WebApr 12, 2024 · MRI is the most sensitive imaging method when it comes to examining the structure of the brain and spinal cord. It works by exciting the tissue hydrogen protons, which in turn emit electromagnetic signals back to the MRI machine. The MRI machine detects their intensity and translates it into a gray-scale MRI image. WebIn practice, T1 weighted images are used mostly to evaluate normal anatomy. Remember that only a few structures have a high signal intensity (= white) on a T1 weighted image: fat, blood, gadolinium (= contrast), melanin, protein (e.g. high-protein cysts). A high signal can also be seen in specific MRI artifacts and accumulation diseases (not ... WebTissues with short T1's recover more quickly than those with long T1's.
