By Shalmali Pal
Only a third of breast cancer patients who have endocrine therapy respond to treatment, and the current tests for patient selection are less than optimal. Some imaging techniques may not show results for several months post-treatment. Scintigraphy could be a better, noninvasive way to predict treatment response, according to European researchers.

Barium does a good job of tagging fluid and residual fecal material for virtual colonoscopy, although tweaking the dose and timing don't do much to reduce the small amount of stool that remains untagged, researchers from Belgium reported in a recent study. But adding a small extra dose of barium on the day of the VC exam can improve fluid tagging.
