Objective: To analyze the value of three-dimensional ultrasound free anatomy imaging (OmniView) and tomographic ultrasound imaging (TUI) in evaluating intrauterine adhesions (IUA). Methods: A total of 112 patients with suspected IUA admitted to our hospital from March 2021 to March 2022 were selected, and all underwent OmniView and TUI scans. All patients were treated in our hospital. Taking the results of hysteroscopy as the gold standard, the detection performance of OmniView and TUI for IUA and its classification was analyzed. The receiver operating characteristic curve (ROC) was used to evaluate the performance of OmniView and TUI for IUA. Results: Hysteroscopy detected IUA in 98 cases and non-IUA in 14 cases. Among the adhesion types, 62 cases were central type, 11 cases were peripheral type, and 25 cases were mixed type. OmniView detected 93 IUA patients and 19 non-IUA patients; 59 central type, 10 peripheral type, and 24 mixed type. IUA detected 88 IUA patients and 24 non-IUA patients; 58 central type, 7 peripheral type, and 23 mixed type. According to the Kappa consistency test, the results of OmniView, TUI and hysteroscopy were generally consistent (Kappa=0.681, 0.625), and the results of combined detection and pathology were better (Kappa=0.813). According to the ROC model, both OmniView and TUI have certain diagnostic efficacy for IUA, and the combined detection efficacy is the highest. Conclusion: Both OmniView and TUI can be used to detect IUA and its classification. The combined detection of the two has the highest efficiency, and the combined detection results are in good agreement with the results of hysteroscopy, which can be used for clinical screening of IUA.
