Three-dimensional ultrasonographic reconstruction of the uterine cavity: toward virtual hysteroscopy?

The aim of this study was to evaluate the possibility of diagnosing intrauterine abnormalities, using a "virtual endoscopy" technique based on 3D hysterosonographic data. Five patients who presented intrauterine abnormalities (polyps, n=2; leiomyomas, n=3) underwent 3D transvaginal hysterosonography. The 3D data set was subsequently processed by using a proper software that creates virtual endoscopy images. After ultrasonographic examination, patients had a conventional hysteroscopy. In all patients intrauterine lesions were easily and reliably detected by computer-reconstructed 3D hysterosonography. Images obtained by this "virtual hysteroscopy" technique, including fine intrauterine details, were remarkably comparable to those obtained by conventional hysteroscopy. The results of this pilot study indicate that computerized reconstruction of 3D hysterosonography offers adequate visualization and characterization of intrauterine lesions.

“…A movie is constructed in which the observer images the digitally stored sonohysterographic data with a virtual endocavitary camera beginning with 1 cornu, moves into the fundus, proceeds to the other cornu, and turns around toward the cervix. 29 The contrast between the hypoechoic saline-filled cavity and the surrounding uterine walls makes the uterus a good structure for virtual endoscopy with the use of sonohysterographic data. In this preliminary work, the data were analyzed offline, and the image manipulation was quite time-consuming.…”

Objective. The aim of this work was to review the technical aspects and clinical applications of threedimensional ultrasonography in gynecologic imaging. Methods. With the use of a computerized database (MEDLINE), articles on three-dimensional ultrasonography were reviewed. Other pertinent references were obtained from the references cited in these articles. In addition, we reviewed our own clinical experience over the past 7 years. Results. Numerous applications of three-dimensional ultrasonography have been reported, including imaging of the uterus, the endometrial cavity, adnexa, and the pelvic floor and color and power Doppler applications. The accuracy of volume calculations and the networking opportunities with three-dimensional ultrasonography have also been reported. Technical problems and limitations of this technique are summarized. Conclusions. Three-dimensional ultrasonography has proved to be a useful imaging tool for clinical problem solving in gynecology, especially in imaging the uterus and uterine cavity.

“…The use of cine loops to ‘fly through’ the vessels in many organs ranging from the brain to the kidneys suggest a whole new dimension for noninvasive vascular imaging of the future. Currently these cine loops can be viewed on the world wide web [30]. Whilst this web‐based image can be used to augment this manuscript, it foretells a substantial addition in our ability to communicate clinical images and information.…”

Abstract. Potchen EJ (Michigan State University, Michigan, USA). Prospects for progress in diagnostic imaging (Internal Medicine in the 21st Century). J Intern Med 2000; 247: 411±424.New fast-imaging MRI systems designed specifically for cardiac magnetic resonance enable new applications of noninvasive vascular imaging. The use of functional MRI and diffusion tensor imaging to map brain function and structure offers a new dimension to an understanding of the human condition. Clinical applications of functional MRI will influence many specialties including surgery, education, and rehabilitation. Functional imaging has the potential to visualize the regional concentration of specific proteins. This imaging at the level of molecules may be possible by use of a contrast material whose signal is changed by local enzymatic activity. The three-dimensional digital data collected in modern imaging techniques allow for virtual endoscopy in the respiratory, alimentary, and cardiovascular systems. Virtual endoscopy may replace many of the more invasive diagnostic methods in the near future. The measurement of clinical decision-making through observer performance studies better informs both the physician and the patient on how to improve upon the quality of clinical practice. These prospects for progress reinforce diagnostic imaging as a cornerstone in medical informatics. The history of creating images used in medicine reveals the invention of diagnostic tools which may provide new information but premature use can result in improper application of a poorly understood technology. Research into the use of new technology may be as important as the technology itself in improving the human condition.
