WebT1 reflects the length of time it takes for regrowth of M z back toward its initial maximum value ( M o ). Tissues with short T1's recover more quickly than those with long T1's. Their M z values are larger, producing a stronger signal and brighter spot on the MR image. WebDec 21, 2024 · T1-weighted images are useful to visualize the tissues that predominantly contain fat ( bone marrow) since they produce a high T1 signal and appear white, which makes them easier to analyze. The tissues that contain more water (ligaments, cartilage, synovial fluid) produce a lower T1 signal and appear darker.
