To spot an incipient stroke, tiny brain probe acts ‘like a microscope’

Researchers have developed a tiny probe that can be inserted into microcatheters to visualize the arteries inside the brain. This technology, called neuro optical coherence tomography (nOCT), provides high-resolution images from inside the arteries, allowing for better understanding of problems like clots, plaque build-up, and tears in the artery lining. The study, published in Science Translational Medicine, demonstrates the potential of this miniaturized visualization tool in diagnosing and treating cerebrovascular diseases. The next step is gaining regulatory approval to market the probe, which could have significant implications for neurology and advance the field of neuroendovascular medicine.
