The SAIL has been conceived as a pre-clinical imaging core resource whose primary mission is to support research using small animal models as surrogates for testing and exploring human diseases, diagnoses, treatments, and physiology.
Instrumentations
- microPET Siemens Focus 120 . High-resolution, small-animal PET scanner that combines high spatial resolution (<1.3 mm) and high sensitivity (>7%) with a bore size (12 cm diameter and 7.6 axial length) that is optimized for imaging mice and rats. For radioactive agents, we are routinely imaging 18F 2-fluoro-2-deoxy-D-glucose (FDG) and 18F sodium fluoride (NaF). We have imaged 18F fluorothymidine (FLT) and are in the process of developing the capability to image 18F FHBG as well as an 18F labeled αVβ3 imaging agent.
- Imaging and Diagnostic Benefits: PET systems allow imaging of metabolic processes relative to anatomical images. SPECT and PET produce a variety of functional images. This has made PET and SPECT invaluable tools for the study of animal models of human disease; transgenic animals; pharmacological agents in drug development; novel drug delivery and gene therapy approaches; new molecular imaging assays; and new radiotracers for use in diagnostic imaging. PET and SPECT have been invaluable in understanding, diagnosing or staging of cancers and neurological diseases such as epilepsy.

- ADC/XRE Unicath SP fluoroscope. Large-animal fluoroscopy is available using an ADC/XRE Unicath SP single-plane cardiovascular digital angiography unit with a high-resolution fluoroscopy tube, an advanced image intensifier with full-frame zoom, and an image analysis workstation.
- Small solid state gamma camera. For planar Imaging.
- Faxitron MX-20 Specimen Radiograph System. It provides high-resolution x-ray images of mice and small rats (the system includes a gas anesthesia system) as well the ability to obtain radiographic images of excised tissue samples. The x-ray tube can operate at voltages ranging from 10 to 35 kVp with a maximum tube current of 300 A. The focal spot is 20 um allowing for very high spatial resolution. The system is mounted on a cart and can be moved around the laboratory as necessary.
