Book Description
This Report is focused on the use of fluoroscopic systems as a tool for guiding diagnostic and therapeutic procedures because higher radiation doses (compared to conventional radiography and fluoroscopy) are received regularly from some types of FGI procedures and occasionally from many other types of FGI procedures. Other medical applications of fluoroscopy (e.g., examination of the gastrointestinal system, guiding open surgical procedures) are outside the scope of this Report. Computed- tomography-guided interventional (CTGI) procedures are not discussed in detail due to continuing changes in the technology driven by the evolution of multi-slice computed tomography (CT) detectors. However, the principles presented in this Report are generally applicable to these domains. Most of the recommendations contained in this Report should be applied in all settings where fluoroscopic guidance is used. Within the context of radiation dose management, the goal of this Report is to supply information that helps optimize patient outcomes without compromising worker safety. However, radiation is not the only risk to which patients and workers are exposed. In many cases, radiation is a minor component of overall risk. In these situations, too great a focus on radiation safety (e.g., the use of unnecessarily thick lead aprons) may reduce the overall safety of patients or workers. Some beneficial, clinically-justified FGI procedures, even when optimized for radiation protection, deliver substantial doses of radiation to patients. This puts the patient at risk for radiogenic stochastic effects and occasionally induces radiogenic deterministic effects. However, a complete risk analysis usually identifies many other procedural hazards and will often conclude that radiation is one of the lesser hazards from FGI procedures. While the decision to conduct an FGI procedure assumes that the use of ionizing radiation is warranted by the disease state for which

Book Description
Recent studies have shown that workers who perform fluoroscopically guided interventional (FGI) procedures have an increased risk for developing cancer, cataracts, skin lesions and orthopedic illnesses. The purpose of this pilot study was to evaluate the potential effects of utilizing a personnel radiation dose tracking system, with "graphical feedback" information on FGI worker behavior. Methods: Eight months of FGI worker radiation dose data (mrem/procedure) prior to and after implementation of the GDD tool were used in this study. A 44 item questionnaire was developed and administered electronically to physician and non-physician fluoroscopic equipment operators. Descriptive statistics and repeated measures ANOVA was utilized. Results: After data cleaning, 39 operators (67% physicians and 33% non-physicians) were used for the analyses. Analysis was performed utilizing the operator responses to the survey statement, "The GDD email is an important reminder to use appropriate safety practices". Significant decreases in mean operator doses were indicated. In addition, the results indicate that those who are likely to have no barriers to using personal protective equipment have a lower dose compared to operators who indicated they have barriers. Conclusion: Results of this pilot study have shown use of the GDD tool may be associated with a decrease in operator dose. Implications for instituting this approach as organizational policy include: 1) it meets the Centers for Medicare and Medicaid requirements for educating workers as to their dose over various time frames as well as their cumulative exposure through work and 2) meets state rules that require registrants to maintain worker exposures as low as reasonably achievable. In addition, it assists management personnel in identifying individuals that have consistently higher doses than expected. If poor practice is determined (e.g., using higher machine settings, inappropriate protocol use or not using appropriate PPE) and continues after additional training or consultation is provided, corrective action can be addressed as part of the individuals performance review. Poor safety practices not only put the operator at higher risk for health issues but also nearby support staff.

Book Description
This publication reports the results of a recent IAEA coordinated research project on patient dose optimization in fluoroscopically guided interventional procedures. The optimization of radiological protection of patients undergoing medical exposure has become an important issue, since many surgical procedures have increasingly been replaced by interventional ones, which can cause higher radiation exposure. The summary presents detailed information on the assessment of high skin doses, analyses the factors causing radiation skin injury and makes recommendations on how to avoid or reduce the li.

Book Description
Whenever a diagnostic or interventional X-ray examination of a pregnant patient is considered to be necessary, conceptus dose estimation is an essential step in assessing the radiogenic risks to the unborn child. Accurate estimation of embryo/fetus radiation dose is also needed after accidental exposure of a pregnant patient from an X-ray procedure. The exposure of pregnant patients to medical X-rays is often a complex case and involves emotionally sensitive issues for both prospective parents and physicians. Conceptus dose assessment is not always easy. Medical physicists should be able to assess conceptus doses and risks from diagnostic and interventional procedures and also to place the risk in a perspective from which an informed decision can be made. Pregnant medical professionals working with radiation have many misconceptions about the risks of ionizing radiation on the unborn child. Medical radiation workers of childbearing age should be aware that careful planning and dose optimization of examinations can address their concerns and permit, in the vast majority of cases, safe performance of procedures. Pediatric patients requiring diagnostic and interventional procedures are exposed to diagnostic and interventional X-rays. Pediatric patients are more sensitive to radiation than adults and, for this reason, accurate assessment of doses and risks is needed in these cases. Medical physicists should be able to assess paediatric doses and risks from diagnostic and interventional procedures. Several techniques and tools have been developed for dose optimization of radiographic, fluoroscopic, computed tomography and fluoroscopically-guided interventional pediatric procedures. The scan parameters should be adjusted for patient size and body region. Part of Series in Physics and Engineering in Medicine and Biology.

Book Description
Computed tomography (CT) is a powerful technique providing precise and confident diagnoses. The burgeoning use of CT has resulted in an exponential increase in collective radiation dose to the population. Despite investigations supporting the use of lower radiation doses, surveys highlight the lack of proper understanding of CT parameters that affect radiation dose. Dynamic advances in CT technology also make it important to explain the latest dose-saving strategies in an easy-to-comprehend manner. This book aims to review all aspects of the radiation dose from CT and to provide simple rules and tricks for radiologists and radiographers that will assist in the appropriate use of CT technique. The second edition includes a number of new chapters on the most up-to-date strategies and technologies for radiation dose reduction while updating the outstanding contents of the first edition. Vendor perspectives are included, and an online image gallery will also be available to readers.
