4. Key Market Opportunity
One of the key opportunities in the Small Animal Imaging Market is the expansion of preclinical multimodal imaging adoption at pharmaceutical CROs that currently offer single-modality imaging services to pharmaceutical clients seeking comprehensive pharmacokinetic and pharmacodynamic imaging data packages. A significant proportion of pharmaceutical companies outsourcing preclinical small animal imaging receive single-modality data requiring separate optical BLI, micro-CT, and PET studies at different facilities with associated animal transfer, coordination, and timeline delays. CROs that install integrated multimodal small animal imaging platforms combining optical, CT, and nuclear imaging can offer comprehensive imaging data packages from a single animal cohort at a single facility with reduced study coordination complexity. Small animal imaging system manufacturers that develop scalable multimodal platforms for CRO installation, provide validated multimodal study protocols for pharmaceutical research applications, and offer instrument access models are positioned to expand multimodal imaging adoption at the growing preclinical CRO sector.

Three major forces are shaping the Small Animal Imaging Market trajectory over the forecast period:
IVIS Spectrum Technology Maintains Market Leadership in Small Animal Bioluminescence and Fluorescence Optical Imaging.Pharmaceutical and academic oncology researchers using luciferase-expressing tumour cell lines for in vivo xenograft tumour tracking and GFP-expressing cells for immune cell migration studies are specifying the PerkinElmer IVIS Spectrum. IVIS Lumina as the reference small animal optical imaging platforms with the largest validated bioluminescence reporter imaging evidence base. PerkinElmer continued commercial development of the IVIS Spectrum CT system combining optical and micro-CT imaging in 2024, maintaining IVIS market leadership in preclinical optical imaging. Expanding the portfolio to include combined BLI-CT imaging in a single session.
High-Field Preclinical MRI Technology Is Providing Anatomical and Functional Brain Imaging in Mouse Neurological Disease Models at Magnetic Fields Exceeding 9 Tesla.Neuroscience researchers studying Alzheimer's, Parkinson's, and psychiatric disease in transgenic mouse models are using high-field 9_4 to 14_1 Tesla small animal MRI systems to image brain anatomy. Additionally diffusion tensor tractography, functional connectivity, spectroscopy in genetically defined neurological disease mouse models. Bruker Biospin continued commercial development of the BioSpec and PharmaScan high-field preclinical MRI system series in 2024, maintaining its dominant position in high-field small animal MRI for academic neuroscience and pharmaceutical CNS research.
Low-Field Benchtop Small Animal MRI Technology Is Expanding MRI Access Beyond Specialised High-Field Research Facilities.Pharmaceutical and academic researchers seeking basic MRI anatomical and perfusion measurements without the infrastructure cost. Specialist expertise requirements of high-field superconducting magnet systems are adopting benchtop low-field MRI platforms that operate with permanent magnet technology at 0_3 to 1_5 Tesla field strength. Aspect Imaging and Pure Devices continued commercial development of benchtop low-field small animal MRI systems in 2024.

8. Segmental Analysis
By system type, micro-CT systems dominated the Small Animal Imaging Market in 2025, driven by universal application of three-dimensional anatomical imaging for tumour volume, bone morphology, and organ volume assessment across preclinical research. Pharmaceutical and academic researchers continue specifying dedicated small animal micro-CT as the primary preclinical imaging platform as three-dimensional anatomical datasets are required as standard efficacy and disease progression endpoints across oncology, bone, and metabolic models. Multimodal small animal imaging systems are the fastest-growing system type, driven by growing pharmaceutical and CRO adoption of combined PET-CT, optical-CT, and tri-modality platforms acquiring complementary functional and anatomical imaging from a single animal positioning. Pharmaceutical preclinical researchers and CRO imaging facilities are increasing multimodal system investment as combined imaging platforms reduce total study time per animal cohort and provide comprehensive imaging data packages from a single facility.
By application, oncology dominated the Small Animal Imaging Market in 2025, driven by the high volume of cancer drug discovery efficacy studies requiring tumour volume CT, BLI reporter imaging, and metabolic activity in xenograft models. Pharmaceutical oncology researchers continue generating the highest small animal imaging demand as tumour growth inhibition assessment by micro-CT and optical BLI is a mandatory endpoint in every in vivo xenograft and syngeneic efficacy study. Neuroscience is the fastest-growing application, driven by growing pharmaceutical CNS drug candidate brain penetration and target engagement assessment using preclinical MRI and PET as Alzheimer's disease, Parkinson's disease, and psychiatric disorder programmes expand. Pharmaceutical neuroscience researchers are increasing small animal MRI and PET demand as CNS drug programmes require quantitative brain pharmacokinetic and pharmacodynamic imaging biomarkers to predict clinical target engagement before advancing candidates to human trials.
