Core for Advanced Magnetic Resonance Imaging Facilities and Equipment


Project Support and Technology


The Core for Advanced Magnetic Resonance Imaging (CAMRI) is to supports biomedical research projects that use MRI to further our understanding of anatomy, function and physiology. The core offers MRI technologies to the Houston and surrounding research communities. We educate and train the community on the use of these technologies and support the efficient use of the core's resources.


Major Equipment


Siemens MRI Scanners - 3 Tesla

  • Scanner 3T-4 is a 64-channel system (Prisma Fit) with 20-Ch and 64-Channel head coils
  • Scanner 3T-5 is a 32-channel system with 12-Ch and 32-Ch head coils
  • CP Head Coil, Body Matrix Coil, 15-channel knee coil, and spine coils are available on some scanners
  • Full neurological scanning software including BOLD, DTI and MRS (VB17 and E11b software versions)
  • Siemens Master Research Agreement in place with generalized brain-imaging research addendum
  • C2P collaboration agreements in place with UMinn, MGH, CMRR and UCLA to provide access to multiband and pCASL WIP sequences
  • Spiral fMRI sequences developed in collaboration between Siemens and the PI
  • Dual-network cards to facilitate real-time fMRI
