RATIONALE: A computer-aided detection program may help doctors find breast cancer sooner, when it may be easier to treat, in women undergoing screening mammography. PURPOSE: This randomized clinical trial is studying how well computer-aided breast cancer detection works in women undergoing screening mammography.
The purpose of this study is to develop computer programs to assist radiologists in finding breast cancer on mammograms and to compare the computer's accuracy of detecting cancers on direct digital and film mammograms.
Prostate cancer is currently detected by ultrasound-guided biopsy. Computer-aided diagnostic (CAD) systems based on multiparametric MRI are now capable of detecting most aggressive cancer foci non-invasively, but additional progress is needed for the technique to be accepted in clinical practice. We hypothesize that combining MRI and ultrasound imaging can improve the detection of cancerous tumors. As a first step in this direction, we need to create a database with MR images, ...
The purpose of this case collection effort is software design by R2 Technologies, Inc., The information received from Women's Imaging will be provided to the Case Collection, Data Management and Algorithm/software design and development teams who are responsible for the receipt of patient data and management of such data; and creation, testing and validation of R2 Technologies, Inc., for Computer Aided Detection (CAD) and new digital image archiving software design.
The purpose of this study is to develop a computer-aided diagnosis system to find breast lesions, including masses and microcalcifications, which hopefully will improve breast cancer detection and classification.
This study will develop and evaluate new techniques for computer-aided detection and diagnosis (CAD) of medical problems using images from diagnostic tests such as computed tomography (CT), ultrasound, nuclear medicine and x-ray images. The Food and Drug Administration has approved CAD techniques for detecting masses and calcifications on mammography and lung nodules using chest x-rays. Many other applications of CAD would potentially benefit patients. This study will explor...
This is a feasibility study to evaluate dual-energy (DE) contrast-enhanced (CE) digital mammography to detect breast cancer in patients with increased breast density (BI-RADS category c or d). Eligible patients will be invited to have full-field digital mammography and dual-energy (DE) contrast-enhanced (CE) digital mammography to compare accuracy of the imaging methods for the detection of breast cancer.
In March 2009, Health Canada approved Tomosynthesis for use in screening and diagnosis of breast cancer. The Tomosynthesis technology is designed as a complementary imaging model that is incorporated into the 2D Mammography system. This new imaging system has the capability to provide 2D, 3D and combination mode models. It consists of generating thin slice images that can be viewed individually as multiple images from the same breast. Tomosynthesis provides improved visibility ...
This randomized phase III trial studies digital tomosynthesis mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis mammography may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.
The purpose of this study is to compare 3D mammography with digital mammography in women with dense breasts for the detection and evaluation of masses and/or breast cancer.
Breast cancer remains a worldwide big killer with a rate of deaths compared with newly diagnosed cases not lower than 20%. Mammography is the primary imaging modality for the early detection of clinically occult breast cancer. Mammography is established as the primary investigation for population-based breast cancer screening. Advances in mammographic technique regarding both hardware and software applications are still not sufficient to overcome mammography's limitation with r...
Mammography remains the current standard in the detection of breast cancer. However, conventional two-view mammography will not detect all cancers. The major limiting factor of conventional mammography is the presence of superimposed breast tissue that can obscure clinically significant lesions. It is this limitation that decreases the sensitivity of mammography and leads to false negative results. The recent development of digital detectors has allowed imaging technologies...
This is a prospective, non-randomized, multi-center study to assess safety and long-term patency of the ostia treated with the XprESS device per the device indication for use (IFU).
An NBI-based diagnosis requires training and experience. We are developing a system of computerized image recognition, which can detect possible NBI features of polyps, and provide a more objective diagnosis, which allows nonexpert endoscopists to achieve a high diagnostic accuracy.
The objective of this study is to demonstrate that digital breast tomosynthesis (DBT) in combination with full field digital mammography (FFDM) has the potential to reduce significantly baseline screening recall rates without a loss in the detection of cancers. The primary hypothesis of the study is that DBT in combination with FFDM will reduce baseline screening mammography recall rates in negative examinations by at least 20%.
This randomized phase II trial studies how well abbreviated breast magnetic resonance imaging (MRI) and digital tomosynthesis mammography work in detecting cancer in women with dense breast. Abbreviated breast MRI is a low cost procedure in which radio waves and a powerful magnet linked to a computer and used to create detailed pictures of the breast in less than 10 minutes. These pictures can show the difference between normal and diseased tissue. Digital tomosynthesis mammogr...
Advances in digital dentistry coupled with increased demand for aesthetic restorations have led to developments in CAD CAM( Computer Aided Design and Computer Aided manufacturing)systems for manufacturing tooth restorations. CAD CAM restorations have the added benefit of digital impressions which eliminate the need to take conventional impressions, something patients find difficult to tolerate. CAD CAM restorations are now part of routine dental care. However there are no clini...
Breast tumors are normally seen with mammography or ultrasound without the use of a dye but the size and extent of the tumor may be hard to see. Currently, after initial mammography, many patients undergo bilateral breast MR to further stage the local tumor. It is able to not only detect anatomic abnormalities but can also evaluate changes such as the development of new blood vessels, which occurs with the development of cancers. MRI is extremely sensitive and detects unsuspect...
The overall objective of this study is to evaluate whether polarized or green filtered digital imaging can assist clinicians to screen for premalignant lesions in the cervix. The specific aims of the study are: - To compare polarized and green filtered digital images of the cervix, to standard white light images, colposcopic evaluation and to pathologic analysis of biopsied tissue. - To develop algorithms to discriminate between normal and abnormal tissue based on...
Linked color imaging (LCI)，a new endoscopy modality, creates clear and bright images by using short wavelength narrow band laser light. LCI can make red area appear redder and white areas appear whiter. Thus, it may be possible to distinguish adenoma and non-adenoma polyps based on color evaluation of LCI images. This study aimed to assess the correlation between histology results and LCI images. Moreover, we conducted a pilot study to explore the clinical potential of LCI to...
Hypothesis: A higher sensitivity to breast cancer detection can be achieved in women with dense breast tissue by performing and reviewing results of Automated Breast Ultrasound (ABUS) and Digital X-Ray Mammography (XRM) together as part of routine screening compared to performing and reviewing results of XRM alone. Primary Objective: For the cohort of asymptomatic women who have dense breast tissue, calculate the sensitivity of Digital X-Ray Mammography (XRM) and ABUS together...
Tomosynthesis is a new digital mammographic tool which can be performed at the same time as routine screening mammography. It creates CT-like slices through the breast, minimizing the tissue overlap. Tomosynthesis has the potential to improve screening mammography outcomes by increasing cancer detection rate, decreasing false negative rates and false positive rates. This trial will help determine if tomosynthesis is useful in a screening setting.
