Establishing final infarct volume: stroke lesion evolution past 30 days is insignificant.
BACKGROUND AND PURPOSE Lesion volume measured on MRI has been used as an objective surrogate marker for outcome in clinical trials. However, lesion volumes vary over time because of edema and tissue loss. This study aims to determine if lesion volumes measured at 30 and 90 days after ictus significantly differ. METHODS We performed a retrospective study of 18 patients who had acute (<24 hours...
متن کاملComputed tomographic angiography and cerebral blood volume can predict final infarct volume and outcome after recanalization.
BACKGROUND AND PURPOSE Recanalization rates are higher in acute anterior stroke treated with stent-retrievers when compared with older techniques. However, some still have sizeable infarcts and poor outcome. This may be related to underestimation of core infarct on nonenhanced computed tomography (NECT). CT angiography (CTA) source images (CTASI) and CT perfusion may be more informative. We hyp...
متن کاملDo acute diffusion- and perfusion-weighted MRI lesions identify final infarct volume in ischemic stroke?
BACKGROUND AND PURPOSE An acute mismatch on diffusion-weighted MRI (DWI) and perfusion-weighted MRI (PWI) may represent the "tissue-at-risk." It is unclear which "semiquantitative" perfusion parameter most closely identifies final infarct volume. METHODS Acute stroke patients underwent DWI and PWI (dynamic-susceptibility contrast imaging) on admission (baseline), and T2-weighted imaging (T2WI...
متن کاملComparison of Perfusion CT Software to Predict the Final Infarct Volume After Thrombectomy.
BACKGROUND AND PURPOSE Computed tomographic perfusion represents an interesting physiological imaging modality to select patients for reperfusion therapy in acute ischemic stroke. The purpose of our study was to determine the accuracy of different commercial perfusion CT software packages (Philips (A), Siemens (B), and RAPID (C)) to predict the final infarct volume (FIV) after mechanical thromb...
متن کاملFinal cerebral infarct volume is predictable by MR imaging at 1 week.
BACKGROUND AND PURPOSE Stroke volume, an increasingly used end point in phase II trials, is considered stationary at least 30 days after the ictus. We investigated whether information conveyed by MR imaging measurements of the "final" infarct volume could be assessed as early as the subacute stage (days 3-6), rather than waiting for the chronic stage (days 30-45). MATERIALS AND METHODS Ninety...
