Arterial hyperintensity on BLADE fluid-attenuated inversion recovery images (FLAIR) in hyperacute territorial infarction: comparison with conventional FLAIR

Abstract

Arterial hyperintensity is an important sign in patients with acute territorial infarctions. BLADE FLAIR sequences are sensitive for the detection of AH. BLADE FLAIR sequences provide better image quality by reducing artefacts.

Can FLAIR hyperintense vessel (FHV) signs be influenced by varying MR parameters and flow velocities? A flow phantom analysis

“…Recently, Kwag et al reported that the PROPELLER technique enhanced the FHV sign in acute MCA stroke patients (20). Our results also showed that PROPELLER technique strongly enhanced the degree of FHVs.…”

“…The PROPELLER technique has been implemented with conventional MR sequences to reduce motion artifacts and increase image quality (17)(18)(19). Recently, Kwag et al reported that the PROPELLER technique enhanced the FHV sign in acute MCA stroke patients (20). Our results also showed that PROPELLER technique strongly enhanced the degree of FHVs.…”

Hyperintense Vessels on T2-PROPELLER-FLAIR in Patients with Acute MCA Stroke: Prediction of Arterial Stenosis and Perfusion Abnormality

“…Gawlitza et al 23 reported that there was significant correlation between the degree of the FHV sign and PWI lesion volume, but they did not compare FHV signs with PWI territory by territory. Kwag et al 24 recently…”

Correlation between Hyperintense Vessels on FLAIR Imaging and Arterial Circulation Time on Cerebral Angiography

“…Although the difference in parameters may be trivial, this might have changed the appearance of HVs. 21…”
