MRI biomarkers refer to specific characteristics observed in MRI images that can provide valuable information about underlying disease processes, treatment response, and prognosis. These biomarkers are used in various medical fields, such as neurology, oncology, and cardiology, to aid in diagnosis and monitoring of diseases. Some common MRI biomarkers include the presence of lesions or abnormalities in specific regions of the brain, changes in tissue density or composition, blood flow patterns, and the presence of specific molecules or proteins within tissues. These biomarkers can help clinicians and researchers better understand disease progression, tailor treatment plans, and evaluate the effectiveness of therapies. Overall, MRI biomarkers play a crucial role in advancing medical research and personalized medicine by providing non-invasive and detailed insights into the physiological and pathological changes within the body.
