Des...

Tumor-related vessel length (TVE) was quantified as the number of pixels skeletonized tumor vessels on ultrafast dynamic contrast-enhanced MRI (UF-DCE MRI). The association between TVE and breast cancer subtypes investigated. Invasive presenting with human epidermal growth factor receptor 2 (HER2) associated increased tumor-related length.

ma. It accounts for less than 5% of breast cancers (1-3), and it may have a poorer prognosis than most other breast malignancies (4, 5). Some authors have reported a metaplastic carcinoma of the breast with the mammographic and sonographic features (3, 6), however, typical magnetic resonance imaging (MRI) findings are unknown. The MRI findings of a metaplastic carcinoma of the breast were evalu...

PURPOSE To determine the frequency by which breast magnetic resonance imaging (MRI) provides information that influences the surgical management of patients with breast cancer. MATERIALS AND METHODS From August 2006 to December 2008, contrast-enhanced bilateral breast MRI was performed on 68 patients, all of whom exhibited highly suspicious imaging findings (BI-RADS category 4 or 5). Patients...

BACKGROUND Clinical scores of mammographic breast density are highly subjective. Automated technologies for mammography exist to quantify breast density objectively, but the technique that most accurately measures the quantity of breast fibroglandular tissue is not known. PURPOSE To compare the agreement of three automated mammographic techniques for measuring volumetric breast density with a...

Radiol Bras. 2017 Mar/Abr;50(2):VII–VIII Despite the undeniable success of mammography in the detection of breast cancer, the method has major limitations, one of which is that it is difficult to detect malignant lesions by mammography, because of the high density of the fibroglandular parenchyma. Another significant limitation is the potential for false-negative results. It has been shown that...

The use of a breast magnetic resonance imaging (MRI) in the evaluation of cancer is increasing. The absolute contraindications for MRI are well known. Lesser know are the thermal injuries or burns caused by MRI. During a recent breast MRI of a patient with an ulcerated locally advanced breast cancer we did a remarkable observation. Almost directly from the start of the MRI the patient felt a sl...

1596 Background: Magnetic resonance imaging (MRI) is the preferred imaging modality for screening and diagnosis of breast cancer in BRCA-1and BRCA-2 mutation carriers. However, there is limited data on the radiographic features of BRCA1/2-positive breast cancers on MRI. This study evaluates the MRI characteristics of BRCA1/2 -related breast cancers. METHODS All female BRCA mutation carriers w...

PURPOSE To assess the diagnostic accuracy of mammography, ultrasound, and magnetic resonance imaging (MRI) of the breast in the surveillance of women at high risk for breast cancer. EXPERIMENTAL DESIGN In this prospective comparison study, women at high risk for breast cancer were offered annual surveillance examinations, consisting of mammography, ultrasound, and MRI, at a single tertiary ca...

Abstract Background Unilateral primary breast edema may pose a diagnostic challenge. Excluding malignant etiologies is of utmost importance and require the use dynamic MRI examination as problem solver. Yet, enhancement pattern benign disorders associated with edematous breasts overlap, this add to dilemma. So, our aim in current study was assess role T2-weighted MR imaging problem-solving sequ...
