The preclinical imaging (In-VIVO) market has been segmented by product, application, end-user, and geography. In terms of product, the preclinical imaging market is sub-divided into imaging modalities and reagents. The imaging modalities segment is classified into single photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), micro computed tomography (microCT), positron emission tomography (PET), optical imaging, and magnetic particle imaging (MPI). MRI and PET are highly used in preclinical imaging. Sometimes, combination of imaging techniques are used for good quality results such as combination of PET and CT. The reagents segment is classified into fluorescent imaging reagents, bioluminescent imaging reagents, PET radioactive tracers, MRI contrasting reagents, X-ray CT contrasting reagents, and ultrasound contrasting reagents. In terms of application, the preclinical imaging market is classified into research and development and drug discovery. In terms of end-user, the market is classified into pharmaceutical companies, biotech companies, and research institutes. Geographically, the preclinical imaging market is classified into North America, Latin America, Europe, Asia Pacific, and Middle East & Africa.
