T1 vs t2 radiopaedia
WebWhen an MRI sequence is set to produce a T1-weighted image, it is the tissues with the short T1 values that produce the highest magnetization and which appear brightest in the image. A T1-weighted sequence produces T1 contrast mainly by de-emphasizing the T2 contributions. This is normally achieved by using short repetition times TR (300-600ms ... WebJan 14, 2024 · Specifically, in the coronal and sagittal planes, T1, T2, and intermediate-weighted proton density FSE sequences are often utilized. Fat saturation is employed on some of the fluid-weighted sequences to better detect the presence of edema in the soft tissues or bone marrow.
