Breast screening: The new high-tech, simpler approach

In two years, 3D screening has picked up more early cancers than mammography while cutting down on the number of callbacks. One radiologist calls it “a game changer.”

October 2013) No woman wants to get a call that her radiologist has found a suspicious image on her mammogram, and then learn that she might need a biopsy—only to find out it was all a false alarm. Now, thanks to new technology, fewer women will get those calls.

Digital breast tomosynthesis, or 3-D mammography, is transforming breast screening by significantly reducing callbacks while picking up more cancers, and eliminating some of the fear and anxiety many women experience. All women who visit the Breast Center at Smilow Cancer Hospital at Yale-New Haven for mammography are now getting tomosynthesis over plain 2D mammography, says Liane Philpotts, MD, chief of breast imaging for the Breast Center.

Sugar makes cancer light-up in MRI scanners

A new technique for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI) has been unveiled by UCL scientists. The breakthrough could provide a safer and simpler alternative to standard radioactive techniques and enable radiologists to image tumours in greater detail.

The new technique, called ‘glucose chemical exchange saturation transfer’ (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth. (more…)

What a difference a 3-D makes

3-D CT scans give the U a leg up in spotting veterinary injuries

When Gauge fell from a rooftop a few months ago, he had two strikes against him:

• The ground was five stories down

• He was a dog, not a cat

Rushed to the University of Minnesota Veterinary Medical Center, Gauge looked like a goner. Even after his internal injuries were tended to, his fractured pelvis loomed like a third strike that would hobble him for life. That’s what it’s like for too many animals, whose veterinary surgeons have only conventional X-rays or a stack of two-dimensional CT scans to guide them as they go into surgery.  (more…)
