Effective cartilage imaging and whole organ joint assessment requires both high isotropic resolution and fat suppression or separation. bSSFP imaging provides high intrinsic signal strength but TR constraints limit the achievable resolution. Presented here is an approach where a standard bSSFP has been implemented with using the previously developed 3D radial out and back VIPR trajectory modified to create 4 echo times for an IDEAL implementation . Here we demonstrate the high performance capabilities of this method at 3T with high resolution, 3D, T2 weighted knee imaging.
