This book provides a comprehensive description of the screening and clinical applications of digital breast tomosynthesis (DBT) and offers straightforward, clear guidance on use of the technique. Informative clinical cases are presented to illustrate how to take advantage of DBT in clinical practice. The importance of DBT as a diagnostic tool for both screening and diagnosis is increasing rapidly. DBT improves upon mammography by depicting breast tissue on a video clip made of cross‐sectional images reconstructed in correspondence with their mammographic planes of acquisition. DBT results in markedly reduced summation of overlapping breast tissue and offers the potential to improve mammographic breast cancer surveillance and diagnosis. This book will be an excellent practical teaching guide for beginners and a useful reference for more experienced radiologists.

This superbly illustrated atlas of breast tomosynthesis covers all aspects and applications of the technology, which reduces tissue overlap and facilitates the recognition of small cancers. After clear explanation of basic principles of the technique, individual chapters address diagnostic criteria, indications, and use of breast tomosynthesis as a screening tool. The findings obtained in the full range of benign and malignant conditions, including postoperative changes, are then presented with the aid of a wealth of high-quality illustrations from case examples. Detailed attention is paid to the BI-RADS classification, bearing in mind the ability of tomosynthesis to reduce categorizations as BI-RADS 3 and 0, thereby decreasing the recall rate. The book concludes by examining tomosynthesis-guided interventions such as vacuum-assisted breast biopsy and galactography.

One in eight women in the U.S. will develop breast cancer at some point in their lives. More than half of these cancers are diagnosed at an early stage and the five-year survival rate is 98%. Therefore early detection and diagnosis is paramount. Digital breast tomosynthesis (dBT) (Selenia Di- mensions, Hologic Corporation, Bedford, MA) was approved in February 2011 by the Food and Drug Adminstration (FDA) to be used in combi- nation with mammography for breast cancer screening. With hopes of overcoming the superimposition issues that arise in mammography, DBT acquires 15 projection images over a 15° angular range. The aims of this work were to quantitatively evaluate image resolution as a function of ac- quisition angle and to characterize the radiation dose to the breast for both mammography and tomosynthesis systems.The slice sensitivity profile (SSP) was used to quantitatively measure the image resolution along the z-axis. Using our in-house designed and man- ufactured breast CT (bCT) scanner, which acquires projection images over a 360° angular range, angular ranges between 15° and 360° were studied by using a subset of the projection images acquired on the bCT scanner. As expected it was found that the z-axis image resolution improves as the angular range of acquisition increases. These results provide a quantita- tive understanding of these trends. Patient mammography images were used to evaluate the shape of three breast mimicking phantoms. These phantoms were designed and manu- factured to be modular allowing for an ion chamber/ radiation dose me- ter to be positioned at various x, y and z locations. Employing a high bandwidth ion chamber, the three dimensional dose distribution to the breast was empirically measured for both dBT and mammography. These measured values serve as a validation for computationally modeled data.Lastly, using computational methods dose coefficients (D(gN) ) were devel- oped for contemporary breast imaging systems. In total,eleven reference tables were generated to address systems that are currently deployed or being developed to be used as clinical imaging tools.

Abstract: Purpose: To compare the diagnostic performances of digital breast tomosynthesis (DBT) and ultrasound for the dense breasts with category 0 at conventional digital mammography. Materials and methods: This retrospective study was approved by the institutional review board, and informed consent was waived. Among the 1103 patients who underwent screening digital mammography at our institution, 769 (69.7%) patients had dense breasts. Of the 769 patients, 229 (29.8%) lesions were categorized as 0. DBT, breast ultrasound and digital mammography were performed in 108 (47.2%) patients. BI-RADS final assessments for DBT and ultrasound were recorded. Categories 1–3 were clinically considered as benign, and categories 4 and 5 were clinically considered as malignant. The diagnostic performances of breast ultrasound and DBT were correlated with final pathologic reports or follow-up images. Results: Among 108 lesions, 17 (15.7%) were malignant and 91 (84.3%) were benign. Sensitivity was 100% for both ultrasound (17/17) and DBT (17/17) and negative predictive value was also 100% for both ultrasound (49/49) and DBT (74/74). Specificity and positive predictive value for ultrasound were 53.9% (49/91) and 28.8% (17/59), respectively. Specificity and positive predictive value for DBT were 81.3% (74/91) and 50% (17/34), respectively. DBT showed higher diagnostic accuracy than that of breast ultrasound (DBT: 84.3%, 91/108; ultrasound: 61.1%, 66/108; p

This volume (5116) of Springer’s Lecture Notes in Computer Science contains the th proceedings of the 9 International Workshop on Digital Mammography (IWDM) which was held July 20 – 23, 2008 in Tucson, AZ in the USA. The IWDM meetings traditionally bring together a diverse set of researchers (physicists, mathematicians, computer scientists, engineers), clinicians (radiologists, surgeons) and representatives of industry, who are jointly committed to developing technologies to support clinicians in the early detection and subsequent patient management of breast cancer. The IWDM conference series was initiated at a 1993 meeting of the SPIE Medical Imaging Symposium in San Jose, CA, with subsequent meetings hosted every two years at sites around the world. Previous meetings were held in York, England; Chicago, IL USA; Nijmegen, Netherlands; Toronto, Canada; Bremen, Germany; Durham, NC USA and Manchester, UK. th The 9 IWDM meeting was attended by a very international group of participants, and during the two and one-half days of scientific sessions there were 70 oral presentations, 34 posters and 3 keynote addresses. The three keynote speakers discussed some of the “hot” topics in breast imaging today. Karen Lindfors spoke on “Dedicated Breast CT: Initial Clinical Experiences. ” Elizabeth Rafferty asked the question is “Breast Tomosynthesis: Ready for Prime Time?” Finally, Martin Tornai discussed “3D Multi-Modality Molecular Breast Imaging.

Background Data on the value of digital breast tomosynthesis (DBT) for further assessment of screen-detected lesions are still limited. Purpose To compare screening mammography, single-view DBT and ultrasound-information (TS) vs. screening mammography, additional views and ultrasound-information (AV) for assessment of screen-detected abnormalities. Material and Methods The use of wide-angle DBT for screen-detected, soft-tissue abnormalities requiring additional views was investigated: 241 cases (206 benign and 35 malignant lesions), verified by histology or two-year follow-up, were read by ten readers as TS and as AV sets, yielding 2410 diagnoses for each set. Readings were randomly sequenced. Results The mean interval between readings was nine weeks (random sequence). Evaluation was breast-based. Overall, in terms of area under receiver operating characteristic (AUC; varying degree of suspicion cutoff), TS and AV readings showed similar performance: for TS, AUC was 0.889 (95% confidence interval [CI] = 0.871–0.907) and for AV, AUC was 0.903 (95% CI = 0.886–0.921). TS readings had slightly higher sensitivity than AV readings (96.9% vs. 95.4%) but lower specificity (50% vs. 58.1%) and more variations between reader performance; absolute false negatives (FN) were reduced in 8/16 readers, equal in 5/16, and increased in only 3/16. Conclusion This study broadly confirms previous data showing equivalence of DBT to AV. However, bias against TS may have occurred since the region of interest was not indicated in the TS set as compared to its obvious identification on the AV set by the selected spot views. A key finding is that reader experience with DBT may be more important than so far reported.

The title of this work, Breast Imaging, reflects the intellectual expansion of the field that previously was limited to standard mammography. NMR, Sestimibi scanning, EPR, and optical imaging are all adding to the richness of approaches directed at the early detection of breast cancer. These approaches put us in the enviable position of asking which technologies are the most specific (not just the most sensitive), and which are the most cost effective (and not simply most useful). This book, edited by Dr. Etta Pisano, discusses the key questions and discoveries in breast imaging through a series of timely essays. (We hope that you will enjoy their collective message.)

Digital breast tomosynthesis (DBT), popularly called "3D mammography" is a state-of-the-art breast imaging technology that provides the ability to view inside the breast, layer by layer. Advantages of DBT include elimination of superimposed tissue, improved detection of otherwise hidden lesions, and significantly higher cancer detection rates compared to conventional mammography. Although it is increasingly being implemented in imaging centers, hands-on clinical learning tools have been lacking - until now. Written by renowned breast imaging specialists, this multimedia textbook is the most definitive DBT reference available. The first section is dedicated to DBT fundamentals, including physics, reconstruction methods, acquisition parameters, and patient dose and data size considerations. The next two sections are case-based clinical practice presentations, organized by DBT screening and diagnostic components. Key Features The use of 3D breast imaging to detect and differentiate malignancies from normal and benign findings 100 case studies include pertinent clinical information, introductory images, and findings labeled on subsequent images with BI-RADS terminology Full field digital mammography and/or synthetic 2D mammogram images included in all case studies mirror what is typically encountered in DBT breast-imaging programs Clinical pearls on navigating the technology, interpreting images, making diagnoses, and decisions regarding follow-up studies Accompanying online videos further elucidate the still images This remarkable, interactive reference is a must-have for trainee and practicing radiologists and will also benefit mammography technicians. The detailed case studies and videos demonstrate the full utility of DBT as a screening and diagnostic technology in context with mammography, ultrasound, and MRI of the breast.
