The CISS (Constructive interference in steady state) sequence is a gradient-echo MRI sequence that offers the advantages of a high signal-to-noise ratio, a high contrast-to-noise ratio, and intrinsic insensitivity to motion[^1].
Applications
The image contrast in a CISS sequence is determined by the T2\/T1 tissue ratio, thus providing excellent contrast between Cerebrospinal fluid and other structures in intracranial imaging. Due to this property, the CISS sequence is used to visualize structures surrounded by cerebrospinal fluid[^1].
