Book excerpt: Purpose: The purpose of our study is to review the state of the art in nuclear medicine imaging of the breast (scintimammography) and to evaluate a novel, high-resolution, breast-specific gamma camera (HRBGC) for the detection of suspicious breast lesions. Materials and Methods: Fifty patients with 58 breast lesions in whom a scintimammogram was clinically indicated were prospectively evaluated with a general-purpose gamma camera and a HRBGC prototype. Nuclear studies were prospectively classified as negative (normal/benign) or positive (suspicious/malignant) by two radiologists, blinded to mammographic and histologic results with both the conventional and high-resolution. All lesions were confirmed by pathology. Results: Included in this study were 30 benign and 28 malignant lesions. The sensitivity for detection of breast cancer was 64.3% (18/28) with the conventional camera and 78.6% (22/28) with the HRBGC. Specificity of both systems was 93.3% (28/30). In the 18 nonpalpable cancers, sensitivity was 55.5% (10/18) and 72.2% (13/18) with the general-purpose camera and HRBGC, respectively. In cancers? 1cm, 7 of 15 were detected with the general-purpose camera and 10 of 15 with the HRBGC. Four of the cancers (median size, 8.5 mm) detected with the HRBGC were missed by the conventional camera Conclusion: Evaluation of indeterminate breasts lesions with a high resolution, breast-specific gamma camera results in improved sensitivity for the detection of cancer with greater improvement demonstrated in nonpalpable and?1 cm cancers.

Download or read book Evaluation of Optical Sonography Trademark for Real Time Breast Imaging and Biopsy Guidance written by George F. Garlick and published by . This book was released on 2001 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there have been recent advances in the development of complementary approaches to breast mammography, breast cancer remains a prevalent and devastating disease. For the most part new advances fail to provide real-time, large field of view, high-resolution approaches to breast imaging where both early detection and subsequent management of breast disease are primary targets. The purpose of this three-year study is to evaluate a promising approach to breast imaging using a diffractive energy imaging technology developed by Advanced Diagnostics, Inc. Progress in the first year lead to methods for evaluating the changes to a prototype system and collecting breast imaging data. This report describes progress made during the second year of the study to implement these methods. Reliable and repeatable procedures for quantifying system performance and collecting breast imaging data will be discussed. The results of data collected from a group of individuals with normal breast anatomy, along with preliminary results from simulated breast biopsies will also be presented. These results continue to provide valuable information to the ADI's image quality improvement program and have had a positive impact on system development.

Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasing number of digital mammograms and the advent of new kinds of three-dimensional x-ray and other forms of medical imaging, mammography is undergoing a dramatic change. To meet their responsibilities, medical physicists must constantly renew their knowledge of advances in medical imaging or radiation therapy, and must be prepared to function at the intersection of these two fields. Physics of Mammographic Imaging gives an overview on the current role and future potential of new alternatives to mammography in the context of clinical need, complementary approaches, and ongoing research. This book provides comprehensive coverage on the fundamentals of image formation, image interpretation, analysis, and modeling. It discusses the use of mammographic imaging in the detection, diagnosis, treatment planning, and monitoring of breast cancer. Expert authors give a balanced summary of core topics such as digital mammography, contrast-enhanced mammography, stereomammography, breast tomosynthesis, and breast CT. The book highlights the use of mammographic imaging with complementary breast imaging modalities such as ultrasound, MRI, and nuclear medicine techniques. It discusses critical issues such as computer-aided diagnosis, perception, and quality assurance. This is an exciting time in the development of medical imaging, with many new technologies poised to make a substantial impact on breast cancer care. This book will help researchers and students get up to speed on crucial developments and contribute to future advances in the field.
Download or read book Mammography and Beyond written by National Research Council and published by National Academies Press. This book was released on 2001-07-23 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year more than 180,000 new cases of breast cancer are diagnosed in women in the U.S. If cancer is detected when small and local, treatment options are less dangerous, intrusive, and costly-and more likely to lead to a cure. Yet those simple facts belie the complexity of developing and disseminating acceptable techniques for breast cancer diagnosis. Even the most exciting new technologies remain clouded with uncertainty. Mammography and Beyond provides a comprehensive and up-to-date perspective on the state of breast cancer screening and diagnosis and recommends steps for developing the most reliable breast cancer detection methods possible. This book reviews the dramatic expansion of breast cancer awareness and screening, examining the capabilities and limitations of current and emerging technologies for breast cancer detection and their effectiveness at actually reducing deaths. The committee discusses issues including national policy toward breast cancer detection, roles of public and private agencies, problems in determining the success of a technique, availability of detection methods to specific populations of women, women's experience during the detection process, cost-benefit analyses, and more. Examining current practices and specifying research and other needs, Mammography and Beyond will be an indispensable resource to policy makers, public health officials, medical practitioners, researchers, women's health advocates, and concerned women and their families.

Available in PDF, EPUB and Kindle. Book excerpt: A small field of view gamma camera based on a Position Sensitive Photomultiplier Tube has been used for tomoscintigraphic imaging of breast phantoms. The breast phantoms consist of small hot quantities of 99mTc placed in a plastic pot filled with a lower concentration 99mTc solution. The volume of the hot quantities varied from 0.5 to 0.25 ml and the target to background activity ratio varied from 3:1 to 5:1. The impact of the acquisition time per projection and the number of projections on image quality has been investigated.

Download or read book Dual Modality Imaging System for Breast Cancer Research written by and published by . This book was released on 2004 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 25-40% of the general female population with radiodense breast parenchyma, clinically occult lesions may be invisible in the screen-film mammogram. Even if suspicious masses are detected, determination of the benign or malignant nature of a mass is often impossible from the x-ray image. There is thus a need for diagnostic procedures that can noninvasively help characterize suspicious breast lesions. Scintimammography is an imaging technique that shows promise as an adjunct diagnostic tool in problem solving mammography, for monitoring recurrence after surgery, and in the assessment of multidrug-resistance. However, because clinical Anger cameras have only moderate spatial resolution and are difficult to position close to the breast, small lesions are difficult to detect. In addition, no direct means exists of correlating mammographic and scintigraphic information because of the significantly different shape of the breast in mammography (compressed) and scintimammography (prone, pendulant). We are developing an imaging system that overcomes these problems by combining digital x-ray mammography and gamma emission scintigraphy in a single, integrated system. The system is mounted on a standard upright mammography unit, and can easily be placed in a typical mammography room, providing accessibility even for small breast imaging clinics not associated with major medical centers.
