MR Imaging of the Inner Ear/ IAC at Siemens 3T Skyra w/head neck 20ch. CISS vs T2-w SPACE. A few key factors which are advantages of T2-w SPACE: 1. flow void (blue arrows) 2. no banding artifacts (red arrow) 3. higher resolution (green arrow) 4. "Clear" contrast CISS --> 0.6mm isotropic approx. 5min. T2w SPACE --> 0.5mm isotropic approx. 5min.
