Study Objective; We produced virtual hysteroscopy (VH) images from the images obtained after expanding the uterine cavity of patients with submucosal myomas and performing Multidetector-row Computed Tomography(MDCT) scans, and assessed them in comparison to hysteroscopic imaging and in relation to the advantages of VH. Setting; Tokyo medical university hospital department of obstetrics and gynecology. Patients; 89 patients with submucosal myomas treated by endoscopic surgery. Measurements and main results; The expandability of the uterine cavity by CO_2 gas was favorable in all 89 cases in which imaging was performed, and it was possible to obtain clear VH images. The sites of origin of the submucosal myomas were clearly visualized, their imaging was consistent with that the imaging by hysteroscopy, and as a method of establishing the orientation of the uterine cavity it was possible to obtain a greater amount of information than by hysteroscopy. Conclusion; Although the invasiveness of the exposure and contrast medium cannot be denied, the possibilities and indications of VH, which by expanding and visualizing the uterine cavity enables the acquisition of navigation images of the uterine cavity, which varies in morphology from patient to patient, are expected to continue to expand.
