Researchers have developed new methods for segmenting small blood vessels in the brain using ultra-high resolution 7T MRI scans. The SMILE-UHURA challenge provided a dataset and platform for developing machine learning algorithms, with submitted deep learning methods achieving reliable segmentation performance, reaching Dice scores up to 0.838. Separately, a new local-sensitive connectivity filter (LS-CF) was proposed to improve existing vessel segmentation techniques like the Frangi filter, showing competitive results across various multimodal datasets and outperforming state-of-the-art approaches on specific datasets.
