Screening mammograms are used to check for breast cancer in asymptomatic women (breast cancer: screening).
Mammograms are breast X-rays, added to those usually ? 2 views of each breast at different angles belong. The breasts are compressed with plastic shovels to optimize the visualization of the breast tissue and abnormalities. Screening mammograms are used to check for breast cancer in asymptomatic women (breast cancer: screening). Diagnostic mammograms are used to diagnose breast disease in women with breast symptoms palpable lesions of pathological values ??of mammography screening that require further investigation. Among the diagnostic mammograms standard and special views can include. Usually mammography exposes the breasts to about 0.4 mSv of radiation. This dose is compared to other imaging methods using radiation, relatively low (see Table: Typical radiation doses *). However, the radiation exposure is a concern in mammography because the breast tissue is sensitive to radiation (risks Medical radiation). Mammography is sometimes recommended for women> 40; partly because the breast tissue is less susceptible to the adverse effects of radiation in older women. Special mammography centers and digital imaging techniques are used to minimize radiation exposure. Variations of mammography tomosynthesis, a 3-dimensional technique can be used in mammography. In tomosynthesis is an X-ray source moves through an arc of deflection, whereby thin tomographic slices to be reconstructed into 3-dimensional images. This technique minimizes the effect of the overlapping structures in the breast. Thus can be better separated from the background anomalies. As a result, the need for repeat mammograms can be reduced and doctors may be able to detect cancers more precisely, especially in patients with dense breast tissue. The total dose of radiation (1.0 mSv) is used in the 3-dimensional mammography, is higher than that of conventional mammography (0.5 mSv). Although this is relatively low compared with other imaging tests.
