Findings:  The breast tissue is heterogeneously dense. No suspicious findings are present. No significant change from the study two years earlier. Right breast ultrasound shows irregular, hypoechoic masses measuring approximately 5 x cm in the right breast with marked posterior acoustic shadowing. These were not significantly changed from an ultrasound performed two years earlier. 结论:胸部异常密度,未有可疑发现。较两年前发现时未有明显。右乳超声示约5 x cm不规则低密度肿块影,后方伴声影,较两年前超声检查无明显改变。
