PRECLINICAL IMAGING FACILITY   

Preclinical imaging has become a powerful tool in biomedical research, allowing the non-invasive detection of biomarkers of disease. It enables the collection of anatomical, functional and dynamic imaging data from living experimental animals, including genetically modified models.

Preclinical imaging approaches provide the unique opportunity to perform longitudinal studies of the same animal, minimizing experimental variability and number of animals per study, refining preclinical research procedures in agreement with the 3Rs principles. Moreover, imaging represents a valuable translational tool between preclinical research and clinical trials. 

The facility for preclinical imaging at CEINGE hosts diagnostic equipments for structural and functional imaging in small rodents and morphofunctional characterization of animal models of human diseases, to bridge the gap between in vitro biomedical research and in vivo molecular research programs (development and testing of novel molecular probes).

The facility is equipped with:

      1. Ultrasound Biomicroscopy (UBM)

      2. Functional tomography (SPECT)

      3. Functional and structural tomography (PET-CT)

      4. High resolution CT (microCT)

      5. Dual Energy X-ray absorptiometry (DEXA)

      6. Laser Doppler Imaging (LDPI)

      7. Optical Imaging (bioluminescence, 2D and tomographic 3D fluorescence)

      8. Photoacoustic Imaging (PAI)

      9. High Field Magnetic Resonance (MRI)


-  VEVO 2100 (VisualSonics®) is a state-of-the-art high resolution ultrasound instrument designed to examine small laboratory animals, in vivo  and non-invasively. The high frequency of the ultrasound used (range 20-70 MHz) allows the qualitative assessment and accurate measurements of anatomical structures and the quantification of physiological data in adults, neonatal and embryonic small laboratory animals.

The Ultrasound Biomicroscopy operating modalities includes:

o   B-mode

o   M-mode

o   PW Doppler Mode

o   Tissue Doppler Imaging (TDI)

o   LV automated analysis, blood pressure and volume

o   advanced program of cardiovascular measuring

o   contrast mode program of acquisition and analysis

o   gas anesthesia system

o   microinjection system

Such applications allow studies in oncological (tumor growth, treatment effects), neuroscience, developmental biology and cardiovascular (morphofunctional, hemodynamic studies) research programs and echoguided microinjections.
