Pulses are transmitted into anatomically realistic MRI-derived numerical breast phantoms with different levels of tissue heterogeneity as well as foreign entities such as implants and surgical clips, and the specific absorption is computed. 漏 2006 Wiley Periodicals, Inc.

Surgical clips are recommended for accurate tumour bed localization [70,71], although this has not been uniformly adopted. In this regard, magnetic resonance imaging (MRI) may represent an additional tool to increase tumour bed localization, as compared to CT. Conflicting results reported by ...
Scattered clips (in 43 -73% of patients undergoing surgery, clips on postoperative CT imaging were visualized outside the original quadrant of the tumor) [45, 46]. Preoperative tumor delineation on CT scans leads to less inter-observer variability compared to postoperative delineation of tumor bed...
In addition, the development of ultrasound-visible clips has allowed breast surgeons to perform ultrasound guided excisions without the need for preoperative localization.20 The clips, which are placed at the time of initial biopsy, obviate the need for pre-operative localization procedures. Several ...
4.2 Contraindications for breast MRI examinations (1) Pregnancy. (2) Ferromagnetic materials such as pacemakers and surgical metal clips in their bodies, and other materials, prohibit them from approaching a strong magnetic field. (3) Claustrophobia. (4) History of allergy to any MRI contrast ...
Localisation of the clipped nodes with wire placement should also be studied under computed tomography (CT)-guidance in addition to US guidance to improve the detection rates of the clips, as validated previously [27, 28]. The primary aim of this study was to evaluate the feasibility of ...

6 cases (for calcification/clips) used DBT-biopsy at users discretion. In 45 cases, the DBT-biopsy was benign. Conclusion: DBT-biopsy is a useful tool in the assessment of breast disease. It is particularly helpful in assessment of subtle distortions which were ultrasound occult, and where ...
Other common normal findings within a reconstructed breast include the presence of a vascular pedicle and/or surgical clips [8], [9], [10]. The normal mammographic features of a TRAM flap are shown in Figure 4, and Figure 5 shows the normal mammographic and MRI features of a DIEP flap....
Locally advanced breast (LABC) consists of inflammatory breast cancer (IBC) and non-IBC locally advanced breast cancer (non-IBC LABC).Although the diagnostic work-ups and management are similar, there are subtle differences in terms of biology and surgical management. Some of the topics in this...
