The sophisticated type of artificial intelligence (AI) know as deep learning can help rapidly detect blockages in the arteries that supply blood to the head, potentially speeding the onset of life-saving treatment, according to a recently published study (Stib MT et al. Detecting Large Vessel Occlusion at Multiphase CT Angiography by Using a Deep Convolutional Neural Network. Radiology 2020 Sep 29;200334. doi: 10.1148/ radiol.2020200334).
