Abstract To investigate the clinical value of three-dimensional tomography ultrasonography imaging (TUI) combined with three-dimensional ultrasound comprehensive scoring for diagnosing intrauterine adhesions (IUA). Methods: The clinical data of 182 with suspected IUA from April 2021 to June 2022 were selected in the study. These patients had been diagnosed by TUI combined with three-dimensional ultrasound comprehensive scoring. Based on the hysteroscopy pathological diagnosis as the gold standard, the consistency of TUI combined with three-dimensional ultrasound comprehensive scoring for diagnosing IUA was analyzed. The characteristics of TUI were compared among the patients with mild IUA, the patients with moderate IUA, and the patients with severe IUA. Results: There were 92 patients with IUA diagnosed by hysteroscopy in the 186 patients, which including 32 cases with mild IUA, 34 cases with moderate IUA, and 26 cases with severe IUA. With the increase of the degree of IUA, the unsmoothness rate of endometrial edge of the patients in TUI examination increased (P＜0.05), but there were no significant differences in the other features, such as defects, cohesion, and calcification in TUI examination among the patients with different degree of IUA (P>0.05). The hysteroscopy results as the gold standard, the sensitivity, the specificity, the coincidence rate, the positive predictive value, the negative predictive value, and Kappa value of three-dimensional ultrasonic comprehensive scoring for diagnosing IUA were 95.7%, 92.6%, 94.1%, 92.6%, 95.6%, and 0.882, respectively, and the sensitivity, the specificity, the coincidence rate, the positive predictive value, the negative predictive value, and Kappa value of TUI for diagnosing IUA were 97.8%, 94.7%, 96.2%, 94.7% 97.8%, and 0.925, respectively. The sensitivity, the specificity, rate, the positive predictive value, the negative predictive value, and Kappa value of three-dimensional ultrasound combined with TUI for diagnosing IUA were 94.6%, 100.0%, 97.3%, 100.0%, 95.0%, and 0.946, respectively. Conclusion: TUI combined with three-dimensional ultrasonic comprehensive scoring method for IUA has high diagnostic value.
