Preclinical imaging is the visualization of living animals for research purposes, [1] 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.
Fluorescence imaging with one nanometer accuracy (FIONA): utilizes total internal reflection illumination to reduce noise and increase brightness of fluorophores [5] Calcium imaging: technique that utilizes fluorescent molecules called calcium indicators that change in fluorescence when bound to Ca 2+ ions. This is a key part in seeing when ...
Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [4] [5] It generally refers to fluorescence confocal microscopy, although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
Imaging Core: The Advanced Imaging Core at MMRI was developed to facilitate the non-invasive analysis of preclinical models of disease. [3] Equipment includes: Perkin Elmer IVIS Spectrum – 2D and 3D optical imaging; Perkin Elmer Quantum GX microCT – x-ray computed tomography imaging; Visual Sonics Vevo 3100 Ultrasound – high frequency ...
High resolution 99m Tc-MDP mouse scan acquired with a stationary SPECT system: animated image of rotating maximum intensity projections.. Preclinical or small-animal Single Photon Emission Computed Tomography is a radionuclide based molecular imaging modality for small laboratory animals [1] (e.g. mice and rats).
Newly developed fluorescent proteins that absorb in the near-IR range (e.g. red fluorescent protein) allow imaging deep inside tissues. [ 9 ] [ 58 ] [ 59 ] MSOT based on in situ expression of fluorescent proteins can take advantage of tissue- and development-specific promoters, allowing imaging of specific parts of an organism at specific ...
In drug development, preclinical development (also termed preclinical studies or nonclinical studies) is a stage of research that begins before clinical trials (testing in humans) and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals.
Two-photon excitation microscopy of mouse intestine.Red: actin.Green: cell nuclei.Blue: mucus of goblet cells.Obtained at 780 nm using a Ti-sapphire laser.. Two-photon excitation microscopy (TPEF or 2PEF) is a fluorescence imaging technique that is particularly well-suited to image scattering living tissue of up to about one millimeter in thickness.
