• W3187145571 abstract "This study aimed to explore the diagnosis of endometrial polyps (EMP) by ultrasound imaging based on multi-operator algorithms combined with hysteroscopy. This study is the first to investigate the resolution of the ultrasound adaptive beamforming algorithm (MOAD), after which the proposed algorithm was applied to ultrasound diagnosis of 102 patients with EMP and pathologically diagnosed with vaginal irregular bleeding, and the evaluation efficacy of the MOAD algorithm based on EMP was compared. The resolution of the MOAD-based imaging algorithm (0.0645) was significantly lower than that of the diagonal loading operator (0.1475), the symbol coherence coefficient operator (0.1342), and the generalized coherence factor operator (0.1234), with significant differences ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M1> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). The proportion of patients with EMP aged 46–55 years was the largest (55.9%). There were 64 cases of EMP that produced complications, of which the proportion of patients with uterine fibroids (41.52%), abnormal uterine bleeding (76.24%), and menstrual changes (42.57%) was relatively large. Patients with nonfunctioning polyps accounted for the largest proportion (84.46%), followed by those with basal polyps (76.24%), and the difference was statistically significant ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M2> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). The positive cases of EMP detected by ultrasound imaging (38 cases) were significantly lower than those with pathological diagnosis (94 cases), and the difference was statistically significant ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M3> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). The SE, SP, FNR, and FPR of EMP diagnosed by ultrasound imaging combined with hysteroscopy were 64.45%, 84.67%, 35.48%, and 13.36%, respectively. It has high diagnostic value compared with single ultrasound imaging diagnosis, and the difference was statistically significant ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M4> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). In conclusion, the imaging based on the MOAD algorithm is obvious and the pixel resolution can be successfully improved. The diagnostic value of ultrasound combined with hysteroscopy for EMP was better than that of ultrasound alone ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M5> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ), and it had a high diagnostic value." @default.
