CENABIO-UIPA, located on the ground floor of the UIPA building, has a trimodal equipment (Triumph LabPET 8, Gamma Medica), which integrates three imaging techniques in a single device: PET (positron emission tomography), SPECT (single photon emission tomography) and CT (computed tomography). This combination allows for the rapid and efficient acquisition of anatomical and functional images, facilitating the fusion of information for translational studies..
Computed Tomography (CT)
Imaging technique that uses X-rays to generate 3D images with high spatial resolution, ideal for visualizing bone structures. For soft tissues, the use of contrast agents may be necessary to improve definition.
Molecular Imaging (PET/SPECT)
Functional techniques that detect biological processes at the cellular and molecular level, using radionuclides as metabolic tracers.
The image is formed by detecting gamma radiation emitted by radiotracers (molecules labeled with radioisotopes), administered in minimum concentrations. Pharmacokinetics and selective uptake by tissues provide quantitative and functional data.
