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.
The conventional method of performing laser-induced fluorescence, as well as other types of spectroscopic measurements, such as infrared, ultraviolet-visible spectroscopy, phosphorescence, etc., is to use a small transparent laboratory vessel, a cuvette, to contain the sample to be analyzed.

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).
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.
Propidium iodide (or PI) is a fluorescent intercalating agent that can be used to stain cells and nucleic acids.PI binds to DNA by intercalating between the bases with little or no sequence preference.
Fluorescence imaging photographs fluorescent dyes and fluorescent proteins to mark molecular mechanisms and structures. It allows one to experimentally observe the dynamics of gene expression, protein expression, and molecular interactions in a living cell. [3] It essentially serves as a precise, quantitative tool regarding biochemical ...
As fluorescence is a special case of luminescence, digital X-ray imaging is conceptually similar to digital gamma ray imaging (scintigraphy, SPECT, and PET) in that in both of these imaging mode families, the information conveyed by the variable attenuation of invisible electromagnetic radiation as it passes through tissues with various ...
Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect.Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission.
