The diagnosis of enlarged lymph nodes is of the utmost importance especially in the treatment planning of cancer patients. US yields such morphological findings as node size, longitudinal/transverse diameter ratio, hilum visibility and cortical thickness, which however do not permit the differential diagnosis of benign from malignant forms. Some authors(More)
To face climate change, Switzerland has introduced the 2050 energy strategy by fixing greenhouse gas (GHG) emissions for the built environment. Designers will, as a result, have to use Life-Cycle Assessment (LCA) to increase operating performances while minimizing embodied impacts, but the integration of LCA at an early design stage adds a degree of(More)
Due to different temporal combinations of energy generation processes, the global warming potential (GWP) of energy supply evolves constantly. Despite this, the greenhouse gas (GHG) emissions related to the energy consumption in buildings are commonly assessed with yearly averaged carbon content of the energy supply. The knowledge of the hourly carbon(More)
We investigated the reliability of some US signs in the diagnosis of the carpal tunnel syndrome. We carried out a single-blind study with 13-MHz high resolution probes and electromyography on 132 patients with clinical evidence of the carpal tunnel syndrome; a control group of 20 asymptomatic patients was also submitted to US. Eighty-six of 107 patients(More)
To identify some dynamic or morphological patterns for the diagnosis of small bowel obstruction by hernia, adhesions or volvulus, we submitted to ultrasonography (US) 61 patients with clinical and radiographic syndromes of mechanical small bowel obstruction. The cause of obstruction was demonstrated in 58 patients-namely, with surgery in 56 patients and(More)
The typical US pattern of obstructive atelectasis consists in a triangular hypoechoic area with anechoic bands inside related to fluid-filled bronchial structures--the US fluid bronchogram sign. According to some authors, this US sign within a chest mass indicates pulmonary parenchyma disease. Furthermore, it suggests the diagnosis of lung collapse.(More)
