Tissues with a long T2 relaxation time show hyperintense signal while those with short T2 relaxation time show hypointense signal on T2W images.1 A hypointense signal on T2W sequences is the result of T2 shortening.1 An increase in local inhomogeneities in tissue leads to T2 shortening.

Therefore, CSF is bright and also any part of the normal brain (gray matter) or abnormal brain (edema, ischemic stroke, demyelination,tumor, etc) that has high water concentration will be bright.
