Radiation-associated kidney injury.
The kidneys are the dose-limiting organs for radiotherapy to upper abdominal cancers and during total body irradiation. The incidence of radiotherapy-associated kidney injury is likely underreported owing to its long latency and because the toxicity is often attributed to more common causes of kidney injury. The pathophysiology of radiation injury is poorly understood. Its presentation can be a...
متن کاملCT of brainstem injury.
Cranial computed tomography (CT) scans of 1,600 head trauma patients, 67 of which demonstrated evidence of brainstem injury, were reviewed. CT diagnosis of brainstem injury was based on direct and indirect evidence. Direct signs, which include focal hemorrhage, significant intraparenchymal contrast enhancement, hemorrhagic contusion, and edema of the brainstem, appear as areas of high density, ...
متن کاملBrainstem lesions after head injury.
There is little knowledge on the morphology of the brain stem in survivors of head injury, as CT fails to shown brain stem lesions, and neuropathological data is only available from autopsies. As magnetic resonance imaging (MRI) sheds new light on morphological lesions of the brain, the authors investigated 100 patients with a severe head injury. MRI was performed in a prospective study within ...
متن کاملSpace radiation-associated lung injury in a murine model.
Despite considerable progress in identifying health risks to crewmembers related to exposure to galactic/cosmic rays and solar particle events (SPE) during space travel, its long-term effects on the pulmonary system are unknown. We used a murine risk projection model to investigate the impact of exposure to space-relevant radiation (SR) on the lung. C3H mice were exposed to (137)Cs gamma rays, ...
متن کاملRadiation Injury
magnetic shutter, flash techniques, rotating shutters, the stroboscope and several high-speed techniques such as the Kerr Cell. Crawford and Jones explain how the measurement and calibration of the stimulus is accomplished by comparing it with a standard source using a thermopile, bolometer, photocell or other light sensitive device. They explore the knowledge of photometric and radiometric rel...
