Brain metabolic abnormalities associated with developmental venous anomalies.
BACKGROUND AND PURPOSE Developmental venous anomalies are the most common intracranial vascular malformation and are typically regarded as inconsequential, especially when small. While there are data regarding the prevalence of MR imaging findings associated with developmental venous anomalies, FDG-PET findings have not been well-characterized. MATERIALS AND METHODS Clinical information syste...
متن کاملERG ) - Oscillatory Potentials - Pattern Electroretinogram
Electrodiagnostic procedures have contributed to the certainty of diagnosis of a variety of neurological and neuromuscular diseases in animals. Widespread use of electrodiagnosis is limited by equipment costs and training of personnel. However, many of these procedures are used routinely in case work-ups in veterinary colleges or specialty practices. The purpose of this chapter is to present a ...
متن کاملElectroretinogram (ERG) Measurements in Larval Zebrafish.
INTRODUCTIONThe electroretinogram (ERG) is an electrophysiological tool used to measure electrical activity originating in the outer retina in response to a light stimulus. Defects occurring at various levels of the retina can easily be detected by ERG measurements. Furthermore, the shape of the ERG response points toward the likely retinal cell type responsible for the deficit. Thus, this meth...
متن کاملImage Findings in Brain Developmental Venous Anomalies
OBJECTIVE Developmental venous anomalies (DVAs) are benign anatomic variations; therefore, they are usually discovered incidentally. The aim of this article was to describe radiological findings of DVAs. METHODS A retrospective search for DVAs of the brain was performed in 1899 patients who had undergone magnetic resonance imaging (MRI) with contrast enhancement between January 1, 2005 and Ap...
متن کاملBrain parenchymal signal abnormalities associated with developmental venous anomalies in children and young adults.
BACKGROUND AND PURPOSE Abnormal signal in the drainage territory of developmental venous anomalies has been well described in adults but has been incompletely investigated in children. This study was performed to evaluate the prevalence of brain parenchymal abnormalities subjacent to developmental venous anomalies in children and young adults, correlating with subject age and developmental veno...
