V. Khozikov, P. J. Rossman, R. L. Ehman Radiology, Mayo Clinic and Foundation, Rochester, MN, United States Introduction. Dynamic magnetic resonance elastography (MRE) is a method for quantitatively imaging the mechanical properties of tissue, using modified phasecontrast MRI to visualize applied shear waves [1]. There is interest in exploring possible applications of MRE in the diagnosis of br...

Accurate determination of the size or extent of ductal carcinoma in situ (DCIS) by imaging is uncertain, and incomplete resection of tumor results in involved margins in up to 81% of cases. This study examined the accuracy of magnetic resonance imaging (MRI) for assessment of DCIS size, and evaluated the effect of preoperative breast MRI on achievement of tumor-free surgical margins after breas...

Dynamic contrast-enhanced MRI (DCE-MRI) has demonstrated high sensitivity for detection of breast cancer. Analysis of correlation between quantitative DCE-MRI findings and prognostic factors (such as histological tumour grade) is important for defining the role of this technique in the diagnosis of breast cancer as well as the monitoring of neoadjuvant therapies. This paper presents a practical...

The role of pre-operative breast MRI is outlined on the basis of the existing evidence in favor of a superior capability in comparison with mammography and sonography to detect ipsilateral and contralateral malignant lesions and to evaluate the disease extent, including the extensive intraductal component associated with invasive cancers. Patients with a potential higher anticipated benefit fro...

OBJECTIVE The reliability of traditional methods such as physical examination, ultrasonography (US) and mammography is limited in determining the type of treatment response in patients with neoadjuvant chemotherapy (NAC) application for locally advanced breast cancer (LABC). Dynamic contrast-enhanced magnetic resonance imaging (MRI) is gaining popularity in the evaluation of NAC response. This ...

BACKGROUND Preoperative volume assessment is useful in breast reconstruction. Magnetic resonance imaging (MRI) and mammography are commonly available to reconstructive surgeons in the care of a patient with breast cancer. This study aimed to verify the accuracy of breast volume measured by MRI, and to identify any factor affecting the relationship between measured breast volume and actual breas...

Abstract Background Breast cancer is one of the leading causes female morbidity and mortality. Management options vary between lesions BIRADS categories 3 4. Therefore, reliable differentiation would improve outcome. Although sonomammography contrast-enhanced breast magnetic resonance imaging (CE-MRI) remain cornerstone for assessment disease, additional, non-invasive techniques can be used to ...

The objective of this systematic review was to determine the impact of sentinel lymph node (SLN) biopsy and breast magnetic resonance imaging (MRI) on important outcomes for patients with ductal carcinoma in situ. We identified no study that directly evaluated important outcomes for SLN biopsy. So, we determined the incidence of SLN metastases among patients with ductal carcinoma in situ. Using...

BACKGROUND The accurate evaluation of favorable response to neoadjuvant chemotherapy (NCT) is critical to determine the extent of surgery. We investigated independent clinicopathological and radiological predictors to discriminate no residual carcinoma (ypT0) from residual ductal carcinoma in situ (ypTis) in breast cancer patients who received NCT. PATIENTS AND METHODS Parameters of 117 patie...
