I. Overview Dynamic Contrast Enhanced MRI (DCE-MRI) is a rapidly evolving imaging technique, and it is widely applicable in management of various cancers. It is the current standard for breast MR imaging; also many research studies have been conducted to evaluate its application for other cancers. This tutorial is focused on the analysis of DCE-MRI data, and how the analyzed parameters are used...

OBJECTIVES This systematic review aimed to assess the role of magnetic resonance imaging (MRI) in evaluating residual disease extent and the ability to detect pathologic complete response (pCR) after neoadjuvant chemotherapy for invasive breast cancer. METHODS PubMed, the Cochrane Library, MEDLINE, and Embase databases were searched for relevant studies published until 1 July 2012. After prim...

Contemporary radiotherapy (RT) planning utilizes both a computed tomography (CT) scan either in prone or supine position with no breast compression or magnetic resonance imaging (MRI). The application of MRI is limited by image distortion and a lack of electron density information. The standard supine position not only exposes the tumor to RT non-homogenously, it can cause damage to the neighbo...

New evidence on breast Magnetic Resonance Imaging (MRI) screening has become available since the American Cancer Society (ACS) last issued guidelines for the early detection of breast cancer in 2003. A guideline panel has reviewed this evidence and developed new recommendations for women at different defined levels of risk. Screening MRI is recommended for women with an approximately 20-25% or ...

OBJECTIVE To determine whether preoperative breast MRI is more useful in patients according to their breast density, age, menopausal status, and biopsy findings of carcinoma in situ. MATERIAL AND METHODS We retrospectively studied 264 patients treated for breast cancer who had undergone mammography, ultrasonography, and MRI. We compared the size of the tumor on the three techniques and the se...

Breast Specific Gamma Imaging (BSGI) is scintimammography performed with breast optimized detectors and has been found to be a cost-effective, highly sensitive and specific breast imaging procedure. Therefore, several authors have proposed various applications for this modality as an adjunctive procedure to mammography and other applications (1,2). The purpose of this summary is to propose the ...

Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is being increasingly used in the clinic as an adjunct to x-ray mammography and ultrasound for the detection and characterisation of breast cancer. The technique involves acquiring T1-weighted volume images of one or both breasts before and at several time points after the injection of a contrast agent. Interpretation of this 4D dat...

Introduction Conventional mammography is known to have high false positive rate (60-80%) in detection of breast malignancy, resulting in unnecessary biopsies. Recently, dynamic contrast enhanced (DCE) MRI demonstrated high sensitivity (88-100%), but rather limited and variable specificity (37-97%) in diagnosis of breast cancer (1). In vivo H MRS showed excellent specificity in detection of mali...

Breast capillary hemangioma is a type of benign vascular tumor which is rarely seen. Little is known about its presentation on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Here, we describe a case of suspicious breast lesion detected by DCE-MRI and pathologically confirmed as capillary hemangioma. Our case indicates that a small mass with a superficial location, clear boundar...

Breast imaging represents a relatively recent and promising field of application of quantitative diffusion-MRI techniques. In view of the importance of guaranteeing and assessing its reliability in clinical as well as research settings, the aim of this study was to specifically characterize how the main MR scanner system-related factors affect quantitative measurements in diffusion-MRI of the b...
