CT angiographic source images: flow- or volume-weighted?
BACKGROUND AND PURPOSE CTA-SI have been previously reported to correlate with CBV. We hypothesized that CTA-SI performed by modern multisection CT scanners are CBF-, not CBV-weighted. MATERIALS AND METHODS Sixty-four consecutive patients with anterior circulation stroke symptoms were selected from a stroke data base between June 2007 and January 2009. Two independent blinded readers calculate...
متن کاملCT angiographic source images predict outcome and final infarct volume better than noncontrast CT in proximal vascular occlusions.
BACKGROUND AND PURPOSE Alberta Stroke Programme Early CT Score (ASPECTS) is widely used for assessment of early ischemic changes in acute stroke. We hypothesized that CT angiography source image (CTA-SI) ASPECTS correlates better with baseline National Institutes of Health Stroke Scale score, final ASPECTS and neurological outcomes when compared with noncontrast CT ASPECTS. METHODS We studied...
متن کاملAcute brain infarct: detection and delineation with CT angiographic source images versus nonenhanced CT scans.
PURPOSE To retrospectively compare sensitivity and specificity of admission nonenhanced computed tomographic (CT) scans with those of CT angiographic source images in detection of early ischemic changes in middle cerebral artery (MCA) stroke and to retrospectively compare admission nonenhanced CT scans with CT angiographic source images in delineation of final infarct extent, with follow-up ima...
متن کاملCT angiographic source images with modern multisection CT scanners: appropriate injection protocol is crucial.
Multisection CT Scanners: Appropriate Injection Protocol Is Crucial I have read with great interest the recently published article of Sharma et al. The study compared CT angiographic source imaging (CTASI) performed by a modern multisection CT scanner with cerebral blood flow (CBF) and cerebral blood volume (CBV) maps derived from dynamic CT perfusion in patients with acute ischemic stroke. The...
متن کاملDual-source CT coronary angiographic evaluation of coronary artery fistulas
The aim of the present study was to retrospectively evaluate the incidence and morphological features of coronary artery fistulas (CAFs) detected by dual-source computed tomography coronary angiography (DS-CTCA). Between January 2011 and January 2013, 19,584 consecutive patients that had undergone electrocardiogram-triggering DS-CTCA were retrospectively reviewed. Image reconstructions were per...
