摘　　要：目的:探讨超微血管成像(SMI)下不同大小乳腺癌病灶的血流特征。方法:纳入69例乳腺癌患者(84个病灶),在SMI下观察不同大小(长径≤20 mm、>20 mm)病灶内血管数目及血管形态分布特征。结果:84个病灶中,37个长径≤20 mm,47个长径>20 mm;4个(4.8%)未探及血流信号,25个(29.8%)见1~2条血管,24个(28.6%)见3~4条血管,31个(36.9%)见≥5条血管;54个(64.3%)内部血管粗细不均,59个(70.2%)内部血管扭曲,40个(47.6%)见穿支血管,20个(23.8%)见放射状血管。长径>20 mm的病灶内部多见3~4条或≥5条血管,与长径≤20 mm病灶相比,差异有统计学意义(P<0.05)。长径>20 mm的病灶表现为更多血管粗细不均、扭曲及放射状血管(均P<0.05)。结论:SMI模式下不同大小乳腺癌病灶的血管数目及形态特征存在差异,了解这些特点有助于乳腺癌的诊断。Objective:To investigate the blood flow characteristics of different sizes of breast cancer by superb microvascular imaging(SMI).Methods:Sixty nine patients with breast cancer(84 lesions)were recruited.The number and morphological distribution characteristics of blood vessels in lesions measuring≤20 mm and>20 mm in long diameter were analyzed by SMI.Results:Among the 84 lesions,37 lesions were measured≤20 mm in long diameter,and 47 lesions were measured>20 mm in long diameter.No blood flow signal was detected in 4 lesions(4.8%),1~2 vessels detected in 25 lesions(29.8%),3~4 vessels detected in 24 lesions(28.6%)and≥5 vessels detected in 31 lesions(36.9%).The diameter of blood vessels was uneven in 54 lesions(64.3%),blood vessel distortion was found in 59 lesions(70.2%),perforator vessels in 40 lesions(47.6%)and radial vessels in 20 lesions(23.8%).The proportion of 3~4 vessels,≥5 vessels,the uneven diameter,distorted and radial vessles in lesions measuring>20 mm in long diameter was greater than that in lesions measuring≤20 mm in long diameter(all P<0.05).Conclusions:There are differences of the number and morphological distribution characteristics of blood vessels in breast cancer with different sizes by SMI.The understanding of these characteristics is helpful in the diagnosis of breast cancer.
