Cultivating Physician Character in Diagnostic Radiology Through Virtuous Caring and Collaborative Professionalism
Publication date: Available online 25 May 2018 Source:Academic Radiology Author(s): Keith D. Herr, Tarek N. Hanna, Nicole Restauri In the contemporary environment of patient- and value-centered care, it is no longer sufficient to limit the definition of an “excellent radiologist” to someone who is skilled at image interpretation. Since diagnostic radiologists are physicians, they are held to a certain character standard expected of a physician, whose primary objective is to serve the best interest of patients. An “excellent radiologist,” then, is better defined as one who is both skilled at interpr...

Building Imaging Institutes of Patient Care Outcomes
We describe the need for imaging institutes centered on disease entities (eg, lung cancer, multiple sclerosis) to not only optimize clinical care and patient outcomes, but also spur the development of a new educational focus, which will increase opportunities for medical trainees and other health professionals. These institutes will also serve as unique environments for testing and implementing new technologies and for generating new ideas for research and health-care delivery. We propose that the imaging institutes focus on how imaging practices—including new innovations—improve patient care outcomes within a ...

Addressing Potential Health Disparities in the Adoption of Advanced Breast Imaging Technologies
Publication date: May 2018 Source:Academic Radiology, Volume 25, Issue 5 Author(s): Randy C. Miles, Tracy Onega, Christoph I. Lee With the advent of new screening technologies, including digital breast tomosynthesis, screening ultrasound, and breast magnetic resonance imaging, there is growing concern that existing disparities among traditionally underserved populations will worsen. These newer screening modalities purport improved cancer detection over mammography alone but are not offered at all screening facilities and often require a larger co-pay or out-of-pocket expense. Thus, the potential for worsening disparities...

MRI-derived Regional Biventricular Function in Patients with Chronic Thromboembolic Pulmonary Hypertension Before and After Pulmonary Endarterectomy
Conclusion While biventricular resynchronization and recovery of global predominantly RV function was observed, regional circumferential function mainly improved in the lateral and inferior walls of both ventricles and regional radial function in the RV wall and septum 12 days after PEA, suggesting fibers primarily affected by myocardial stress in patients with CTEPH possibly need a relatively longer recovery time.

Uncited Research Articles in Popular United States General Radiology Journals
Conclusion Of articles published in popular general radiology journals, only a very small number of original research investigations remained uncited a decade after publication. Given that citations reflect the impact of radiology research, this observation suggests that journals are appropriately selecting meaningful work. Investigators seeking to avoid futile publication might consider their research initiatives in light of these characteristics. (Source: Academic Radiology)

The Yellow Scale Is Superior to the Gray Scale for Detecting Acute Ischemic Stroke on a Monitor Display in Computed Tomography
Conclusions The detection of acute ischemic stroke is improved by changing the display monitor from the gray scale to the yellow scale. From the perspective of color psychology, yellow is associated with higher arousal, cheerfulness, confidence, creativity, and excitement. Therefore, the yellow scale may be suitable for a medical imaging display. (Source: Academic Radiology)

Radiology Education in Medical School and Residency
Discussion This multidisciplinary national survey found a deficiency in imaging education among interns across specialties and substantiates calls for formalized and improved radiology education in undergraduate medical education. Additionally, PDs had difficulty distinguishing which skills were most important, suggesting an unclear understanding of imaging ability needs for interns in respective specialties. More specific needs assessments are warranted on a national level. (Source: Academic Radiology)
