The absence of the Susceptibility Vessel Sign (SVS) on baseline MRI is associated with the presence of active and occult malignancy in patients with acute ischemic stroke eligible for mechanical thrombectomy. SVS absence may increase the chance of detecting paraneoplastic coagulation disorders and occult malignancy in acute ischemic stroke patients. One of the clinical applications of susceptibility-weighted imaging in brain MRI is the detection, in the acute stage of stroke, of intravascular thromboembolism, called the SVS. The presence of SVS on gradient-echo imaging or susceptibility-weighted imaging is strongly associated with a high proportion of red blood cells and a low proportion of fibrin and platelets in retrieved thrombi on MRI, as well as the presence of active malignancy. A single-centre, retrospective, cross-sectional study, presented by Dr Morin Beyeler (Bern University Hospital, Switzerland), hypothesised that the absence o...
