| Popis: | Background Cerebrovascular disease represents a major source of global mortality and morbidity. Imaging examinations play a critical role in the management of stroke patients, from establishing the initial diagnosis to determining and guiding further treatment. Methods In this article, current CT and MRI methods employed in the management of stroke patients are reviewed, with an emphasis on ischemic stroke. Results The advantages and disadvantages of these techniques are discussed, a number of cases emphasizing key points are presented, and a comparison between modern CT and MRI techniques is outlined. Conclusion The major drawback of CT is the high radiation dose, while in MRI it is the more complicated and time-consuming aspect of the examination. Main Messages • Cerebrovascular disease represents a major source of global mortality and morbidity • Imaging examinations play a critical role in the management of stroke patients • The penumbra may be seen with both CT and MRI; however, this concept may be overly simplistic • The major drawback of CT is the high radiation dose, while MRI is a more complicated examination |
