Siemens Skyra 3T at Emory Brain Health Center

Shared Research/Clinical Skyra 3T MRI Scanner (BHI)

The shared MRI unit is a Siemens Medical Solutions (Malvern, PA) 3.0 Tesla Skyra MRI scanner, a full body scanner (70 cm bore) with Sonata gradient set (gradient amplitude of 40mT/m, maximum slew rate of 200T/m/sec).  The system is actively shielded and is equipped with 32 RF receiver channels and the total imaging matrix (TIM) suite.  Multiple coils are available for the systems, including

• a 12 channel head matrix coil
• two body matrix 8 channel flex coils
• an 8 channel head coil
• a 4 channel carotid coil
• a 24 channel spine coil

This scanner runs Siemens Syngo E11A software and has a number of advanced Siemens product sequences including

• parallel imaging
• SWI
• BLADE
• Diffusion Tensor Imaging (DTI) & Tractography
• Auto Align feature for reproducible slice positioning based on a 3D MR brain atlas
• BOLD imaging and in-line analysis suite with 3D PACE realtime motion correction
• advanced cardiac package, and single/multi-voxel spectroscopy

A number of advanced research sequences, including

• Vessel Size Imaging
• quantitative Arterial Spin Labeling
• Diffusion Spectrum Imaging (for High Angular Resolution Diffusion Imaging)
• Simultaneous Multi-Slice EPI (allowing for sub-second high-resolution whole-brain fMRI data acquisition)
• 4D phase contrast MR for measuring flow velocity
• displacement encoding (DENSE)
• multi-echo and ultra-short echo time sequences

are also available.
