Digital tomosynthesis shows promise over conventional film mammography as a more specific breast screening technique and a more accurate diagnostic technology, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"The results of our preliminary trial suggest that tomosynthesis may decrease false-positive screening mammography findings by half, thereby reducing the number of women who are recalled after screening mammography for a second, more thorough exam," said lead author Steven Poplack, M.D., associate professor of diagnostic radiology and obstetrics and gynecology at the Dartmouth Hitchcock Medical Center/Dartmouth Medical School in Lebanon, N.H.
A patients experience is much the same for tomosynthesis as it is for a standard mammography exam. Tomosynthesis obtains digital data that can be manipulated and displayed in a variety of ways, including paging through or cine display of thin (one millimeter) sections or slices of breast tissue, which eliminates the problem of overlying tissue that might be mistaken for lesions or that may hide small cancers.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
