Application of Intracavitary Three-Dimensional Ultrasound Volume Contrast Imaging Combined with Free Anatomy Section in the Diagnosis of Intrauterine Adhesions and Classification

Objective: To study the clinical value of three-dimensional ultrasound volume contrast imaging combined with free anatomy section in the diagnosis of intrauterine adhesions. Methods: 321 patients with suspected intrauterine adhesions admitted to Suzhou High-tech Zone People’s Hospital from July 2024 to July 2025 were selected. 94 cases were confirmed by hysteroscopy gold standard. All patients underwent separate examination of three-dimensional ultrasound volume contrast imaging (single examination) and a combined diagnosis scheme with free anatomy section (hereinafter referred to as combined diagnosis). The detection situation was analyzed, the diagnostic efficacy was calculated, and the results were compared with the gold standard to evaluate the advantages of combined diagnosis in disease classification. Results: The sensitivity and accuracy of the combined diagnosis were better than those of the single examination (P < 0.05). However, there was no significant difference in the detection rate of disease types between the two schemes (P > 0.05). Conclusion: The combination of three-dimensional ultrasound volume contrast imaging and free anatomy section can play a significant role in the diagnosis and classification of intrauterine adhesions, greatly improving the clinical detection rate.
