3D T1ρ mapping sequence allows rapid acquisition of the entire volume data of each anatomic region, including major joint tissues. In this work, we propose the accelerated high-resolution 3D T1ρ-mapping of the knee-joint using motion-robust interleaved spin-lock acquisition with Compressed SENSE. We compared the T1p mapping with in-plane resolution of 0.5mm2 with different C-SENSE reduction factors (3 and 4.2). There are no clear differences between two image datasets, hence we applied C-SENSE reduction factor of 4.2 (5min48s) for clinical scans, acquiring motion-insensitive high-quality isotropic images less than 6 minutes.
