Clot interface Hounsfield unit ratio calculated by measuring the Hounsfield units in a region of interest selected at the proximal and distal clot interface only in scans that are mid- to late arterial- or appropriate venous-weighted. cirHU is calculated by dividing the proximal clot interface Hounsfield unit by the distal clot interface Hounsfield unit. In (a), a patient with a left M1 MCA clot has a cirHU of 1.05 while in (b), a patient with a left M1 MCA clot has a cirHU of 3.21 Adapted from Mishra et al. AJNR 2014 [26]
