Abstract
Stroke and cerebrovascular diseases are major causes of mortality, morbidity, and disability. Stroke is the third leading cause of death in Bangladesh. The World Health Organization ranks Bangladesh's mortality rate due to stroke as number 84 in the world. Rehabilitation services have not yet been integrated into the Bangladesh health system.Nuclear medicine imaging can play an important role in the diagnosis of stroke risk, the differential diagnosis of vascular and parenchymal cerebral abnormalities, and the understanding and management of post-stroke recovery.Nuclear Medicine, primarily via tomographic methods, has made substantial contributions to the considerate of the hemodynamic and metabolic significances of cerebrovascular diseases. Many of the pathophysiologic processes and consequences that follow stroke, including completed infarct core, adjacent penumbra, and diaschisis, have been investigated with Nuclear Medicine, and stroke outcome may be related to these phenomena. Several techniques, including vasodilatory stress imaging with regional cerebral blood flow (rCBF) single-photon emission computed tomography (SPECT), oxygen extraction methods with positron emission tomography (PET), and spectroscopic imaging with magnetic resonance spectroscopic imaging, offer ways to distinguish vascular from parenchymal dysfunction and to determine whether any observed abnormalities in cerebral blood flow are primary for secondary disease manifestations. Here we want to share our experiences regarding clinically diagnosed stroke with nuclear imaging at our institution.
