| 目的 探讨非乳腺手术术后乳腺实质超声分型,分析其与年龄的相关性及其在常见乳腺病变筛查中的应用价值。方法 选取我院进行超声检查的非乳腺手术术后患者200例(400侧乳腺),进行乳腺超声图像进行分型研究；根据受检者超声图像下乳腺实质的结构表现进行分型,分别为腺体型、腺纤维Ⅰ型、腺纤维Ⅱ型和脂肪型；并分析分型人群与各年龄段的相关性。结果 受检者中腺体型检出率与年龄增长成反比(r=-0.534)；脂肪型检出率与年龄增长成正比(r=0.116)；50岁前腺纤维Ⅰ型乳腺检出率多且相对稳定,而50岁后其检出率下降；腺纤维Ⅱ型乳腺检出率在60岁以下与年龄增长成正比,50～59岁年龄段检出率达到峰值,60岁以后检出率下降。超声各分型的检出率与年龄间差异有统计学意义(P＜0.05)。结论 非乳腺手术术后妇女乳腺超声分型与受检者年龄密切相关；终末导管小叶单元的退化速度比年龄的增长速度快这一现象应视为乳腺疾病重点筛选条件。 |

| ABSTRACT Objective To explore the correlation between the breast parenchyma ultrasound and the age and the application value in the screening of common breast lesions. Methods A total of 400 breast disease in 200patients were investigated by ultrasound. The ultrasonic image patterns were classified according to the tissue structure and involution of breast into glandular，fibro glandular，fibro glandular Type Ⅱ and fatty types. Results The detection rate of the gland body type was in inverse proportion to the age of the subjects (r=-0.534). The rate of fatty type was directly proportional to the age of the patients (r=0.116). Before 50 years of age，the proportion of fibro glandular type Ⅰ was stabilized decreased after 50 years of age. Before 60 years of age，the proportion of fibro glandular Type Ⅱ increased along with an increase of ages with a peak value in groups of 50-59 years，but decreased after 60 years. There was significant difference of the proportion in any age，P＜0.05. Conclusion The age of breast ultrasound classification and the age of the patients were closely related with the age of the patients after non breast surgery, and the rate of degeneration of the terminal duct was faster than that of the age, what should be regarded as the focus of breast disease screening conditions. |
