Optical imaging of living animals is a unique method of studying the dynamics of physiological and pathological processes at a subcellular level. One‐shot acquisitions at high resolution can be achieved on exteriorized organs before animal euthanasia. For longitudinal follow‐up, intravital imaging can be used and involves imaging windows implanted in cranial, thoracic or dorsal regions. Several imaging window models exist, but none have proven to be applicable for long‐term monitoring and most biological processes take place over several weeks. Moreover, none are compatible with multiple imaging modalities, meaning that different biological parameters cannot be assessed in an individual animal. We developed a new dorsal chamber that was well tolerated by mice (over several months) and allowed individual and collective cell tracking and behaviour analysis by optical imaging, ultrasound and magnetic resonance tomography. This new model broadens potential applications to areas requiring study of long‐term biological processes, as in cancer research.
