Intracranial hemorrhage (ICH) volume estimation is important for patient management. ABC/2 is a validated method of volume estimation using CT (2). Differing appearance of blood across MRI imaging techniques and blood age limits the ability of MRI to evaluate ICH volume. The QSM technique mcTFI has features well suited to bleed measurement. In this study we show that the widely used ABC/2 CT technique for ICH volume measurement applied to mcTFI QSM MRI yields ICH volumes strongly correlated with those obtained using CT.
