Sub-project A (Finished):
1) Women in either BI-RADS 6 situation (i.e. already biopsy proven breast cancer), or women who, based on conventional Imaging, exhibit a lesion
categorized as BIRADS-5 (i.e. a high likelihood of breast cancer) (tested value not older than 8 weeks).
2) Women with normal renal function (MDRD with GFR >= 60 ml/min/1,73m2).
3) Women with normal thyroid function as evidenced by a clinically unobstrusive TSH value.
4) Women who are able to provide informed written consent and are aware of the nature, meaning and extent of the study. 3) Women who provided this written informed consent.
Sub-project B:
1) Same as for sub-project A.
2) Women with non-malignant lesions as defined as being categorized as BI-RADS 4 by conventional imaging-findings.
For sub-project A+B:
1) Women not fulfilling the inclusion criteria.
2) Pregnant or breastfeeding women.
3) Women in child-bearing age without sufficient contraception.
