Hands-on Physics Education of Residents in Diagnostic Radiology
Conclusions An immersive, short-duration, clinically oriented physics rotation is well received by new or less experienced radiology trainees, correlates basic physics concepts with their relevance to clinical imaging, and more closely parallels expectations of the American Board of Radiology Core Examination.

White matter microstructural damage as predictor of cognitive decline in Parkinsons disease (P4.028)
Conclusions:Our results suggest that the presence of microstructural white matter alterations at baseline may be associated with the development or worsening of cognitive deficits in PD patients over two years. DTI offers new tools to identify PD patients at-risk for cognitive impairment.Study Supported by:Italian Ministry of Health (Grant #GR091577482) and Ministry of Education and Science Republic of Serbia (Grant #175090).Disclosure: Dr. Galantucci has nothing to disclose. Ms. Agosta has received personal compensation for activities with EXCEMED - Excellence in Medical Education as a speaker. Dr. Stojkovic has nothing t...

Three-dimensional printing in cardiology: Current applications and future challenges.
Abstract
Three-dimensional (3D) printing has attracted a huge interest in recent years. Broadly speaking, it refers to the technology which converts a predesigned virtual model to a touchable object. In clinical medicine, it usually converts a series of two-dimensional medical images acquired through computed tomography, magnetic resonance imaging or 3D echocardiography into a physical model. Medical 3D printing consists of three main steps: image acquisition, virtual reconstruction and 3D manufacturing. It is a promising tool for preoperative evaluation, medical device design, hemodynamic simulation and medical e...

“Let's Get Physical”: Advantages of a physical model over 3D computer models and textbooks in learning imaging anatomy
This study developed and evaluated the use of a physical model in demonstrating the complex spatial relationships of the equine foot. It was hypothesized that the newly developed physical model would be more effective for students to learn magnetic resonance imaging (MRI) anatomy of the foot than textbooks or computer‐based 3D models. Third year veterinary medicine students were randomly assigned to one of three teaching aid groups (physical model; textbooks; 3D computer model). The comparati ve efficacies of the three teaching aids were assessed through students' abilities to identify anatomical structures on MR images....

Efficient Segmentation of Brain Tumor Using FL-SNM with a Metaheuristic Approach to Optimization
AbstractNowadays, automatic tumor detection from brain images is extremely significant for many diagnostic as well as therapeutic purposes, due to the unpredictable shape and appearance of tumors. In medical image analysis, the automatic segmentation of tumors from brain using magnetic resonance imaging (MRI) data is the most critical issue. Existing research has some limitations, such as high processing time and lower accuracy, because of the time required for the training process. In this research, a new automatic segmentation process is introduced using machine learning and a swarm intelligence scheme. Here, a fuzzy log...

Expertise Modulates Students ’ Perception of Pain From a Self-Perspective: Quasi-Experimental Study
Conclusions: Virtual dental treatment activates pain-related brain regions in controls. By contrast, dental students suppress affective and motor-related aspects of pain. We speculate that dental students learn to control motoric aspects of pain perception during their education because it is a prerequisite for the professional manual treatment of patients. We discuss that a specific set of learning mechanisms might affect perceived self-efficacy of dental students, which in turn might reduce their affective component of pain perception.

The perspectives and the challenges of Paediatric Radiology: An interview with Dr Georgia Papaioannou, Head of the Paediatric Radiology Department at the 'Mitera' Children's Hospital in Athens, Greece.
Authors: Mammas IN, Spandidos DA
Abstract
Dr Georgia Papaioannou, MD, PhD, Head of the Paediatric Radiology Department at 'Mitera' Children's Hospital in Athens (Greece), is one of the most talented Paediatric Radiologists in Greece. She graduated from the Medical School of Athens of the National and Kapodistrian University of Athens in 1996 and she was trained in Radiology at the 2nd Department of Radiology of the Medical School of Athens and in Paediatric Radiology in Great Ormond Street Hospital for Children (GOSH) in London (UK). Her special interests focus on foetal magnetic resonance imaging (MRI) and special...

Are We Doing Enough to Reduce Ionizing Radiation Exposure in Children?: An Analysis of Current Approaches to Pediatric Appendicitis Imaging at a Major Urban Medical Center
Conclusions
Computed tomography scans were performed in 13.9% of patients with suspected AP. The overall AP rate was 28.4%. We plan to increase the use of magnetic resonance imaging and other modalities to reduce overall computed tomography usage.

How Are Dental Abscesses Treated?
Discussion
Dental caries are one of the most common infections. It is usually caused by Streptococcus viridans. Dental caries are also quite preventable with brushing the teeth at least twice a day with a fluoridated dentifrice, use of dental floss, and preventative dental appointments with application of fluoride varnish and sealants as appropriate. Additionally, fluoridation of the community water supply has significantly decreased dental caries and is a very effective public health measure. Fluoride binds within the dental matrix to strength it.
Dental abscesses are usually caused by poor oral hygiene but others are at...

Medical overuse of therapies and diagnostics in rheumatology
AbstractMedical overuse leads to a burden on healthcare costs and potentially is harmful to patients. We wanted to address medical overuse in musculoskeletal disease and rheumatology. We performed a systemic literature review from PubMed and Embase to study medical overuse. On the initial screen, 1499 studies were identified, 839 of them were related to medical overuse. Out of these, 52 were related to overuse in musculoskeletal diseases. Finally, 20 articles were chosen for this systemic review that reported overuse in rheumatology. The article identifies issues with overtesting, including the use of dual-energy X-ray abs...
