Modern techniques can cut the number of animals used and improve data quality.
Scientists are increasingly turning to non-invasive imaging to further the '3Rs' of work in animals — replacement, refinement and reduction. Although the use of animals in modern medicine and biology is essential, researchers are actively working to reduce the numbers used and improve on how they are used.
Medical technologies, such as computed tomography (CT) scans and magnetic resonance imaging (MRI), together with imaging techniques specific to biology, can assist in this.
