Emergency computed tomography (CT) is a diverse and growing area of advanced diagnostic imaging. Improved technology has led to increasingly rapid, specific, and sensitive examinations for indications for trauma and nontrauma emergencies. Emergency examinations constitute a large, complex, and changing use of CT. Although this article cannot address all indications for emergency CT or all emergency CT examinations, this overview of emergency CT discusses indications, the role and use of CT, and CT methods for emergency situations encountered by CT staff working in or serving emergency departments. © 2020 American Society of Radiologic Technologists.A guiding principle in regenerative cardiology is the idea that the heart is uniquely designed and that the challenges associated with engineering heart tissue can be resolved by mimicking the heart's structure and physiology. This article explores the fundamental concepts behind myocardial tissue regeneration via cell-based and protein-based therapies and surveys biomimetic approaches to cardiac perfusion, regeneration, and biocompatibility. In addition, it reviews biomimicry-based techniques for endovascular perfusion. © 2020 American Society of Radiologic Technologists.Nuclear medicine bone scans are a highly effective diagnostic tool, particularly when conducted in conjunction with other radiologic examinations. Typically, bone scans are used to diagnose a variety of skeletal conditions that cover the entire skeleton or occur in a specific location, including metastatic bone cancer, bone infections, or bone injuries. For each procedure, a small amount of a radiopharmaceutical agent is administered to the patient before scanning, and areas of the body that might be damaged or under repair will adsorb the agent. In general, bone scans are noninvasive with little to no adverse effects and are an important step in assessing the health of the skeletal system. © 2020 American Society of Radiologic Technologists.PURPOSE To evaluate medical imaging and radiation therapy professionals' perceptions of conducting research. METHODS Using a descriptive survey approach, a random sample of 10 000 American Society of Radiologic Technologists (ASRT) members was invited to share their experiences with conducting research, including challenges, reasons for not engaging in research, potential motivators, and support measures that would enhance their ability to conduct research in the medical imaging and radiation therapy profession. Three hundred ninety completed responses were analyzed for this study. RESULTS The majority (284, 72.8%) of the participants had no knowledge of or were slightly knowledgeable of the research process, and more than 75% of the participants did not feel prepared or felt they were only slightly prepared to conduct research. However, 257 (65.9%) of the participants believed it was very important to conduct research to advance the medical imaging and radiation therapy profession. Eighty-eight participants duct research, and providing research mentorships. CONCLUSION Increasing or improving the research being conducted among medical imaging technologists and radiation therapists and making such endeavors a priority can advance the profession and lead to better service to patients. © 2020 American Society of Radiologic Technologists.PURPOSE To determine the perceptions among radiographers of visible tattoos and nontraditional body piercings (piercings other than traditional pierced earlobes) in the clinical setting. METHODS An institutional review board-approved survey was delivered electronically to radiography clinical preceptors working at hospitals affiliated with a radiography program in the South Central part of the United States. Discussion board forum posts about the survey were created in the American Society of Radiologic Technologists Communities, targeting radiographers throughout the United States. Responses were collected for 4 weeks and compared quantitatively using linear regression, logistic regression, and chi-square analysis. Qualitative results were examined for themes, and proportions among themes were reported. RESULTS A total of 943 valid responses were received from radiographers working in the United States. Acceptance of body art was lower among individuals without tattoos compared with those who have tattoos (Parding the display of body art while working, even among those who have body art. selleckchem However, the subject of a tattoo might matter more than the location of a tattoo in terms of acceptability. These results have implications for the credibility and appropriateness of radiographers who display body art in the clinical setting because it might adversely affect the perceptions of co-workers and the perceptions of patient care provided during imaging services, and might affect hospital policy management. CONCLUSION Among radiographers working in the United States, a negative perception exists regarding visible body art such as tattoos and nontraditional piercings in the health care setting. Implications include negative perceptions of radiographers displaying body art while working. Future research might influence policy implementation as hospitals work to continually improve satisfaction scores and perceptions of care received. © 2020 American Society of Radiologic Technologists.PURPOSE To compare the MEDRAD Stellant and MEDRAD Stellant FLEX computed tomography contrast media injection systems in terms of radiologic technologists' ability to visually identify air in the syringes at various distances and under different lighting conditions, as well as the ease of cleaning contrast media spills on the injector faces. METHODS Ten experienced radiologic technologists performed 104 tests (52 per injector) in normal light and in ambient light conditions. The tests were randomized for the radiologic technologists' distance from the injector at 2 ft (61 cm), 8 ft (244 cm), and 16 ft (488 cm). In addition, the authors tested the cleaning efficiency of the Stellant injector face with raised buttons and the Stellant FLEX injector face with buttons on a flush surface by applying a mixture of contrast media and invisible ultraviolet ink. Radiologic technologists followed 2 cleaning protocols a quick clean (5 seconds) and a full clean (1 minute). Residual contrast mixture was measured. RESULTS The Stellant FLEX injector had an overall higher rate of correct air identification than did the Stellant injector, 97.
