BACKGROUND: In IGRT of deformable head-and-neck anatomy, patient setup corrections are derived by rigid registration methods. In practice, experienced radiation therapists often correct the resulting vectors, thus indicating a different prioritization of alignment of local structures. Purpose of this study is to transfer the knowledge experts apply when correcting the automatically generated result (pre-match) to automated registration. METHODS: Datasets of 25 head-and-neck-cancer patients with daily CBCTs and corresponding approved setup correction vectors were analyzed...

Background and study aim Magnifying narrow-band imaging (M-NBI) is useful for the accurate diagnosis of early gastric cancer (EGC). However, acquiring skill at M-NBI diagnosis takes substantial effort. An Internet-based e-learning system to teach endoscopic diagnosis of EGC using M-NBI has been developed. This study evaluated its effectiveness. Participants and methods This study was designed as a multicenter randomized controlled trial. We recruited endoscopists as participants from all over Japan. After completing Test 1, which consisted of M-NBI images of 40 gastric lesions, participants were randomly assigned to the e-learning or non-e-learning groups...

Graduating physicians in all subspecialties have an increased need for competency in radiology, particularly since the use of diagnostic imaging continues to grow. To integrate the teaching of radiology with anatomy during the first year of medical school at Howard University, a novel approach was developed to overcome the limitations of resources including funding, faculty, and curricular time. The resulting program relies on self-study and peer-to-peer interactions to develop proficiency at manipulating free versions of medical image viewer software (using the DICOM standard), identifying normal anatomy in medical images, and applying critical thinking skills to understand common clinical conditions...

This project evaluated a low-cost sponge phantom setup for its capability to teach and study A- and B-line reverberation artifacts known from lung ultrasound and to numerically simulate sound wave interaction with the phantom using a finite-difference time-domain (FDTD) model. Both A- and B-line artifacts were reproducible on B-mode ultrasound imaging as well as in the FDTD-based simulation. The phantom was found to be an easy-to-set up and economical tool for understanding, teaching, and researching A- and B-line artifacts occurring in lung ultrasound...

Scholars have identified two distinct ways of thinking. This "Dual Process Theory" distinguishes a fast, nonanalytical way of thinking, called "System 1," and a slow, analytical way of thinking, referred to as "System 2." In radiology, we use both methods when interpreting and reporting images, and both should ideally be emphasized when educating our trainees. This review provides practical tips for improving radiology education, by enhancing System 1 and System 2 thinking among our trainees.

External fixation of the elbow requires identification of the elbow rotation axis, but the accuracy of traditional landmarks (capitellum and trochlea) on fluoroscopy is limited. The relative distance (RD) of the humerus may be helpful as additional landmark. The first aim of this study was to determine the optimal RD that corresponds to an on-axis lateral image of the elbow. The second aim was to assess whether the use of the optimal RD improves the surgical accuracy to identify the elbow rotation axis on fluoroscopy...

OBJECTIVE: Interpretation of abdominal radiographs of children benefits from a firm knowledge of the congenital anomalies and pathologies unique to this patient population, leveraged by a systematic approach. Interpretive errors place the patients and their families at risk for a delay in diagnosis, unnecessary additional imaging, a potential increase in the radiation burden, and possible psychologic trauma. CONCLUSION: In this article, we describe the common and uncommon potential pitfalls in pediatric abdominal radiography, using several of our own interpretive errors as a framework while providing teaching points to help avoid these mistakes...

INTRODUCTION: Civilian penetrating gunshot injuries to the neurocranium are no longer uncommon in Nigeria. Such injuries are however poorly reported. They are associated with poor outcome and, at close range, are frequently fatal, especially when inflicted by high-velocity weapons. Prompt transfer to neurosurgical service and urgent intervention may improve outcome in those that are not mortally wounded. MATERIALS AND METHODS: Fifty-two patients with civilian penetrating gunshot wounds seen over a 10-year period (2004-2014) at the University of Nigeria Teaching Hospital and Memfys Hospital for Neurosurgery Enugu were reviewed retrospectively, and their data were analyzed to evaluate factors that impacted on outcome...

In the native language, abstract and concrete nouns are represented in distinct areas of the cerebral cortex. Currently, it is unknown whether this is also the case for abstract and concrete nouns of a foreign language. Here, we taught adult native speakers of German 45 abstract and 45 concrete nouns of a foreign language. After learning the nouns for 5 days, participants performed a vocabulary translation task during functional magnetic resonance imaging. Translating abstract nouns in contrast to concrete nouns elicited responses in regions that are also responsive to abstract nouns in the native language: the left inferior frontal gyrus and the left middle and superior temporal gyri...

In teaching and learning human anatomy, anatomical autopsy and prosected specimens have always been indispensable. However, alternative methods must often be used to demonstrate particularly delicate structures. Corrosion casting of porcine organs with Biodur E20(®) Plus is valuable for teaching and learning both gross anatomy and, uniquely, the micromorphology of cardiovascular, respiratory, digestive, and urogenital systems. Assessments of casts with a stereomicroscope and/or scanning electron microscope as well as highlighting cast structures using color coding help students to better understand how the structures that they have observed as two-dimensional images actually exist in three dimensions, and students found using the casts to be highly effective in their learning...
