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.
