回复：Breast Ultrasound vs Mammogram

是的，我也想问是否可以先做Ultrasound.

我朋友是very dense 的情况，在个两国家都做过检查，国内follow 手检ultrasound 发现的 nodule ,国外直接mammo没发现。


我读到的一些资料，例如:
How does a woman know if her breasts are dense or extremely dense?

“It’s a “Catch- 22”,” said co-author Diana L. Miglioretti, PhD, a senior investigator at Group Health Research Institute who is also at the University of California at Davis. “The only standard way to determine your level of breast density is to get a mammogram. But unless your breasts are extremely dense and you have other strong risk factors, the data don’t necessarily support your starting screening mammograms before age 50.”

但是这些文献在提出这个问题的同时，并没有提到先做ultrasound （screening）作为一个alternative。我知道这里有筛选和诊断的区别。如果能有选择就好了。
