Sports injuries and illnesses during the Granada Winter Universiade 2015
OBJECTIVE To analyse the incidence of diseases and injuries suffered by athletes participating in the 27th Winter Sports Universiade held in Granada, Spain. METHODS The daily occurrence of injuries and diseases was registered at the point of first aid (Borreguiles, 2665 metres above sea level (masl)) and in the clinic of Pradollano (2017 masl), both in Sierra Nevada, as well as in medical ser...
متن کاملDual-Energy CT in Neuroimaging
Image contrast in CT is mostly dependent on elements with high atomic weight, such as calcium, iron, and iodine The concentrations of these elements can be calculated from dual-energy x-ray data based on their characteristic attenuation patterns Dual-energy CT may can be helpful in neuroimaging to: Differentiate between hemorrhage and iodinated contrast agents in brain parenchyma Improve CT ang...
متن کاملNonuniqueness in dual-energy CT.
PURPOSE The goal is to determine whether dual-energy computed tomography (CT) leads to a unique reconstruction using two basis materials. METHODS The beam-hardening equation is simplified to the single-voxel case. The simplified equation is rewritten to show that the solution can be considered to be linear operations in a vector space followed by a measurement model which is the sum of the ex...
متن کاملA novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
متن کاملSports injuries
Sports injuries fall into two general types. Acute traumatic injuries occur suddenly and usually involve a single application of force, for example, a hard tackle in football. They include fractures, breaks, bruises, sprains, strains and abrasions. Chronic or overuse injuries, by contrast, happen over a period of time. These injuries are usually the result of training that involves repetitive m...
