Switch to macrocyclic GBCAs reduces brain signals

By Wayne Forrest

As more studies weigh the risks and benefits of gadolinium-based contrast agents (GBCAs), German researchers have discovered that switching from a linear GBCA to a macrocyclic GBCA reduced the level of residual signal intensity in the brains of patients who underwent multiple enhanced MRI scans with both types of agents.

4D CT brain segmentation offers subtle clues in stroke

By Eric Barnes

Wednesday, November 30 | 10:30 a.m.-10:40 a.m. | SSK15-01 | Room N229Dutch researchers have successfully segmented gray and white matter in the brain using 4D CT. The technique provides a subtle assessment of the health of the brain for stroke treatment, and it could be useful in further segmentation and anatomic labeling, according to the group.

fMRI beats polygraph test in detecting lies

By Wayne Forrest

The next time you think someone is telling a lie, give them a functional MRI (fMRI) scan instead of a polygraph test. Researchers found that fMRI experts were 24% more likely to detect a deception on fMRI than polygraph examiners were using polygraphy.
