Healthcare Spending as a Catalyst for Small Animal Imaging (In-Vivo) Market Expansion

A significant factor propelling the small animal imaging (in-vivo) market’s growth is the rising expenditure in the healthcare sector worldwide. Healthcare spending encompasses both public and private costs as a percentage of GDP and reflects growing awareness around health management. This increased investment encourages self-care practices and the use of advanced imaging tools such as PET equipment in small animal imaging. By enabling real-time, noninvasive visualization of biological processes, small animal imaging supports faster drug development, deeper disease comprehension, and the formulation of more effective therapies. To illustrate, a May 2024 report from the UK’s Office for National Statistics highlighted that healthcare spending in the UK rose by 5.6% in nominal terms in 2023, with real-term growth of 2.8% in long-term health and social care expenditure in 2022. Such upward trends in healthcare funding are key growth drivers for the small animal imaging (in-vivo) market.

Innovations in Imaging Software Shaping Long-Term Trends in Small Animal Imaging (In-Vivo)

Leading companies in the small animal imaging (in-vivo) field are increasingly enhancing their software capabilities, particularly focusing on real-time kinetic analysis platforms. These advanced software solutions are designed to support more precise, quantitative, and high-throughput preclinical studies, especially in oncology and neuroscience. Unlike traditional static imaging snapshots, these platforms continuously capture dynamic bioluminescent signals over time, delivering richer data sets, improving reproducibility, and aiding in the accurate identification of peak signal phases. For example, in April 2024, US-based company Spectral Instruments Imaging released Aura 4.5, an updated version of its in vivo imaging software. This edition features a Kinetics mode that automates the acquisition of bioluminescent signals throughout their entire time course, including rise, plateau, and decay phases. The software then identifies peak intensity, helping researchers optimize sensitivity and biological accuracy while reducing manual labor. This upgrade is particularly valuable for longitudinal studies such as pharmacokinetics, gene expression, and infection models, enhancing workflow efficiency and data quality.
