Clinical Efficacy of Color Doppler and High-Frequency Ultrasound in the Diagnosis of Benign and Malignant Breast Nodules
Objective To explore the clinical value of color Doppler and high-frequency ultrasound in the diagnosis of benign and malignant breast nodules.Methods 68 patients with breast nodules admitted to Luoyang Yiluo Hospital from January 2022 to February 2023 were selected as the research subjects.Pathological examination results were used as the gold standard.All patients underwent color Doppler and high-frequency ultrasound examinations.The diagnostic efficacy of color Doppler and high-frequency ultrasound alone and in combination was analyzed.Results All 68 patients with breast nodules were diagnosed pathologically,showing 52 cases(76.47%)of benign breast nodules and 16 cases(23.53%)of malignant breast nodules.The specificity,sensitivity,and accuracy of the combined detection were 96.15%,93.75%,and 95.59%,respectively,which were higher than those of high-frequency ultrasound(80.77%,75.00%,79.41%)and color Doppler ultrasound(88.46%,81.25%,86.76%).The differences were statistically significant(P<0.05).The irregular morphology,spiky boundary changes,abundant blood flow signals,calcification points in the lesion,uneven echoes,and incomplete capsule of malignant breast nodules were 81.25%,100.00%,87.50%,81.25%,81.25%,and 68.75%,respectively,which were higher than those of benign nodules(50.00%,75.00%,57.69%,51.92%,51.92%,40.38%).The differences were statistically significant(P<0.05).The blood flow grading of benign breast nodules at level 0 and level Ⅰ accounted for 50.00%and 40.38%,respectively,which were higher than those of malignant nodules(0.00%,6.25%).The differences were statistically significant(P<0.05).The proportion of patients with malignant nodules at level Ⅱ and level Ⅲ was 31.25%and 62.50%,respectively,which was higher than that of patients with benign nodules(5.77%,3.85%).The differences were statistically significant(P<0.05).The blood flow resistance index,Vmax,and Vmin of malignant nodules were higher than those of benign nodules.The differences were statistically significant(P<0.05).Conclusion The combined diagnostic identification of benign and malignant breast nodules by color Doppler ultrasound and high-frequency ultrasound is significant and worth applying and promoting.
