Examples of typical clinical MRI. (A). Examples of typical clinical MRI. (A). Sagittal T1-weighted image. Note that fat (around scalp and neck) is bright and cerebrospinal fluid (CSF) is dark. (B) Axial proton density image. Note minimal contrast between grey matter and CSF. (C) Axial T2-weighted image. Note that CSF is bright. (D) Same image as (A) but following gadolinium administration. Note the dural venous sinuses appear bright due to T1 shortening. (E) Axial fluid attenuated inversion recovery image. Note suppression of the CSF signal. (F) Axial gradient echo T2* image. Same patient as in (C). Note the increase conspicuity of multiple dark foci due to magnetic susceptibility of haemosiderin deposition in a patient with amyloid angiopathy. Stuart Currie et al.
