MR perfusion helps diagnose brain lesions
By Eric Barnes
In traditional MRI, both cerebral abscesses and high-grade tumors can be depicted as rim-enhancing lesions, rendering them indistinguishable. But researchers at Duke University say MR perfusion imaging can tell the two apart, based on tumors' increased vascularity.

In living color: Stanford researchers peer into human visual system with fMRI
By Shalmali Pal
On a daily basis, the majority of people in the world take their ability to perceive color for granted. But how exactly does the human visual system interpret color and what drives that interpretation? Researchers at a lab dedicated to vision and imaging technology at Stanford University are hoping to answer that question with the help of functional MRI.

New interventions show promise in battling head and neck cancers
By Shalmali Pal
Two new weapons have emerged in the fight against head and neck cancer. Israeli investigators have released early data indicating that the experimental drug Multikine can reduce tumors significantly. In other news, the gene-deleted adenovirus Onyx-015, when paired with chemotherapy, also has the potential to shrink head and neck tumors, and prevent them from recurring.
