PURPOSE To determine the accuracy and reliability of three-dimensional (3D) T1- and proton density (PD)-weighted turbo spin-echo (TSE) sampling perfection with application-optimized contrasts using different flip-angle evolution (SPACE) compared with conventional 2D sequences in assessment of the shoulder-joint. MATERIALS AND METHODS Ninety-three subjects(More)
The VISual Concept Extraction challenge in RAdioLogy (VISCERAL) project has been developed as a cloud–based infrastructure for the evaluation of medical image data in large data sets. As part of this project, the ISBI 2014 (International Symposium for Biomedical Imaging) challenge was organized using the VISCERAL data set and shared cloud– framework. Two(More)
This is an overview paper describing the data and evaluation scheme of the VISCERAL Segmentation Challenge at ISBI 2015. The challenge was organized on a cloud-based virtual-machine environment, where each participant could develop and submit their algorithms. The dataset contains up to 20 anatomical structures annotated in a training and a test set(More)
We compared functional and structural changes in the hands, in particular the prevalence of carpal tunnel syndrome, in 56 paraplegic patients who had been wheelchair dependent for over 25 years with a group of able-bodied volunteers (with matching criteria for gender and age). The hands were assessed by clinical examination, electrophysiology, disabilities(More)
Variations in the shape and appearance of anatomical structures in medical images are often relevant radiological signs of disease. Automatic tools can help automate parts of this manual process. A cloud-based evaluation framework is presented in this paper including results of benchmarking current state-of-the-art medical imaging algorithms for anatomical(More)

PURPOSE To assess whether signal intensity (SI) different from that of cerebrospinal fluid (CSF) within the resection cavity during follow-up helps predict tumor progression in partially resected gliomas. MATERIALS AND METHODS This retrospective study had local institutional review board approval, with waiver of informed consent. Seventy-five patients(More)
