WebApr 12, 2024 · The most frequently used MRI sequences for the brain examination are T1-weighted and T2-weighted, as well as FLAIR. Roughly speaking, T1w sequences are very useful to examine the normal anatomy of the brain, while T2w is mostly used to detect the pathological changes in the neural tissue. WebA combination of standard T1 images and STIR images can be compared to determine the amount of fat or water within a body part; In these MRI images abnormal signal is seen in the vertebral bodies and intervertebral disc; Abnormal low signal on the T1 image and abnormal high signal on the STIR image – indicates abnormal fluid
WebApr 4, 2024 · On T1-weighted MR images, the normal pancreas has the highest signal intensity relative to other parenchymal organs, because of its high protein and rough endoplasmic reticulum content, followed by the liver, then the spleen. On T2-weighted images, the pattern is reversed; the normal spleen has higher signal intensity than the … WebT1 images are typically used for anatomic information, as they are also highly sensitive for paramagnetic contrast media, fat, fluids with high protein content and subacute …
