Alzheimer’s disease, the most common neurodegenerative disorder globally, is often linked to atrophy of the hippocampus. However, a new study conducted by scientists at ShanghaiTech University has revealed that this decline may also be a result of the disease’s progression. Their findings were published in *Cell Reports Medicine*.
Magnetic resonance imaging (MRI) is currently the most advanced non-invasive technique in medicine for diagnosing and differentiating diseases, particularly those affecting the nervous system and brain. There are several types of MRI machines that can be used for specific situations. The capabilities and diagnostic potential of MRI depend on the strength of the magnetic field generated by the device, as well as the parameters that can be examined during the scanning session. These parameters include blood flow in nervous tissue, water diffusion between cells and regions, the overall structure of the brain and its segments, and, in the latest version of the device—multimodal MRI—the voxel size. Why is all of this important? Alongside the technology upgrade, advancements are being made in understanding how specific elements of human tissue, including the brain, develop and change. This is crucial for identifying diseases, as accurate identification can lead to effective treatment options.
