that session. Specific questions for comment are listed in section III of this document, Questions for Comment. Individuals who are interested in giving an oral presentation during any of the sessions must indicate this interest at the time of registration and must also identify the session(s) at which they would like to present (see Registration). In order to keep each session focused on the topic at hand, each oral presentation should address only the topic specified for that session. Commentators are free to submit written comments on any topic(s) to the open docket (see Comments). FDA will schedule speakers for each session as time permits.
To close each of the four sessions, FDA will hold a roundtable discussion between FDA staff and selected participants representing a range of constituencies (for more information about participating in the roundtable discussion, see Registration). The participants in each roundtable discussion will remark on the presentations given during the session, engage in a dialogue with each other and FDA staff, and provide closing thoughts on the session. Roundtable participants will not be asked to develop consensus opinions during the discussion, but rather to provide their individual perspectives. Others in attendance at the meeting will have an opportunity to listen to each roundtable discussion.
In advance of the meeting, additional information, including a meeting agenda with a speakers' schedule for each session, will be made available on the Internet. This information will be placed on file in the public docket (docket number found in brackets in the heading of this document), which is available at http://www.regulations.gov. This information will also be available at http://www.fda.gov/MedicalDevices/NewsEvents/WorkshopsConferences/default.htm (select the appropriate meeting from the list).
III. Questions for Comment

Note: The questions in the following paragraphs are relevant to both CT and fluoroscopic devices. Please clearly indicate in your response which modality you are discussing. Additionally, while the questions are worded broadly, please feel free to include elements in your response that are specific to particular types of procedures (e.g., multi-phase contrast-enhanced CT examinations, perfusion studies, etc.) or devices (e.g., multidetector CT devices that allow very thin slices, etc.).
1. What hardware and software features should manufacturers build into CT and fluoroscopic devices in order to reduce unnecessary exposure to ionizing radiation during each imaging exam, and in order to reduce what may be inappropriate prescription of imaging exams? Should manufacturers incorporate special provisions for pediatric and female patients?
2. Should manufacturers incorporate access controls and audit capabilities into CT and fluoroscopic equipment in order to identify the user(s) of the device during any particular exam, and to identify those responsible for creating and changing imaging protocols and exposure settings? If so, why, and what access controls and audit capabilities should be incorporated? If not, why not?
3. Should manufacturers incorporate warnings, alerts, lockouts, or overrides into CT and fluoroscopic equipment that would inform users and require confirmation or possibly procedure modification during an imaging session in which the patient could be exposed to high levels of radiation? If so, why, and what warnings, alerts, lockouts, or overrides should be incorporated? If not, why not?
4. Should manufacturers set default imaging protocols for CT and fluoroscopic procedures so that they incorporate the ALARA concept (maintaining dose As Low As Reasonably Achievable) and utilize or provide for incorporation of diagnostic reference levels into CT and fluoroscopic devices? If so, why and how? If not, why not?
5. Should manufacturers incorporate exam referral criteria into CT and fluoroscopy equipment to allow users to check the appropriateness of an imaging exam before it is initiated or flag an exam after it is done? If so, why and how? If not, why not?
6. Should manufacturers incorporate into CT and fluoroscopic equipment features to ensure that exposure settings, imaging protocols, and metrics of body dose and peak skin dose are displayed to the operator(s) of the equipment and recorded for physician review? If so, why and how? If not, why not?
7. Should manufacturers incorporate features into CT and fluoroscopic equipment to facilitate transmission of technique parameters, imaging protocols, and dose metrics to a patient's imaging record, an electronic health record, or other database? If so, why and how? If not, why not?
8. Should manufacturers take steps to improve the labeling of CT and fluoroscopic devices, such as including more information about radiation exposure, including more informationabout the clinical applications of the device that have been shown to be safe and effective, improving instructions for use for each distinct clinical application, and including a comprehensive quality control manual? If so, why and how? If not, why not?
9. Should manufacturers submit more data to FDA as part of their premarket submissions for approval or clearance of CT and fluoroscopic devices, related to the safety and effectiveness of these devices (e.g., data demonstrating the safety and effectiveness of the device specific to each distinct clinical indication, or clinical data demonstrating the benefit of relatively high-dose procedures, for example, those with peak skin doses exceeding 1 Gy)? If so, why, and what data should be submitted? If not, why not?
10. Should manufacturers submit technical data to FDA as part of their premarket submissions for approval or clearance of CT and fluoroscopic devices, demonstrating dose reduction and image quality claims? If so, why, and what data should be submitted? If not, why not?
11. In addition to the already-required indications for use statement, should manufacturers of CT and fluoroscopic devices submit to FDA as part of their premarket submissions a list of common clinical applications for which the device could be used (such as those requiring special software supported by the device) and the appropriate demographics of the likely patient populations for those exams? If so, why, and what level of information should be submitted? If not, why not?
12. What changes should manufacturers make to CT and fluoroscopic devices currently on the market in order to reduce unnecessary patient exposure to ionizing radiation?
B. User Training
1. Should manufacturers provide training to medical imaging equipment users to ensure adequate understanding of equipment capabilities, operating principles for the technology, general information about optimizing patient dose and image quality, and specific dose-reduction equipment features? If so, why, and what training should be provided? If not, why not?
2. If manufacturers provide such training, which personnel should receive it to ensure proper use of medical imaging equipment and dose reduction features? In your response, please consider radiologic technologists or technologists in other specialties as well as physicians in all medical specialties who operate fluoroscopic equipment.
3. If manufacturers provide such training, how, when, and how often should it be delivered so that it is easily and effectively implemented at imaging facilities? For example, for software upgrades that affect dose, should training be performed at each site as well as training at the time of equipment installation?
C. Quality Assurance Measures
1. Should manufacturers provide quality assurance (QA) instructions and standard operating procedures to medical imaging facilities and users of CT and fluoroscopic devices? If so, why, and what instructions should be provided? If not, why not?
2. Should manufacturers provide training on quality assurance practices? If so, why, what type of training should be provided, and to which personnel? If not, why not?
1. What tools and metrics should FDA, in collaboration with others in the Federal Government and the healthcare professional community, use to evaluate the impact of efforts to reduce unnecessary radiation exposure from medical imaging?
