3D/4D ultrasound imaging: Coming of age
January 4, 2013 -- Although high-performance 3D/4D technology has been available in ultrasound for years, it hasn't routinely been used in all clinical practices. That may change in 2013, however, thanks to a number of key trends that are expected to drive widespread adoption.
Yearly screening breast US benefits women with dense tissue
December 4, 2012 -- Although the optimal frequency of screening breast ultrasound for women with mammographically dense breast tissue remains under debate, study data presented at last week's RSNA 2012 meeting suggest that this population would benefit from yearly scans.
