Ultrasound real-time imaging is a technique that may help make a differential diagnosis between cysts and granulomas by revealing the nature of the content of a bony lesion. This technique may have further applications in the study of other lesions of the jaws.

Ultrasound real time imaging is a promising diagnostic technique in endodontology, but further work is required to refine the process.

Radiographs in endodontics are of importance for the study and management of periapical lesions. With the development of advanced systems in traditional radiology, new and more accurate imaging techniques are constantly under investigation. Computerized tomography, magnetic resonance and real‐time echotomography have been introduced in recent years to the field of endodontics: they may have advantages over conventional techniques for the amount of detailed information they can provide on specific cases. This paper reviews these new imaging techniques with respect to their possible role in the diagnosis and management of periapical lesions.

The evaluation of inflammatory activity in Crohn's disease (CD), a crucial aspect of treatment planning and monitoring, is currently based on a sum of clinical data and imaging findings. Among the contrast enhanced cross-sectional imaging techniques (CE-US, CE-CT, CE-MR), CE-US is less invasive, more comfortable for the patient, and has significant diagnostic accuracy. In addition, it is a portable, easily repeatable, well tolerated, and ionizing radiation-free imaging modality. CE-US has been introduced as effective method in the quantitative and qualitative evaluation of CD inflammatory activity. CE-US might help in characterizing bowel-wall thickening by differentiating inflammatory neovascularisation, edema, and fibrosis. The recent chance to evaluate the bowel-wall stiffness by US elastography imaging could allow further assessment of fibrosis that characterizes the evolution of the inflammatory activity.

US-CPD in endodontics may be a helpful tool to identify healing processes after endodontic treatment and to understand the behavior of different forms of AP.

Agent detection imaging with Levovist increased diagnostic confidence in the characterization of focal hepatic lesions as compared with standard sonography.
