Purpose: To investigate the role of low-dose chest computed tomography (CT) imaging in the triage of patients suspected of coronavirus disease 2019 (COVID-19) in an emergency setting. Materials and Methods: Data from 610 patients admitted to our emergency unit from March 20, 2020, until April 11, 2020, with suspicion of COVID-19 were collected. Diagnostic values of low-dose chest CT for COVID-19 were calculated using consecutive ...

The activation cross sections of deuteron induced reactions on natural ruthenium have been measured up to 50MeV for production of radioisotopes of rhodium (105Rh, 102mRh,102gRh,101mRh,101gRh, 100gRh, 99mRh, 99gRh), ruthenium (105Ru,103Ru (cum), 102Ru (cum), 97Ru (cum), 95Ru (cum)) and of technetium (99mTc, 96gTc (m+), 95mTc (cum), 95gTc (cum), 94gTc,93gTc (m+)). The results are compared with the predictions of the most common theoretical nuclear ...

Accurate medical image segmentation is essential for diagnosis and treatment planning of diseases. Convolutional Neural Networks (CNNs) have achieved state-of-the-art performance for automatic medical image segmentation. However, they are still challenged by complicated conditions where the segmentation target has large variations of position, shape and scale, and existing CNNs have a poor explainability that limits their application to clinical ...

In order to limit and slow the development of diseases, they have to be diagnosed early as possible to treat patients in a better and more rapid manner. In this paper, we focus on a noninvasive and quick method based on diffuse fields in elastography to detect diseases that affect the stiffness of organs. To validate our method, a phantom experiment numerically pre-validated is designed. It consists of seven vibrators that generate white noises ...

A 27-year-old man was called to receive a kidney transplant. The preoperative CT of the chest showed multiple osteolytic lesions, as well as a hypodense structure posterior in the right thyroid lobe. Blood analysis showed elevated parathyroid hormone, phosphorus, and alkaline phosphatase levels, with normal calcium and 25-OH-vitamin D. F-FDG PET/CT demonstrated generalized elevated FDG uptake in the bone (due to hyperparathyroidism), as well as ...

Knee osteoarthritis (OA) is one of the highest disability factors in the world. This musculoskeletal disorder is assessed from clinical symptoms, and typically confirmed via radiographic assessment. This visual assessment done by a radiologist requires experience, and suffers from moderate to high inter-observer variability. The recent literature has shown that deep learning methods can reliably perform the OA severity assessment according to ...

Image-guided adaptive brachytherapy (IGABT) has been shown to improve local/regional control and survival for cervix cancer patients while reducing morbidity. However, the technique is complex involving several conceptual, methodological, and technical innovations compared to conventional brachytherapy. The delivery of high-quality IGABT which will translate into improved outcomes is therefore critically dependent on effective education and ...

BACKGROUND: Alveolar Soft Part Sarcoma (ASPS) is a rare, slow-growing, but highly vascular soft tissue sarcoma, characterised by a high rate of metastases at presentation. Although imaging features of the primary are well described, less detail is available on the imaging pattern of metastatic ASPS. The EORTC 90101 (CREATE) study assessed the efficacy of Crizotinib in patients with metastatic ASPS and presents a unique opportunity to describe ...
