  • Digital Mammography / IWDM - A harmonized quality control program for Digital Mammography
    Digital Mammography, 2006
    Co-Authors: Martin J. Yaffe, Gordon E. Mawdsley, Aili K. Bloomquist
    Abstract:

    Digital Mammography is rapidly becoming a mature imaging modality. To maintain high quality in Mammography, a routine quality control program is necessary to detect drifting or degradation of system performance over time. The American College of Radiology is developing a quality control program which will apply to all types of full-field Digital Mammography equipment, and provide effective and more efficient validation of performance. In the DMIST trial, there were no failures for many of the QC tests during the 24 months imaging was performed. When systems failed, they generally did so suddenly, rather than through gradual deterioration of performance. A recommended set of tests is presented, which can be used to ensure that full-field Digital Mammography (FFDM) systems are functioning correctly, and consistently producing mammograms of excellent image quality.

  • contrast enhanced Digital Mammography initial clinical experience
    Radiology, 2003
    Co-Authors: Roberta A Jong, Mia Skarpathiotakis, Nathalie M Danjoux, Anoma Gunesekara, Martin J. Yaffe, Rene Shumak, Donald B. Plewes
    Abstract:

    PURPOSE: To investigate the potential of using intravenous contrast material with full-field Digital Mammography to facilitate the detection and characterization of lesions in the breast. MATERIALS AND METHODS: Twenty-two women scheduled for biopsy because they were suspected of having abnormalities at breast imaging underwent imaging with contrast material–enhanced Digital Mammography. Six sequential images of the affected breast were obtained, with a contrast agent injected intravenously between the time the first and second images were obtained. Image processing included registration and logarithmic subtraction. Lesions were evaluated for the presence, morphology, and kinetics of enhancement. Lesion type, size, and pathologic findings were correlated with the findings at contrast-enhanced Digital Mammography. RESULTS: At contrast-enhanced Digital Mammography, enhancement was observed in eight of 10 patients with biopsy-proved cancers. In one case of ductal carcinoma in situ and one case of invasive duc...

  • development of contrast Digital Mammography
    Medical Physics, 2002
    Co-Authors: Mia Skarpathiotakis, Martin J. Yaffe, Aili K. Bloomquist, Dan Rico, Serge Muller, Andreas Rick, Fanny Jeunehomme
    Abstract:

    Development of breast tumors is often accompanied by angiogenesis--the formation of new blood vessels. It is possible to image the effects of this process by tracking the uptake and washout of contrast agents in the vicinity of a lesion. In this article, a method for carrying out contrast subtraction Mammography on a full-field Digital Mammography unit is described. Spectral measurements and modeling were performed to optimize the choice of x-ray target, kilovoltage and x-ray beam filtration for contrast Digital Mammography (CDM) on an available Digital Mammography system. Phantom studies were carried out to determine the sensitivity of CDM to iodine. Detection of iodine area densities of 0.3 mg/cm2 is possible for a circular object with a radius of 1.3 mm, which allows detection of uptake levels in the breast typically seen with cancer and some benign breast conditions. It was found that with a molybdenum anode x-ray tube, copper filtration could be used to effectively shape the x-ray spectrum to maximize the proportion of x rays with energies above the k edge of iodine. Simple logarithmic subtraction was found to be adequate in suppressing background signals dependent on the x-ray beam intensity and background thickness of the breast. The total x-ray dose from the procedure ranges between 1 and 3 mGy, similar to that from a conventional single view film mammogram. A clinical pilot study is currently being carried out to evaluate this technique.

  • TH‐A‐351‐01: Digital Mammography: A Physician's Perspective
    Medical Physics, 2008
    Co-Authors: Jay R Parikh
    Abstract:

    Full field Digital Mammography (FFDM) represents an exciting new frontier in the evaluation of breast cancer. FFDM separates out the components of image acquisition,image processing and image displays compared to traditional film screen Mammography, allowing a variety of potential technical advantages. In the ACRIN study FFDM had higher sensitivity for detecting breast cancer compared to SFM in premenopausal women, perimenopausal women, and women with dense breasts. Other reported advantages of Digital Mammography include higher contrast resolution, reduced noise, reduced need for repeat exposures and thus lower radiation dose to the patient, rapid soft‐copy display image interpretation, linkage to PACS systems and advanced applications such as CAD, teleMammography and new‐modality imaging such as contrast‐enhanced Digital Mammography, dual‐energy subtraction Mammography, stereo‐Mammography, and tomosynthesis. Digital Mammography has not yet received widespread clinical implementation because of several barriers. Significant costs associated with hardware purchase, additional equipment, professional retraining and development and technical support are incurred by facilities that choose Digital Mammography. Ongoing operational issues include comparing Digital versus film screen images in the radiologist and technologist work stations. Lastly, while storage may be rapid, reliable and convenient with Digital Mammography, significant sizable amounts of computer memory will ultimately be required to store the amount of data required to maintain high‐quality images. Educational Objectives: 1. To review the clinically relevant functional components of Digital Mammography. 2. To introduce some of the advanced applications of Digital Mammography. 3. To discuss some barriers to widespread clinical use of Digital Mammography. 4. To review data from clinical trials rerarding Digital Mammography. Outline: (1) Why Digital? (2) Functional components (3) Advanced applications (4) Barriers (5) Clinical trials

  • Full-Field Digital Mammography Workflow
    Seminars in Breast Disease, 2006
    Co-Authors: Margarita Zuley, Jay R Parikh
    Abstract:

    Within the United States, breast centers are actively transitioning from screen-film Mammography to full-field Digital Mammography. Mammography departments can take many lessons from the rest of radiology when considering the conversion from analog to Digital imaging. Just as in the rest of radiology, understanding and planning for the workflow changes that will occur are critical to a seamless conversion. This transition will affect all aspects of patient care in the department, and must be done within the fiscal limitations confronting breast centers. To a large degree, the workflow is dependent on the equipment that is purchased. The purpose of this article is to outline critical operational workflow considerations during the transition to full-field Digital Mammography.

  • Digital Mammography: current capabilities and obstacles.
    Journal of the American College of Radiology : JACR, 2005
    Co-Authors: Jay R Parikh
    Abstract:

    Digital Mammography represents an exciting new technology for breast imaging and possibly breast screening. The decoupling of functional components in Digital Mammography translates into potential operational efficiencies compared with screen-film Mammography (SFM). Digital Mammography is a platform for advanced applications not possible with traditional SFM. However, for Digital Mammography to replace SFM in daily clinical practice, operational and clinical hurdles will have to be overcome.

  • Perspective on Digital Mammography.
    Seminars in roentgenology, 2001
    Co-Authors: Etta D. Pisano, Cherie M Kuzmiak, Marcia Koomen
    Abstract:

    Summary Digital Mammography, particularly through its advanced applications, holds great promise for improved diagnostic accuracy, but the display of the images is not ideal at present. Clinical softcopy workstations are somewhat unwieldy to use, and image processing has not yet been optimized for each machine or for each clinical task. In addition, the cost-effectiveness and accuracy of the technology warrant careful study before Digital Mammography becomes widely disseminated and potentially replaces screen-film Mammography, a technology that has been well documented to reduce breast cancer mortality 99,30 .
