Using AMRIS • All instruments have user fees. We must cover all costs without making a profit. • Current fees are posted on the AMRIS web site: • http: //www. mbi. ufl. edu/facilities/amris/ • Most “routine” service jobs can be handled by AMRIS staff • New development or very sophisticated applications are done in collaboration with expert faculty groups • We budget for approximately 40 external user projects and 10 pilot studies

Stem cell tracking in live mice at 750 MHz G. A. Walter, E. W. Scott, and N. E. Bengtsson, UF; S. Santra; University of Central Florida Tibia Window w/ MRI micro-coil for Confocal and MRI Imaging Optical and magnetic resonance imaging track labeled stem cells within the bone marrow of mice following femoral arterial delivery of bone marrow stem cells. The bone chamber window allows for the optical tracking of transplanted cells prior to high resolution MRI and does not interfere with MRI signal acquisition or have a negative impact on the image quality of MR images. Ultrahigh resolution in vivo MR images obtained following the arterial delivery of labeled bone marrow cells. Images are reconstructed at a resolution of 21 x 38 μm 3 and were acquired in 90 minutes. Dashed red circles indicate areas of image contrast attributed to single cells in both the muscle and the bone marrow. The dashed green circle highlights an area with accumulation of labeled cells. The green legend (line) in A is 150 μm.

Renovation of the AMRIS Facility Current facility is 12 years old and at capacity. Any new instruments could not currently be housed in the AMRIS wing Specific Aim 1: Reconfigure internal walls within the AMRIS wing to allow addition of new instruments. Specific Aim 2: Renovate HVAC support and cryogen delivery within the AMRIS facility Air handling systems have also improved since the construction of the AMRIS wing. Specific Aim 3: Provide centralized animal staging for imaging and spectroscopy studies

AMRIS plans moving forward • Maintain existing overall general external user program at about the current levels (slight increase). • Continued development under 3 technical cores with faculty leaders to better grow unique areas of strength. • Build the RF core strengths and continue integrating with Tally RF group. Priorities: – Large volume coils – Multi-nuclear coils – Better 1 H coils/probes for imaging at 750 MHz – Better live animal capabilities
