Technological advances in IVM include ultrafast tunable infrared lasers, super-resolution imaging in vivo, and better access to all organs by improved optics or motion-correction mechanisms. Optical clearance methods for use in OPT and SPIM allow imaging entire organs and organisms (such as mice or insect vectors), while achieving cellular and subcellular resolution. OAI combines optics and acoustics via the thermoelastic effect to investigate molecular mechanisms. Key advances in MRI include improved contrast agents, multimodal mesoscopic imaging, and functional MRI to visualize the metabolic function of tissues. Developments in bioluminescence imaging include red-shifted probes with high sensitivity; a larger diversity of probes with emission peaks at various wavelengths; ultrabright probes, and the use of BRET in vivo. X-ray-based and gamma-ray-based imaging platforms are noninvasive and enable the study of anatomical structures, metabolism, biochemical composition of tissues, and dynamics.
