This study aimed to investigate whether quantitative T\n                    <jats:sub>2<\/jats:sub>\n                    relaxometry is a suitable imaging biomarker for the assessment of tissue changes related to cognitive abnormalities in patients with SVD. 39 patients and 18 age-matched healthy control subjects underwent 3 T magnetic resonance imaging (MRI) with T2-weighted multiple spin echo sequences for T\n                    <jats:sub>2<\/jats:sub>\n                    relaxometry and DTI sequences, as well as comprehensive cognitive assessment.

In SVD patients, quantitative T\n                    <jats:sub>2<\/jats:sub>\n                    values were significantly increased compared to controls (p\u2009=\u20090.002) and significantly negatively correlated with the global cognitive performance (r= \u20130.410, p\u2009=\u20090.014) and executive function (r= \u20130.399, p\u2009=\u20090.016).
