A total of 100 cases of normal endometrium were used as the control group, including 52 cases in the proliferative stage and 48 cases in the secretory stage. Transvaginal real-time shear wave elastography was performed in all four groups.Results: Emean, Emax and Esd were expressed as the average standard deviation. Among the control group, the results were 26.24± 9.74, 38.09± 9.18, and 4.25± 2.73 kPa, respectively, in the proliferative endometrium cases and 12.51± 7.46, 27.22± 11.32, 4.40± 2.52 kPa, respectively, in the secretory endometrium cases. Among the experimental group, the result was 15.68± 8.18, 27.28± 10.28 and 3.62± 1.81 kPa respectively in the endometrial polyps cases; 21.20 ± 12.57, 36.32 ± 15.04, and 5.09 ± 3.93 kPa in the endometrial hyperplasia cases; 49.36± 25.51, 86.66± 42.27 and 14.86± 10.63 kPa in the endometrial cancer cases. The difference was statistically significant (P < 0.05). When the truncation values of Emean, Emax and Esd were 28.50, 52.45 and 9.05 kPa, respectively, to distinguish between normal endometrium and endometrial cancer, Emax has the highest diagnostic value.Conclusion: Real-time SWE technology might be used as an auxiliary method in the diagnosis and differential diagnosis of endometrial cancer. More quantitative indicators are conducive to diagnosis.Keywords: ultrasound, endometrial lesions, real-time shear wave elastography, differential diagnosis
