For study group, transfemoral cerebral angiography-proven lesions were included, while 1:1 matched control group with MR angiography were included. Image features of SWI were evaluated.

In the study group (N\u2009=\u200955), 21 patients (38.2%) had VAD, while 34 patients (61.8%) had UIA. For SWI-detectable VAD, larger parent artery (PA)-dilatation ratio was observed (1.36 vs. 1.84, p\u2009=\u20090.034). For SWI-detectable UIA, larger PA-dome ratio (1.32 vs. 1.90, p\u2009=\u20090.020) and larger PA-height ratio (1.25 vs. 1.77, p\u2009=\u20090.005) were observed. The diagnostic performance and kappa values for VAD with stenosis were as follow: sensitivity: 91.7 (95% CI: 61.5\u201399.8); specificity: 93.9 (95% CI: 87.2\u201397.7); \u043a: 0.80. The diagnostic performance for UIA larger than 7\u2005mm were as follow: sensitivity: 87.5 (95% CI: 47.4\u201399.7); specificity: 95.1 (95% CI: 88.9\u201398.4); \u043a: 0.73.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SWI-detectable lesions were VAD with larger PA-dilatation ratio, and UIA with larger PA-dome ratio, and PA-height ratio.
