3-dimensional reconstruction of ultrasound images of the uterine cavity.

We report our experience of 3-dimensional (3-D) reconstruction of ultrasound images of the uterine cavity. This is the first time that mapping of the contours of the uterine cavity with 3-D reconstruction has been achieved using standard clinical equipment for image acquisition. Ultrasound contrast hysterography was performed on 10 patients using both negative and positive intrauterine contrast media. 3-D image acquisition was performed during uterine cavity distension. The manipulation of the 3-D data sets is described and examples are shown. We believe that in some circumstances 3-D reconstructed images may be easier to interpret than 2-dimensional ultrasound images. We anticipate that this new technique will have a role in the preoperative assessment of uterine fibroids and endometrial polyps.
