Role of Diffusion MRI Imaging in Assessment of Ischemic Brain Lesions
Mohamed Mohamed Alaa Eldien Beniamin;
Abstract
erebral stroke is a worldwide concern, it's classified as the second most common cause of death mainly among elderly.
Diffusion-weighted magnetic resonance imaging (MRI) can demonstrate cerebral ischemia and ischemic brain injury in the first several hours after onset of symptoms, when FLAIR and T2-weighted MRI may appear normal. It is hypothesized that these techniques could distinguish regions destined for infarction from those that will not progress to infarction.
This study is aiming to evaluate the role of DWI in detecting ischemic cerebral strokes its site, size in the patients with neurological manifestations as early as possible to help them benefit from the medical interventional management.
In this study we examined 40 patients (32 male and 8 female) with age range (24 to 80 year) suspecting stroke lesions the diffusion weighted image sequence detect 36 case positively and 4 cases were pitfalls as described.(3 false negatice and one false positive)
We observe that the false negative results of DWI were in the occipital and brain stem lesions, Vertebrobasilar
