高频超声对乳腺非结节内微钙化的诊断价值

目的:评价超声对不伴有肿块的乳腺腺体内微钙化的诊断价值,探讨用超声取代钼靶引导定位活检,以发挥超声定位操作简便、易行的优点。方法:选择经乳腺钼靶检查证实的乳腺有微钙化但无明确肿块的患者89例92个病灶,进行超声检查,重点检查钼靶提示有钙化的区域,通过降低增益、局部放大、多切面检查,以提高检出率。对病灶进行术前超声引导带钩钢丝定位活检。结果:有69个微钙化灶被超声检出,超声对乳腺微钙化灶的检出率为75%(69/92)。65个微钙化分布在低回声背景内,其中38个呈簇状分布,27个沿导管分布;另外4个局部腺体无明显改变,其中3个呈簇状分布、1个沿导管分布。经术后病理证实,14个为良性,超声检出率20.3%个(14/69);55个为恶性,超声检出率79.7%(55/69)。结论:超声检查能显示乳腺腺体内无软组织结节的微钙化灶,有低回声背景的微钙化更容易显示。对恶性微钙化的检出率明显高于良性,二者的差异有统计学意义(P0.05)。

The diagnostic value of high frequency ultrasound to mammary gland intra-non-bump microcalcification

Objective:To evaluate the ultrasonic diagnostic value for mammary gland intra-non-bump microcalcification and to explore the possibility using ultrasound to replace molybdenum target directed localized biopsy so as to exert the the advantages of ultrasound in terms of easy localization,dynamical observation,no radiation damage,and low cost.Methods:89 patients with 99 foci were subjected to mammary gland molybdenum target examination,which showed that mammary gland had doubtful microcalcification but no defi...
