CT 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 کاملCT 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 ...
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: 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 کاملA comparison of angiographic CT and multisection CT in lumbar myelographic imaging.
BACKGROUND AND PURPOSE The purpose of this work was to provide an intraindividual comparison of angiographic CT (ACT) and multisection CT (MSCT) in lumbar myelographic imaging and to evaluate possible benefits of ACT, which is a further development of rotational angiography providing image data of high spatial and CT-like contrast resolution. MATERIALS AND METHODS In 26 patients with degenera...
