Mammography screening has limited performance in young women or women with dense breasts although it is the only proven method for breast cancer screening that reduces the mortality. The investigators propose a multicenter trial of breast cancer screening to assess the effectiveness of supplemental ultrasonography for Korean women aged 40-59 years.
The investigators will screen same consecutive participants using both methods; digital mammography plus supplemental ultrasonography (intervention arm) and digital mammography only (control arm) for 5 years. The investigators will collect follow-up information by assessment of screening records, questionnaire, and official cancer registry. The primary outcome will be sensitivity, specificity, recall rate, cancer detection rate and stage distribution at the end of first round of screening. The secondary outcome will be cost-effectiveness and cost-utility of digital mammography with ultrasonography versus digital mammography only for breast cancer screening. It is hoped that the results of this trial will provide guidance of effective breast cancer screening strategy to women aged 40-59, especially with dense breasts.

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 direc...
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 conventio...

RATIONALE: Screening tests may help doctors find cancer cells early and plan better treatment for breast cancer. It is not yet known whether positron emission mammography is more effective...
The purpose of this study is to evalute whether CAD (computer-aided detection) in FFDM (full-field digital mammography) can facilitate the detection rate of breast cancer on mammography co...
Purpose To evaluate the early implementation of synthesized two-dimensional (s2D) mammography in a population screened entirely with s2D and digital breast tomosynthesis (DBT) (referred to as s2D/DBT)...
Full-field digital mammography (FFDM) has replaced screen-film mammography (SFM) in most breast cancer screening programs due to technological advantages such as possibilities to adjust contrast, bett...
Full-field digital mammography (FFDM) has largely replaced film-screen mammography in the US. Breast density assessed from film mammograms is strongly associated with breast cancer risk, but data are ...
Contrast-enhanced digital mammography (CEDM) is a new breast imaging technique. The role of CEDM in the surgical management of breast cancer has not yet been characterized.
Estimates of risk for radiation-induced breast cancer from mammography screening have not considered variation in dose exposure or diagnostic work-up after abnormal screening results.
Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Minimally invasive procedures, diagnostic or therapeutic, performed within the BLOOD VESSELS. They may be perfomed via ANGIOSCOPY; INTERVENTIONAL MAGNETIC RESONANCE IMAGING; INTERVENTIONAL RADIOGRAPHY; or INTERVENTIONAL ULTRASONOGRAPHY.
Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.
