The latest edition of the Breast Imaging Reporting and Data Systems lexicon, copyrighted in 2013, contains several changes to the breast MR imaging section. Most changes were implemented to standardize descriptors across breast imaging modalities. New sections on special topics and implant evaluation are included. We review basic MR imaging breast anatomy and a detailed pictorial review of the Breast Imaging Reporting and Data Systems lexicon, including these new sections. In each section we discuss which descriptors are more concerning for malignancy and information radiologists can use to better categorize findings as lower risk or benign...

Dynamic contrast-enhanced MRI is the workhorse of breast MRI, where the diagnosis of lesions is largely based on the enhancement curve shape. However, this curve shape is biased by RF transmit (B1 + ) field inhomogeneities. B1 + field information is required in order to correct these. The use of a generic, coil-specific B1 + template is proposed and tested. Finite-difference time-domain simulations for B1 + were performed for healthy female volunteers with a wide range of breast anatomies. A generic B1 + template was constructed by averaging simulations based on four volunteers...

BACKGROUND: Augmented reality (AR) enables the superimposition of virtual reality reconstructions onto clinical images of a real patient, in real time. This allows visualization of internal structures through overlying tissues, thereby providing a virtual transparency vision of surgical anatomy. AR has been applied to neurosurgery, which utilizes a relatively fixed space, frames, and bony references; the application of AR facilitates the relationship between virtual and real data. Augmented Breast imaging (ABI) is described...

Optimizing preoperative planning is widely sought in deep inferior epigastric artery perforator (DIEP) flap surgery. One reason for this is that rates of fat necrosis remain relatively high (up to 35%), and that adjusting flap design by an improved understanding of individual perforasomes and perfusion characteristics may be useful in reducing the risk of fat necrosis. Imaging techniques have substantially improved over the past decade, and with recent advances in 3D printing, an improved demonstration of imaged anatomy has become available...

REVIEW
Yuanxin Liang, Stephen P Naber, Abhishek Chatterjee
Oncoplastic surgery provides breast cancer patients with greater aesthetic satisfaction without compromising disease-free survival or overall survival rate. Large volume displacement oncoplastic surgical techniques have become increasingly popular as a strategy for improving aesthetic outcomes and extending the option of breast conservation therapy. They often involve breast reduction or mastopexy reconstructive techniques to facilitate resection of large breast volumes on the side of the breast cancer and accompanied with symmetry contralateral breast reductions or mastopexies...

Unlike physicians, veterinary practitioners must deal with a number of animal species with crucial differences in anatomy, physiology and metabolism. Accordingly, the pharmacokinetic behaviour, the clinical efficacy and the adverse or toxic effects of drugs may differ across domestic animals. Moreover, the use of drugs in food-producing species may impose a risk for humans due to the generation of chemical residues in edible products, a major concern for public health and consumer's safety. As is clearly known in human beings, the ATP binding cassette (ABC) of transport proteins may influence the bioavailability and elimination of numerous drugs and other xenobiotics in domestic animals as well...

OBJECTIVES AND RATIONALE: Radiology-pathology correlation is time-consuming and is not feasible in most clinical settings, with the notable exception of breast imaging. The purpose of this study was to determine if an automated radiology-pathology report pairing system could accurately match radiology and pathology reports, thus creating a feedback loop allowing for more frequent and timely radiology-pathology correlation. METHODS: An experienced radiologist created a matching matrix of radiology and pathology reports...

Significant technologic advances in radiation treatment delivery now allow for more personalized delivery considerations which incorporate individual patient characteristics (such as tumor location and patient anatomy) and more precise delivery in the breast conservation or post-mastectomy setting. The combined advancements with other treatment modalities (i.e., systemic therapy, surgical management) have had direct effects on local-regional management and outcomes such that currently, local-regional relapses after definitive treatment for localized disease are now rarely experienced...

Molecular breast imaging (MBI), also called breast-specific gamma imaging (BSGI), has been an integral component of our breast imaging practice for over a decade. Unlike mammography and ultrasound that are based on anatomy, MBI is a physiologic approach to breast cancer detection. MBI detects additional foci of occult breast cancer in 9.0% of women with newly diagnosed breast cancer, has a high sensitivity for detecting high-risk lesions, and detects 98% of invasive breast cancer and 91.0% of ductal carcinoma in situ...

Breastmilk is the physiologic norm for infant nutrition. Despite recommendations from major health organizations, many women in the U.S. are not achieving this metric. Understanding breast anatomy and lactation physiology will allow physicians to gain knowledge of the processes, which control lactation enabling physicians to appropriately manage the breastfeeding dyad. The interplay of hormones involved in lactation and milk management affect milk initiation, as well as ongoing milk production (galactopoesis)...

We present a case of intraventricular meningioma resected via a transcortical approach using tractography for optic radiation and arcuate fasciculus preservation. We include a review of the literature. A 54-year-old woman with a history of breast cancer presented with gait imbalance. Workup revealed a mass in the atrium of the left lateral ventricle consistent with a meningioma. Whole brain automated diffusion tensor imaging (DTI) was used to plan a transcortical resection while sparing the optic radiations and arcuate fasciculus...

Breast cancer staging concisely summarizes disease status, creating a framework for assessing and relaying prognostic information. The fundamental concepts and components of breast cancer staging are reviewed. The AJCC Cancer Staging Manual, which includes traditional anatomic factors, now includes additional tumor characteristics: tumor grade, estrogen receptor status, progesterone receptor status, human epidermal growth factor receptor 2 status, and (when available) multigene panel testing from the primary tumor...

Patients with breast cancer are surviving longer as the state of the art for care advances. Because patients are surviving longer with primary breast cancer, the incidence of secondary metastatic disease has risen. Metastatic breast cancer to the brain was once thought to be universally fatal. While it is still quite lethal, its treatment after diagnosis is increasingly safe and effective. Critical progress has been made in understanding the interaction between breast metastases and the neural niche, neuroimaging of functional anatomy, minimally invasive image-guided brain surgery, characterizing subtypes of breast cancer based on molecular and genetic profiles, and individualized pharmaceuticals and immunotherapies...
