All MRI experiments were performed on a 3.0T clinical MR scanner (Magnetom Trio scanner, Siemens Medical Solutions, Erlangen, Germany) employing 8-channel phased array receiver spine coil (body coil was used as the transmitter). 3D-T1ρ-weighted sagittal images were acquired with a 3D GRE ...
Sagittal images of the lumbar spine were obtained using T1-weighted FSE and fast T1-weighted FLAIR sequences. Both qualitative and quantitative analyses measuring the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and relative contrast (ReCon) between degenerative and metastatic ...

On the basis of preoperative sagittal MRI-T1WI, cartilage endplates were divided into anterior and posterior portions at the center of the disk and evaluated for discontinuity. Patient background characteristics, spinopelvic sagittal parameters, degrees of disk degeneration, and recurrence level were ...
