The sensitivity of T2*, SWAN source images, 2D SWAN, and SWAN MinIP were, respectively, of 89.3%\/82.1%, 82.1%, and 82.1% for dural sinus thrombosis and of 100%\/100%\/100%\/96.6% for cortical venous thrombosis. There were significant differences in thrombus detection between T2* and SWAN: T2* versus SWAN source images and 2D SWAN ( p = 0.04) and versus SWAN MinIP ( p = 0.03). There were no significant differences between the three modalities of SWAN images. T2* was more sensitive than all SWAN images for both sigmoid sinus thrombosis and intracranial internal jugular vein thrombosis ( p = 0.04). Inter-observer agreement was slightly superior with T2* ( p &lt; 0.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this small cohort, SWAN sequence at 3T did not yield additional value for thrombus detection in acute CVT compared to T2*.
