ConclusionsUS may underestimate breast tumor size. Treatment decisions that take into account tumor size can be made equally reliably in patients with high or low breast density.

Astley, D.Gareth EvansAbstractThe incidence of breast cancer continues to increase worldwide. Population-based screening is available in many countries but may not be the most efficient use of resources, thus interest in risk-based/stratified screening has grown significantly in recent years. An important part of risk-based screening is the incorporation of mammographic density (MD) and single nucleotide polymorphisms (SNPs) into risk prediction models to be comb...

The objective of this study was to evaluate the diagnostic performance of magnetic resonance imaging (MRI) in detecting the secondary breast cancer among women with a personal history of the lesion. Materials and Methods We retrospectively reviewed breast MRI examinations performed between 2007 and 2011. A total of 798 women with a history of breast cancer were included in the study. Cancer detection rate, positive predictive value (PPV), recall rate, sensitivity, and specificity were assed. Cancer detection rate was stratified by interval after surgery of the primary breast cancer. Also, we derived 1 comparison group f...

Abstract The detection of lymph node metastasis affects the management of patients with primary breast cancer significantly in terms of staging, treatment, and prognosis. The main goal for the radiologist is to determine and detect the presence of metastatic disease in nonpalpable axillary lymph nodes with a positive predictive value that is high enough to initially select patients for upfront axillary lymph node dissection. Features that are suggestive of axillary adenopathy may be seen with different imaging modalities, but ultrasound is the method of choice for evaluating axillary lymph nodes and for performing...

You’re staring at a letter from your mammography facility. Your breast exam was normal, great. But then you see a note on the bottom: you have high breast density, which could put you at higher risk for breast cancer in the future. Now what? “The finding of dense breasts on a mammogram can be stressful and confusing for patients,” says Dr. Toni Golen, acting editor in chief of Harvard Women’s Health Watch. It’s information that may concern them, but they don’t know what to do about it. What is breast density? Breasts are composed of: lobules, which produce milk ducts, tubes that carry m...

To study the imaging and clinical features of breast sclerosing adenosis (SA), and to enhance the recognition of this disease, as well as to help the clinic to give a correct diagnosis. Imaging findings were retrospectively reviewed in 47 women with SA lesions confirmed by pathology (including 39 cases of mammography, 40 cases of ultrasound [US], and 34 cases magnetic resonance imaging [MRI]). Of 47 patients confirmed with SA, 18 cases were pure SA, and 29 cases coexist with other proliferative lesions and malignancies; the maximum diameter of SA lesions was 0.5 to 3.5 cm with an average of 1.6 cm. On the mammogram o...

ConclusionsMRI is the best predictor of tumor size in breast cancer. Histologic type and tumor size are key parameters when estimating tumor size and should be taken into account when planning surgery. Patient age does not interfere with the interpretation of imaging tests.ResumenIntroducciónEl objetivo de este estudio fue evaluar qué prueba de imagen de las empleadas para medir el tamaño del cáncer de mama primario preoperatorio (mamografía, ecografía o resonancia magnética (RM)) se correlacionó mejor con el tamaño del tumor en la pieza quirúrgica posto...

Introduction: We investigated the downstream workup and costs associated with digital breast tomosynthesis (DBT) compared with 2-dimensional full field digital mammogram (FFDM) when employed as initial follow-up imaging in breast conservation therapy. Methods: Between the years 2015 and 2017, 450 consecutive breast conservation therapy patients, ages 32 to 89, with a follow-up DBT (n=162) or FFDM (n=288) were retrospectively reviewed. The primary endpoints were further workup after follow-up mammogram and associated health care costs at 1 year. A single DBT costs an estimated $149 compared with $111 for FFDM, based on...

AbstractPurposeTo develop a multiparametric [18F]FDG positron emission tomography/magnetic resonance imaging (PET/MRI) model for breast cancer diagnosis incorporating imaging biomarkers of breast tumors and contralateral healthy breast tissue.MethodsIn this prospective study and retrospective data analysis, 141 patients (mean 57  years) with an imaging abnormality detected on mammography and/or ultrasound (BI-RADS 4/5) underwent combined multiparametric [18F]FDG PET/MRI with PET/computed tomography and multiparametric MRI of the breast at 3  T. Images were evaluated and the following were recorded: for the tumor,...
