Instruments

Sedecal Super Argus 4R PET/CT

The SuperArgus-4R system (Sedecal, Inc) offers multimodal PET/CT imaging in small animals including rodents, rabbits, ferrets, etc.  It incorporates a dual layer detector with LYSO and GSO crystals to provide PET imaging with high sensitivity and high resolution.  The integrated CT unit provides high resolution CT images for anatomical registration and cobined diagnosis.

Main Imaging Features

  • High Sensitivity: 11% at Center Point
  • High Resolution: 1mm at Center Point using 3D-OSEM reconstruction
  • Large PET field of view (FOV):  150mm bore size; 100mm axial FOV
  • Fast CT acquisition: ~2 min CT acquisition depending on the protocol

Sedecal SuperArgus Compace PET

The SuperArgus Compact PET system is a portable PET system with a small footprint.  It can conduct PET imaging on one mouse for each imaging session.  This PET system is featured with high sensitivity (>15%), which allows imaging with a very low dose of radioactivity.  The compact size enables the system to be placed on a mobile table for any imaging needs.

Study Initiation, Training and Scheduling

The majority of PET/CT imaging studies are conducted with SAI staff support.  To initate a PET/CT imaging study, please send an email to bricsai@med.unc.edu to schedule a meeting and register your project by following the study initiation link.  You can also see our study initiation page for more details.

Cost

The current internal rate for PET/CT imaging and staff support is $160/hr and $53/hr.  Imaging time is highly dependent upon the study protocol so please contact the SAI for budget information.  You can also see our rates at this link.
