ObjectiveTo explore the accuracy of 64-slice multislice computed tomography with ovarian vein tracking technique in identification of surgically transposed ovaries.MethodsThe CT and clinical data of 84 patients with ovarian transposition were retrospectively analyzed. Two radiologists completed the assessments independently. The CT data were analyzed twice. During the first assessment, transposed ovaries were identified on both sides of the lower paracolic gutters on enhanced axial CT images. The second assessment was carried out two months later. The presence or absence of transposed ovaries was identified by ovarian vein tracking technique. If the adjacent colon of the transposed ovary was not filled with contrast agents, two radiologists measured the CT values of the solid-appearing area of the transposed ovary and the wall of the adjacent colon.Results84 patients with cervical cancer underwent ovarian transposition. There were 98 transposed ovaries and 70 non-transposed ovaries. The sensitivity, specificity and accuracy of the two assessments in identification of the ovaries were 72.4%, 98.6%, and 83.3% (first assessment), and 93.9%, 100% and 96.4% (second assessment). The sensitivity and accuracy of the two assessments were significantly different (p < 0.01). The solid-appearing area of the transposed ovaries and the wall of the adjacent colon in 33 cases showed soft tissue density. The CT values were (44.44 ± 5.78) HU and (44.50 ± 6.30) HU. The CT values were no significant difference (p > 0.05).ConclusionOvarian vein tracking technique can accurately identify the unmarked transposed ovaries, which is crucial in the diagnosis of abdominal/pelvic lesions.Copyright © 2018.
