CT angiography source images with modern multisection CT scanners: delay time from contrast injection to imaging determines correlation with infarct core.
CT Scanners: Delay Time from Contrast Injection to Imaging Determines Correlation with Infarct Core We have read with great interest the letter by Dr Kloska and a subsequent reply concerning a study by Sharma et al, investigating the perfusion imaging correlate of CTA source image (CTA-SI) lesions and would like to share our own data on this subject. On the basis of our findings, we agree with ...

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 کاملCT angiography source images predict final infarct extent in patients with basilar artery occlusion.
BACKGROUND AND PURPOSE The posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) is a 10-point grading system to quantify ischemic changes in the posterior circulation. We analyzed whether pc-ASPECTS on CT angiography (CTA) source images (CTASI) predicted the final infarct extent and hemorrhagic transformation (HT) rate in patients with basilar artery occlusion. MATERIALS A...
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 کاملSimultaneous cervical CT angiography from routine contrast-enhanced neck CT with multi-detector CT scanning
84 ● M a r t 2 0 0 1 C omputed tomographic angiography (CTA) is a technique that has evolved in a rapidly changing interplay of hardware and software advances. CT scan times are becoming ever shorter, now allowing imaging of larger segments of arterial anatomy during circulation of the intravenous bolus of contrast material. Multidetector (or multislice) CT is the most recent dramatic advance t...
