Purpose New teaching formats are required to implement competency-based teaching in radiology teaching. Therefore, we have established and evaluated two practical competency-based radiological courses. Materials and Methods The courses were held in a multimedia room with 25 computers and a professional DICOM viewer. Students were taught basic image analysis and presented clinical cases with a DICOM viewer under supervision of an instructor using desktop monitoring software. Two courses (elective course and obligatory course) were evaluated by the students (n = 160 and n = 100) and instructors (n = 9) using an anonymized online survey...

During High Dose Rate Brachytherapy (HDR-BT) the spatial position of the radiation source inside catheters implanted into a female breast is determined via electromagnetic tracking (EMT). Dwell positions and dwell times of the radiation source are established, relative to the patient's anatomy, from an initial X-ray-CT-image. During the irradiation treatment, catheter displacements can occur due to patient movements. The current study develops an automatic analysis tool of EMT data sets recorded with a solenoid sensor to assure concordance of the source movement with the treatment plan...

Brain structure and function are tightly correlated across all animals. While these relations are ultimately manifestations of differently wired neurons, many changes in neural circuit architecture lead to larger-scale alterations visible already at the level of brain regions. Locating such differences has served as a beacon for identifying brain areas that are strongly associated with the ecological needs of a species-thus guiding the way towards more detailed investigations of how brains underlie species-specific behaviors...

REVIEW
Minhao Hu, David Wattchow, Dayan de Fontgalland
The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education...

PURPOSE: Multi-atlas-based method is extensively used in MR brain images segmentation because of its simplicity and robustness. This method provides excellent accuracy while time-consuming and limited in terms of obtaining information about new atlases. In this study, an automatic labeling of MR brain images through extensible learning and atlas forest is presented to address these limitations. METHODS: We propose an extensible learning model which allows the multi-atlas-based framework capable of managing the datasets with numerous atlases or dynamic atlas datasets and simultaneously ensure the accuracy of automatic labeling...

The capacity to read develops throughout intensive academic learning and training. Several studies have investigated the impact of reading on the brain, and particularly how the anatomy of the brain changes with reading acquisition. In the present study, we investigated the converse issue, namely whether and how reading acquisition is constrained by the anatomy of the brain. Using multimodal MRI, we found that (a) the pattern (continuous or interrupted sulcus) of the posterior part of the left lateral occipito-temporal sulcus (OTS) hosting the visual word form area (VWFA) predicts reading skills in adults; that (b) this effect is modulated by the age of reading acquisition; and that (c) the length of the OTS sulcal interruption is associated with reading skills...

OBJECTIVES: Many medical schools in Taiwan have adopted a dignified "silent mentor" initiation ceremony to strengthen student's medical humanity and increase their learning attitudes. This ceremony consists of introductions of the body donor's conduct and deeds, wreath-laying, and a tea party. However, few empirical studies have examined the influences of the ceremony and dissection on medical humanity. This study explored if the initiation ceremony and the course can help students care more about others, develop more positive attitudes toward death, improve learning effectiveness in the course, and decrease negative emotions the first time they see a cadaver...

Access to adequate anatomical specimens can be an important aspect in learning the anatomy of domestic animals. In this study, the authors utilized a structured light scanner and fused deposition modeling (FDM) printer to produce highly accurate animal skeletal models. First, various components of the bovine skeleton, including the femur, the fifth rib, and the sixth cervical (C6) vertebra were used to produce digital models. These were then used to produce 1:1 scale physical models with the FDM printer. The anatomical features of the digital models and three-dimensional (3D) printed models were then compared with those of the original skeletal specimens...

Continuing education (CE) is an essential element in the life-long learning of health care providers and educators. Despite the importance of the anatomical sciences in the training and practice of clinicians, no studies have examined the need/state of anatomy-related CE nationally. This study assessed the current landscape of CE in the anatomical sciences to contextualize preferences for CE, identify factors that influence the perceived need for CE, and examine the association between supply and demand. Surveys were distributed to educators in the anatomical sciences, practicing physical therapists (PTs), and anatomy training programs across the United States...

Intellectual disability is the unavoidable hallmark of Down syndrome (DS), with a heavy impact on public health. Reduced neurogenesis and impaired neuron maturation are considered major determinants of altered brain function in DS. Since the DS brain starts at a disadvantage, attempts to rescue neurogenesis and neuron maturation should take place as soon as possible. The brain-derived neurotrophic factor (BDNF) is a neurotrophin that plays a key role in brain development by specifically binding to tropomyosin-related kinase receptor B (TrkB)...

The purpose of this study was to evaluate the extracurricular cadaveric dissection program available to medical students at an institution with a modern (time-compressed, student-centered, and prosection-based) approach to medical anatomy education. Quantitative (Likert-style questions) and qualitative data (thematic analysis of open-ended commentary) were collated from a survey of three medical student cohorts who had completed preclerkship. Perceived benefits of dissection included the hands-on learning style and the development of anatomy expertise, while the main barrier that limited participation was the time-intensive nature of dissection...

REVIEW
Christopher L Reeves, Amber M Shane, Ryan Vazales
Much of the current literature suggests that total ankle replacement (TAR) is no longer an inferior or fringe treatment for advanced ankle arthritis compared with ankle fusion, but rather a viable option for recalcitrant arthritic ankle pathology in the correct patient population. In this article, current concepts associated with successful outcomes for TAR are discussed with an emphasis on ankle joint anatomy and biomechanics, preoperative planning and patient selection, understanding pathomechanics and soft tissue balancing, as well as the surgeon's learning curve...
