Preclinical imaging is the visualization of living animals for research purposes, such as drug development. Imaging modalities have long been crucial to the researcher in observing changes, either at the organ, tissue, cell, or molecular level, in animals responding to physiological or environmental changes. Imaging modalities that are non-invasive and in vivo have become especially important to study animal models longitudinally. Broadly speaking, these imaging systems can be categorized into primarily morphological/anatomical and primarily molecular imaging techniques. Techniques such as high-frequency micro-ultrasound, magnetic resonance imaging (MRI) and computed tomography (CT) are usually used for anatomical imaging, while optical imaging (fluorescence and bioluminescence), positron

  • Obrazowanie przedkliniczne – pojęcie odnoszące się do obrazowania medycznego przeprowadzanego w fazie przedklinicznej badań eksperymentalnych. Może być przeprowadzane in vitro na komórkach i tkankach wyizolowanych z organizmów zwierząt lub in vivo na żywym organizmie. Stosuje się również odmianę in vivo nazywaną ex vivo, która od in vivo różni się tym, że materiał biologiczny jest pozyskiwany z żywego organizmu w celu jego modyfikacji in vitro i ponownego podania z powrotem do organizmu, z którego go pozyskano. W odróżnieniu od klasycznego obrazowania diagnostycznego (diagnostyki obrazowej), obrazowanie przedkliniczne skupia się głównie na wykrywaniu zaburzeń na poziomie molekularnym, które stoją u podstaw rozwoju procesów chorobowych, a nie na widocznych końcowych efektach tych procesów.

  • Preclinical imaging is the visualization of living animals for research purposes, such as drug development. Imaging modalities have long been crucial to the researcher in observing changes, either at the organ, tissue, cell, or molecular level, in animals responding to physiological or environmental changes. Imaging modalities that are non-invasive and in vivo have become especially important to study animal models longitudinally. Broadly speaking, these imaging systems can be categorized into primarily morphological/anatomical and primarily molecular imaging techniques. Techniques such as high-frequency micro-ultrasound, magnetic resonance imaging (MRI) and computed tomography (CT) are usually used for anatomical imaging, while optical imaging (fluorescence and bioluminescence), positron emission tomography (PET), and single photon emission computed tomography (SPECT) are usually used for molecular visualizations. These days, many manufacturers provide multi-modal systems combining the advantages of anatomical modalities such as CT and MR with the functional imaging of PET and SPECT. As in the clinical market, common combinations are SPECT/CT, PET/CT and PET/MR. (en)
