A new study published in the journal Biomedical Optics Express reports on the development of a new laser-based imaging tool.

On conducting an experiment in mice, the researchers were able to find that a month of chronic cocaine injection led to a dramatic drop in the blood flow speed, raising the risk of aneurysm-like bleeding and strokes.
“We show that quantitative flow imaging can provide a lot of useful physiological and functional information that we haven't had access to before. The resulting images are the first of their kind that directly and clearly document such effects”, co-author of the study, Yingtian Pan from the Stony Brook University in the US, said.
