| Research Abstract |
Magnetic resonance imaging (MRI) is performed for diagnosis of acute ischemic stroke. The degree of signal intensity and the range of cerebral ischemia in diffusion-weighted magnetic resonance images (DWIs) and apparent diffusion coefficient (ADC) maps obtained by an MRI examination can provide important information regarding treatment options. However, the MR image information can change substantially depending on display conditions. Therefore, observing DWIs and ADC maps under improper image display conditions may result in detection errors of localized lesions and inaccurate delineation of the ischemic range. To assist radiologists and neurosurgeons to accurately interpret brain DWIs and ADC maps and make appropriate treatment decisions, we developed a computerized scheme for proper display of these images. Thus, we were able to construct a computerized scheme for accurate, prompt, and automated adjustment of display conditions in DWIs and ADC maps.
