Since the discovery of X-rays and its first use in imaging of a hand, bone tissue has been the chapter of interest in medical imaging. However, X-ray imaging poses limitations nowadays owing to the augmented complexity of implant scaffolds as well as with the advances in bone engineering. As a result, advanced follow-up imaging techniques are of paramount necessity for effective postoperative characterization. Moreover, it is also needed to search for non-invasive, high-sensitivity, and high-resolution structural, functional, and molecular imaging techniques such as acoustic, optical, magnetic, X-Ray, electron, ultrasound, and nuclear imaging, etc. as an alternative to normally used X-ray computed tomography. Further, enthusiastic preclinical scanners have turned out to be accessible, with sensitivity and resolution even superior to clinical scanners, as a consequence helping a rapid transformation from preclinical to clinical applications. Besides, recently, bone-specific probes and contrast agents are developing for better imaging tools in bone-tissue engineering applications. This review highlights such emerging preclinical imaging tools, each with its individual potencies and flaws, either used only or in combination. In particular, multimodal imaging will significantly add to improve the present understanding in the characterization of bone regenerative processes.
