MRI,meanwhile,is proving to be a promising adjunct to the imperfect art of mammography."Whereas ordinary mammography looks at calcium deposits and masses,MRI looks at blood vessels," explains Larry Norton,MD,deputy physician-in-chief for breast cancer programs at Memorial Sloan-Kettering Cancer Center in New York City."All cancers have abnormal blood vessels."
Another potential alternative to mammography,which would not require radiation,is also under investigation.Called optical imaging,this technique would allow doctors to create images of the abnormal blood vessels in a tumor by passing light rays through breast tissue.

另外,核磁共振成像也有望成为尚不成熟的早期胸部肿瘤X射线透视法的补充手段.“一般的X射线透视法可以检查出钙的沉积和成块迹象,而MRI可以检查出血管的异常.”纽约的纪念斯隆-凯特琳癌症中心的胸部肿瘤主治医生的代表,拉里·诺顿医生解释说,“所有的癌症都有血管异常症状.”
另一种可能替代早期胸部肿瘤X射线透视法的检查方法也正在研究中,这就是无辐射的光学造影技术,即医生利用特定光线照射胸部组织,得到肿瘤中的不规则血管成像.
纪念斯隆-凯特琳癌症中心是美国最著名的癌症研究中心之一.
