Background To clarify the diagnostic usefulness of imaging modalities in pelvic tumor practice, inpatients having pelvic neoplastic disorders in our Institute were reviewed. Methods For a total of 1506 cases undergoing ultrasonography (US) only, those receiving a combined usage of computed tomography (CT) and US, magnetic resonance imaging (MRI) and US, and all three modalities, we compared the indications and selected imaging modalities in relation to the stream of therapeutic procedure. Results 324 cases (21.5%) judged to have no structural disease through imaging techniques at previous Hospitals underwent no further imaging examination. 420 cases (27.9%), most of which underwent surgery and/or radiation due to malignant lesions in the ovary and/or uterus, had US alone, and 564 cases (37.5%) had CT in addition to US. The main indications for ordering additional CT were suspected distant metastasis, including pelvic and paraaortic lymphnodes. 95 patients (6.3%) had US and MRI under indication of tissue characterization in tumors. 103 cases (6.8%) with difficulties in diagnosis had all modalities; US, CT and MRI. In 324 cases without imaging modalities, 60 cases (18.5%) undergoing operative procedure were those with cervical neoplasm, and 70.0% of the cases followed by chemotherapy were for ovarian cancer. Such will be further discussed in detail.
