From: ASL and susceptibility-weighted imaging contribution to the management of acute ischaemic stroke
A 72-year-old patient with right homonymous lateral hemianopsia. DWI (a), 3D TOF (b), minimum intensity projection (c), and multiplanar reconstruction (d) of the SWAN sequence in the axial plane. a Acute ischaemic lesion in the territory of the left posterior cerebral artery. b No visualisation of the left P2 (white arrow). c and d Susceptibility vessel sign in P2 (curved arrow). d TOF effect of the SWAN sequence identifies the susceptibility vessel sign associated with the thrombus and the upstream arterial segment (arrowhead)
