Positron Emission Tomographic Imaging in Stroke

چکیده
T here is increased incidence of cognitive dysfunction after stroke. One in 10 develops vascular cognitive impairment after a single stroke and 1 in 3 after recurrent stroke. 1 Risk factors that predispose to atherosclerosis are also independently associated with an increased risk of dementia. In a review, we summarized the evidence supporting an increased risk of developing Alzheimer disease (AD) and vascular cognitive impairment in those with cardiovascular risks. 2 Although there is evidence of considerable overlap between AD and vascular cognitive impairment based on histopathologic survey, 3 the concomitant presence of AD and cerebrovascular pathology is not regarded as proof of a causal relationship between the 2.

PET Radiopharmaceuticals
PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

متن کاملPositron Emission Tomographic Imaging in Stroke: Cross-Sectional and Follow-Up Assessment of Amyloid in Ischemic Stroke.
BACKGROUND AND PURPOSE Cardiovascular risk factors significantly increase the risk of developing Alzheimer disease. A possible mechanism may be via ischemic infarction-driving amyloid deposition. We conducted a study to determine the presence of β-amyloid in infarct, peri-infarct, and hemispheric areas after stroke. We hypothesized that an infarct would trigger β-amyloid deposition, with deposi...
متن کاملIn vivo molecular imaging of thrombosis and thrombolysis using a fibrin-binding positron emission tomographic probe.
BACKGROUND Fibrin is a major component of arterial and venous thrombi and represents an ideal candidate for molecular imaging of thrombosis. Here, we describe imaging properties and target uptake of a new fibrin-specific positron emission tomographic probe for thrombus detection and therapy monitoring in 2 rat thrombosis models. METHODS AND RESULTS The fibrin-binding probe FBP7 was synthesize...
متن کاملThe effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملDetection of Alzheimer\\\\\\\'s Disease using Multitracer Positron Emission Tomography Imaging
Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...
