Abstract
Introduction
Principles and applications of CT in stroke diagnosis Assessment of early ischemic changes and identification of hemorrhagic stroke Limitations and considerations in CT imaging [1].
Magnetic Resonance Imaging (MRI)
Basics of MRI and its advantages in stroke evaluation. Diffusion-weighted imaging (DWI) for early detection of ischemic stroke. T1-weighted and T2-weighted imaging for visualization of stroke lesions Magnetic resonance angiography (MRA) for assessment of vascular abnormalities [2].
Perfusion imaging
Principles and techniques of perfusion imaging Evaluation of cerebral blood flow, volume, and transit time in stroke Role of perfusion imaging in identifying viable tissue for potential intervention [3].
Advanced imaging techniques
Spectroscopy imaging for assessing metabolic changes in stroke Functional MRI (fMRI) for studying brain activity and plasticity post-stroke Positron emission tomography (PET) for evaluating brain metabolism and inflammation [4].
Artificial Intelligence and machine learning in stroke imaging
Potential applications of AI and ML algorithms in stroke diagnosis and prognosis Image analysis techniques for automated lesion detection and quantification Predictive modeling for personalized treatment planning and outcome prediction [5].
Conclusion
Summary of the current state of imaging techniques in stroke diagnosis and assessment. Prospects for further advancements and their potential impact on stroke management and patient outcomes. Imaging techniques have revolutionized the diagnosis and assessment of stroke, enabling rapid and accurate identification of stroke subtypes, evaluating the extent of brain damage, and guiding therapeutic decisions. With ongoing advancements in technology and the integration of artificial intelligence, imaging modalities are poised to play an increasingly vital role in stroke management. By further refining these techniques, researchers and clinicians have the opportunity to enhance stroke care, improve treatment outcomes, and ultimately reduce the burden of this devastating condition.
