According to a study published in the journal Radiology , a new technique called digital breast tomosynthesis (DBT) provides improved detection and lower false-negative rates in breast cancer screening. This technique is found to have better sensitivity and specificity than digital mammography. In DBT, an X-ray camera moves in an arc over the breast to acquire tissue images from different angles. The images are processed into 3-D structures that can be scrolled through a millimeter at a time.
This avoids the problem of tumors hidden in the overlapping tissues. The technique is also beneficial in screening dense breasts or those with a higher proportion of fibrous and glandular tissue than fatty tissues as cancerous tissues are difficult to detect in such breast structures. Thus, scientists are looking forward to making use of DBT in routine breast cancer diagnosis. Source: News Medical…
