WebT1-weighted (T1; short TR and short TE): Provides good contrast between gray matter (dark gray) and white matter (lighter gray) tissues, while CSF is void of signal (black). Water, such as CSF, as well as dense bone and air appear dark. Fat, such as lipids in the myelinated white matter, appears bright.

WebMar 7, 2024 · Acoustic shadowing (sometimes referred to as posterior acoustic shadowing) is a form of ultrasound artifact. It is characterized by the apparent lack of signal deep to an imaged tissue interface, due to all (or nearly all) of the transmitted sound wave being being reflected back to the transducer or absorbed by the tissue. It commonly occurs ... T1 sequences will have grey matter being darker than white matter. T2 weighted sequences, whether fluid attenuated or not, will have white matter being darker than grey matter.
