Visualization of Alzheimer's Disease on MRI

技術優勢
Wider clinical availability of MRI compared to other imaging techniques, including PET Utilizes better anatomical resolution capability of MRI compared to other imaging techniques, including PET Does not require cyclotron or similar equipment or entail special training for MRI personnel Relatively long shelf-life compared to radioactive probes (order many months) improves availability for administration at any facility with MRI equipment access Relatively long blood half-life compared to radioactive probes (hours to days) facilitates monitoring of AD related tissue changes with a single administration Lack of radioactivity allows repeated administration in patients and healthy research subjects Minimally invasive diagnostic method, in contrast to CSF collection by spinal tap
技術應用
Diagnosis of AD in the earliest stages of the disease using standard MRI equipment. Assessment of the efficacy of future experimental drugs in removing lesions or preventing their formation.
詳細技術說明
Researchers at UCLA have developed a targeted and non-radioactive compound that produces MRI image contrast enhancement of specific brain tissues containing A-beta plaques and neurofibrillary tangles. This compound can pass through the blood brain barrier and has demonstrated both differential affinity for these diseased tissues and effective MRI contrast resolution. This innovation is designed to use a non-invasive method and widely available equipment to help physicians diagnose AD patients and monitor their disease progression and/or response to treatment objectively and quantitatively.
*Abstract

State Of Development

The researchers have developed this compound. Experiments using a rodent model of triple transgenic human plaques associated with AD have demonstrated the efficacy of this compound in rendering these specific brain tissues readily visible on MRI. Manuscript on this work is being prepared for publication.


Background

An estimated 5.3 million Americans have AD, the most common form of dementia. For decades, diagnosis of AD has relied on the evaluation of cognitive impairment by neuropsychological tests. However, most medical experts now agree that AD actually begins long before patients exhibit clinical symptoms. Beta-amyloid (A-beta) plaques and neurofibrillary tangles, the pathological hallmarks of the disease, actually appear in the brain much earlier. Recent efforts to identify these brain lesions early, including by positron emission tomography (PET) imaging or by cerebral spinal fluid (CSF) testing, have met with some success. Additional methods for early AD diagnosis may yield new progress in the development of therapeutics that can slow or stop the disease.
