Objectives: To identify and prioritize technical procedures for simulation-based training that should be part of the education of residents in radiology.

Methods: This European-wide needs assessment study used a modified Delphi technique to gather consensus from different key education stakeholders in the field. The first round was a brainstorming phase to identify all procedures that a newly specialized radiologist should potentially be able to do.

The Performance of Deep Learning Algorithms on Automatic Pulmonary Nodule Detection and Classification Tested on Different Datasets That Are Not Derived from LIDC-IDRI: A Systematic Review.

The aim of this study was to systematically review the performance of deep learning technology in detecting and classifying pulmonary nodules on computed tomography (CT) scans that were not from the Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI) database. Furthermore, we explored the difference in performance when the deep learning technology was applied to test datasets different from the training datasets. Only peer-reviewed, original research articles utilizing deep learning technology were included in this study, and only results from testing on datasets other than the LIDC-IDRI were included.

Simulation-Based Training of Ultrasound-Guided Procedures in Radiology - A Systematic Review.

Purpose:  To perform a systematic review of the effect of simulation-based training (SBT) of percutaneous abdominal and thoracic ultrasound-guided procedures and to assess the transfer of procedural competence to a clinical context.

Materials And Methods:  This systematic review was conducted in accordance with the PRISMA statement. Pubmed, Embase, Web of Science, and the Cochrane Library were searched for studies assessing procedural competence after SBT.

Four Virtual-Reality Simulators for Diagnostic Abdominal Ultrasound Training in Radiology.

Ultrasound exams need skilled examiners, and simulation-based training could provide standardized and safe skill training. This study aims to give an overview of different types of virtual-reality simulators for use in abdominal diagnostic ultrasound training in radiology. Fifteen specialized radiologists and radiological residents were presented with two similar cases on four different simulators for abdominal ultrasound training.

Simulator training improves ultrasound scanning performance on patients: a randomized controlled trial.

Background: Simulation-based mastery training may improve clinical performance. The aim of this study was to determine the effect of simulation-based mastery training on clinical performance in abdominal diagnostic ultrasound for radiology residents.

Method: This study was a multicenter randomized controlled trial registered at clinicaltrials.

Determining procedures for simulation-based training in radiology: a nationwide needs assessment.

Objectives: New training modalities such as simulation are widely accepted in radiology; however, development of effective simulation-based training programs is challenging. They are often unstructured and based on convenience or coincidence. The study objective was to perform a nationwide needs assessment to identify and prioritize technical procedures that should be included in a simulation-based curriculum.

Development of a reliable simulation-based test for diagnostic abdominal ultrasound with a pass/fail standard usable for mastery learning.

Background: This study aimed to develop a test with validity evidence for abdominal diagnostic ultrasound with a pass/fail-standard to facilitate mastery learning.

Method: The simulator had 150 real-life patient abdominal scans of which 15 cases with 44 findings were selected, representing level 1 from The European Federation of Societies for Ultrasound in Medicine and Biology. Four groups of experience levels were constructed: Novices (medical students), trainees (first-year radiology residents), intermediates (third- to fourth-year radiology residents) and advanced (physicians with ultrasound fellowship).

Clinical utility of F-FDG positron emission tomography/computed tomography scan vs. Tc-HMPAO white blood cell single-photon emission computed tomography in extra-cardiac work-up of infective endocarditis.

The extra-cardiac work-up in infective endocarditis (IE) comprises a search for primary and secondary infective foci. Whether FDG-PET/CT or WBC-SPECT/CT is superior in detection of clinically relevant extra-cardiac manifestations in IE is unexplored. The objectives of this study were to identify the numbers of positive findings detected by each imaging modality, to evaluate the clinical relevance of these findings and to define the reproducibility for extra-cardiac foci in patients with definite IE.

Brown Tumors Due to Primary Hyperparathyroidism in a Patient with Parathyroid Carcinoma Mimicking Skeletal Metastases on (18)F-FDG PET/CT.

Parathyroid carcinoma only represents <1% of all cases of primary hyperparathyroidism (PHPT). Even rare, chronic PHPT may lead to excessive osteoclast activity, and the increased resorption leads to destruction of cortical bone and formation of fibrous cysts with deposits of hemosiderin-so-called brown tumors. These benign, osteolytic lesions may demonstrate FDG-avidity on (18)F-FDG PET/CT, and as such are misinterpreted as skeletal metastases.

Angiosarcoma of the Scalp: Metastatic Pulmonary Cystic Lesions Initially Misinterpreted as Benign Findings on 18F-FDG PET/CT.

Angiosarcomas are rare and only represent about 2% of all soft tissue sarcomas. They arise from vascular or lymphatic endothelial cells and are most commonly located in the heart, liver, breast, and skin. Cutaneous angiosarcoma of the scalp is highly malignant and with dismal prognosis.

[Method for evaluating the competence of specialists--the validation of 360-degree-questionnaire].

Introduction: Assessment of physicians' performance focuses on the quality of their work. The aim of this study was to develop a valid, usable and acceptable multisource feedback assessment tool (MFAT) for hospital consultants.

Prevention of overuse injuries by a concurrent exercise program in subjects exposed to an increase in training load: a randomized controlled trial of 1020 army recruits.

Background: It is unknown whether an exercise program can prevent overuse injuries in the lower extremity. An often encountered and important risk factor for the development of lower extremity overuse injuries is an abrupt increase in activity level.

Hypothesis: A preventive training program based on a literature review of intrinsic risk factors, and performed concurrent with an increase in physical activity, can reduce the incidence of overuse knee injuries and medial tibial stress syndrome, as well as increase running distance.
