  • Noninvasive retinal imaging may improve early detection of Alzheimer's disease
    on August 17, 2017 at 1:27 pm

    Alzheimer's disease (AD) represents the leading cause of dementia worldwide. Currently, challenges in making an early and definitive diagnosis of AD limit opportunities to intervene with disease-modifying therapies before substantial neurodegeneration occurs. Neurodegeneration in AD has been attributed to the accumulation of amyloid-beta proteins in the central nervous system, and amyloid-beta may be present up to 20 years prior to the onset of cognitive symptoms. Recently, noninvasive imaging techniques have been developed that can accurately detect and monitor amyloid-beta deposition in the retinas of rodent AD models. The use of similar techniques to assess amyloid-beta accumulation in human retinas may enable significant advances in early detection and treatment of AD. […]

  • Multicolor MRIs could aid disease detection
    on August 16, 2017 at 3:01 pm

Current MRI techniques rely on a single contrast agent injected into a patient's veins to vivify images. The new method uses two at once, which could allow doctors to map multiple characteristics of a patient's internal organs in a single MRI. The strategy could serve as a research tool and even aid disease diagnosis. […]

  • New OCT technique provides better 3-D imaging of the cellular structure of the eye
    on August 7, 2017 at 12:22 pm

    Optical Coherence Tomography (OCT) is a high-resolution live imaging technique that can be used for early detection of retinal diseases, such as age-related macular degeneration , diabetes-related conditions, glaucoma or vascular occlusions, for example. However, in order to obtain cellular resolution of the retina and hence even better results, it has so far been necessary to use expensive adaptive lenses to correct the image aberrations that occur. However, using a new technique, so-called Line Field OCT, researchers have now managed to simplify looking into the cellular processes in the eye to allow even more accurate diagnosis. […]

  • The power of radiomics to improve precision medicine
