Diffusion MR imaging of hypoglycemic encephalopathy.
BACKGROUND AND PURPOSE MR imaging features of HE have not been fully established. The purpose of this study was to determine the topographic distribution and DWI findings of HE. MATERIALS AND METHODS We retrospectively evaluated HE MR imaging (n = 11). The topographic distribution of the lesions was evaluated on routine MR imaging, and DWI SI and ADC values were assessed. The ADC value of inv...
متن کاملValue of diffusion-weighted imaging in hypoglycemic encephalopathy
H is the most common metabolic disorder that may cause neonatal encephalopathy and result in permanent brain injury.1 Prompt diagnosis is important as urgent treatment may change the progression of the disease and the future prognosis. Conventional MRI is useful to demonstrate the signal changes that are prominent on the occipital lobes; however, MRI may not show the pathology in the very early...
متن کاملDiffusion-weighted MR imaging findings of acute necrotizing encephalopathy.
Multiple, symmetrical brain lesions affecting the bilateral thalami and cerebral white matter, which often show a concentric structure on CT and MR images, characterize acute necrotizing encephalopathy (ANE) of childhood. We describe the imaging findings of a 2-year-old child with ANE obtained with diffusion-weighted MR imaging. We discuss the significance of these findings, as well as the path...
متن کاملMR imaging, MR spectroscopy, and diffusion tensor imaging of sequential studies in neonates with encephalopathy.
BACKGROUND Although the imaging, spectroscopic, and diffusion characteristics of brains of infants with neonatal encephalopathy have been described, the time course during which these changes evolve is not clear. The results of sequential MR imaging studies--including anatomic MR imaging, proton MR spectroscopy, and diffusion tensor imaging (DTI)--of 10 patients enrolled prospectively in a stud...
متن کاملDiffusion-weighted MR imaging in hypertensive encephalopathy: clues to pathogenesis.
PURPOSE Hypertensive encephalopathy, a complex of cerebral disorders, including headache, seizures, visual disturbances, and other neurologic manifestations, is associated with a variety of conditions in which blood pressure rises acutely. It has been ascribed to either exuberant vasospasm with ischemia/infarction or breakthrough of autoregulation with interstitial edema. Diffusion-weighted MR ...
