Intravoxel incoherent motion (IVIM) imaging is a concept and a method initially introduced and developed by Le Bihan et al. [1] [2] to quantitatively assess all the microscopic translational motions that could contribute to the signal acquired with diffusion MRI. In this model, biological tissue contains two distinct environments: molecular ...
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [1] This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3]
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke. Despite its lack of identifiable symptoms, a silent stroke still causes brain damage and places the patient at increased risk for a major stroke in the future. In a broad study in 1998, more than 11 million people ...
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
Among people with ischemic stroke, misdiagnosis occurs 2 to 26% of the time. [84] A "stroke chameleon" (SC) is stroke which is diagnosed as something else. [84] [85] People not having stroke may also be misdiagnosed with the condition. Giving thrombolytics (clot-busting) in such cases causes intracerebral bleeding 1 to 2% of the time, which is ...
[2] To determine the type and characteristics of a stroke, brain imaging is an essential part of the stroke patient evaluation process. The preferred imaging modality in this case is non-contrast computed tomography (CT) of the head. Depending on where they are or how big they are, anterior cerebral artery strokes may be overlooked on imaging ...
A microinfarct is a microscopic stroke generally ranging between 0.1 millimeter and 1 millimeter in size. [1] [2] Microinfarcts can be found in 25-50% of all elderly deceased persons. Microinfarcts may be the second most important cause of dementia, after Alzheimer's disease. [3] [4]
