How can we identify a T1-weighted or T2-weighted image on MSK MR Imaging? Unfortunately, fat is not a good indicator because, due to J-coupling, it will be ("abnormally") bright on all FSE pulse sequences. The first key point is that fluids will be hyperintense on T2-w image (yellow arrow) and hypointense on T1-w image. The second key point is that muscles will be brighter on T1-w image (green arrow) compared to T2-w image.
