What we do

The Translational Imaging Shared Resource (TISR) at Roswell Park Comprehensive Cancer Center provides specialized preclinical imaging services including image acquisition, quantitative image analysis, multidimensional renderings and data sets for research purposes.

Our mission is to:

  • Provide the necessary intellectual and physical resources relating to non-invasive in vivo imaging.
  • Develop novel preclinical imaging techniques to meet the needs of researchers and provide insight into various biological processes involved in cancer progression.
  • Enable the conduct of preclinical trials of experimental therapeutics in preclinical models.
  • Establish technology platforms that allow translation of imaging techniques evaluated in preclinical models to the clinical arena.

The Translational Imaging Shared Resource (TISR) at Roswell Park Comprehensive Cancer Center provides scientific and technical services pertaining to multimodality image acquisition, quantitative image analysis, multidimensional renderings and visualization of imaging data sets.

The resource is equipped with (a) a Bruker 7.0 Tesla MRI, (b) a preclinical ultrasound/photoacoustic imaging system (Vevo® LAZR, VisualSonics), (c) a combined bioluminescence/fluorescence imaging system (IVIS Spectrum, Perkin-Elmer) with tomographic and multi-spectral capabilities, (d) a bioluminescence imaging system (IVIS-50, Perkin-Elmer), and (e) a planar X-RAY imaging system (MX-20, Faxitron). The resource offers a wide range of anatomical and functional imaging services including disease monitoring, tumor microvascular/ oxygenation assessment and novel imaging agent development. Resource staff also facilitate multimodality imaging research through collaborative interactions with other core resources or regionally available instrumentation (e.g., microPET imaging, State University of New York at Buffalo, Department of Nuclear Medicine).
