摘要
目的：研究正常成年女性静止期乳腺实质的超声表现，并对其进行分型。方法：自2005年5月至2006年6月在乳腺普查中，使用高频超声对4392例成年女性静止期乳腺进行超声检查，根据超声图像中显示的乳腺导管数量与问质等其他成分比例的不同，将乳腺实质的超声表现分为四型：①导管占主要成分者为导管型；②纤维结缔组织占主要成分者为致密型；③导管与纤维结缔组织比例相当者为混合型；④除导管和纤维结缔组织外，脂肪等其他成分所占比例较多者为不均型。结果：4392例成年女性静止期乳腺中，双侧乳腺均为导管型者360例（8．20%），致密型1373例（31．26％），混合型2356例（53．64％），不均型113例（2．57％）。尚有119例（2．71％）双侧乳腺分别为不同类型。在年龄分布上，导管型主要分布在18～20岁和21～30岁两个年龄段（21．55％～42．86%），在61～70岁年龄段仅有1例，在71～80岁和81～90岁两个年龄段均无导管型。50岁以下受检女性主要为混合型（54．61%～61．64％）。随年龄增长，致密型比例逐渐增高，致密型在51～60岁组为43．01％，61～70岁组为65．27％，71～80岁组为72．46％。不均型在各个年龄段的分布无明显差异（1．94％～4．19％）。结论：正常成年女性静止期乳腺实质超声可分为导管型、混合型、致密型和不均型四型。导管型主要见于青年女性，中年女性主要为混合型和致密型，老年女性以致密型为主。不均型在各个年龄段的分布无明显差异。少数人双侧乳腺类型不相同。
Objective To illustrate ultrasound types of normal resting stage breast in adult Chinese females using high-resolution sonography. Methods In breast screening programme,4392 normal resting stage breast in adult Chinese females had been examined with high-resolution ultrasound between May 2005 and July 2006. The sonographic patterns were classified according to proportion of glandular duct,fibrous and fatty of bresat contents into four categories. It was duct type with rich breast ducts. The fibrous were mainly components in density type. The proportion of duct and fibrous might be represented quits in mixture type. The breast image was not homogeneous with a fibroglandular and fatty structure being inhomogenous type. Classification results obtained by the stablly two sonographic doctors. Results Four thousand three hundred and ninty-two normal breast pairs were divided into 4 groups. Classification included 8. 20% with duct type, 31.26% with density type, 53.64% with mixture type,2.57% with inhomogenous type. Duct type were mainly existed in 18-20 and 21-30 years of age. There were not duct type in over 71 years of age,only one was in 61-70 years of age. There were mainly mixture （54. 61%- 61.64%） under 50 years of age. The proportion of density was higher follow age growth,43.01% density in 51-60 years of age,65.27 % density in 61-70 years of age and 72. 46% density in 71-80 years of age. The proportion of inhomogenous was no differences in any age. In 2. 71% different type of same woman breast of 4392 normal breast pairs were found. Conclusions There are four sonographic types with normal resting stage breast in adult Chinese females. Mixture and density are main types. By comparison,duct and inhomogenous are little. There are mainly duct in the young,mixture and density in middle-aged and density in old age. No differences in any age inhomogenous are dispersed. And few women show different type of breast.
