SPACE sequence
Also written as: SPACE — Sampling Perfection with Application optimized Contrasts using different flip angle Evolutions
Three-dimensional turbo spin echo sequence providing high-resolution isotropic imaging with excellent tissue contrast.
Full Definition
Sampling Perfection with Application optimized Contrasts using different flip angle Evolutions (SPACE) is a three-dimensional turbo spin echo sequence that provides high spatial resolution with isotropic voxels. This sequence allows multiplanar reconstruction in any orientation with consistent image quality and is particularly useful for detailed anatomical assessment of complex structures like the cranial nerves, inner ear, and spine. SPACE sequences can be optimized for T1, T2, or FLAIR contrast and offer superior signal-to-noise ratio compared to conventional 2D sequences.
Usage
Usage note: Siemens' proprietary implementation of 3D turbo spin echo.
