| Objective:To explore the application value of high frequency ultrasound in benign and malignant small breast nodules
and its ultrasonic manifestations.Methods:184 cases of patients diagnosed small breast nodules in our hospital were selected. Before operation,
these nodules were detected using high frequency ultrasound technology, which were compared with postoperative pathological
detection results. The morphology, blood flow, microcalcification and outline of nodules between benign nodules and malignant nodules
was also analyzed and compared.Results:By high-frequency ultrasound, 238 small nodules were detected in the 184 patients with breast
small nodules, including 194 benign nodules and 44 malignant nodules; Pathological section showed 244 small nodules, of which 197 benign
nodules and 47 malignant nodules. Compared with the pathological slice, high-frequency ultrasound nodule detection rate was as
high as 97.5 %, benign and malignant nodules detection accuracy rate were 98.5 %, 98.5%; Nodules form rule contrast, benign nodules
more rules than malignant nodules, calcified situation is, not all nodules of calcification, no comparability between calcification is; Nodal
brim contour sharpness, benign nodules showed more edge was clear, and malignant tumor more cash for edge blur, nodal brim benign
nodules more clear than malignant nodules; for the detection of blood flow, malignant nodules group was significantly higher than that of
benign nodules group.Conclusion:High frequency ultrasound detection rate of small breast nodules is higher with low error rate, is the
important way to identify small nodules of benign and malignant breast, has higher application value and plays an important role for the
early diagnosis of breast cancer. |
