Advanced 3D Imaging Package
3D DESS for high-resolution 3D studies of joints with excellent T1 and T2 contrast. DESS is a double echo gradient sequence in which a FISP (transversally rephased gradient echo) and a PSIF (RF-refocused gradient echo) echo are simultaneously acquired and added, resulting in an increased signal-to-noise ratio.
3D CISS for excellent very high resolution studies, especially useful in inner-ear examinations.
These Advanced 3D data sets provide very thin contiguous slices with high signal-to-noise ratio which are also well suited to MPR post-processing along straight (oblique or double oblique) or curved lines. In some cases such as MR Myelography or inner ear work, the MIP algorithm also provides very useful information.
