Decreased oxygen saturation in asymmetrically prominent cortical veins in patients with cerebral ischemic stroke

Long‐term sequelae of hippocampal lesions in patients with transient global amnesia: A multiparametric MRI study

“…Paramagnetic substances in tissues cause local susceptibility changes. A recent study showed that the susceptibility value in the prominent cortical veins in the stroke hemisphere was significantly higher than that in the contralateral hemisphere and in healthy controls and in the meantime, the oxygen saturation in the prominent cortical veins was decreased, ranging from 16% to 44% relative to the veins of the contralateral hemisphere …”

Cortical vessel sign on susceptibility weighted imaging reveals clinically relevant hypoperfusion in internal carotid artery stenosis

“…In the recent studies with SWI, more prominent hypointense asymmetric and partially enlarged vessels were found in areas of hypoperfusion. The hypointense vessels were found to be a correlate of increased deoxyhemoglobin in this area [18]. All of these changes were shown to predict outcome and can be used to calculate a tissue at risk [13,14].…”

Susceptibility‐weighted imaging: current status and future directions

“…The potential of QSM has been demonstrated in a recent study, in which Xia et al . compared the susceptibility values of cortical veins in the left and right hemispheres of healthy controls, as well as in the contralateral hemisphere of stroke patients with APCVs. It was concluded that the occurrence of APCVs in ischemic stroke patients in SWI data was best explained by the increased deoxyhemoglobin concentration in the APCVs.…”
