  • ORIGINAL RESEARCH Diagnostic Value of Multidetector-Row CT Angiography in the Evaluation of Thrombosis of
    2015
    Co-Authors: The Cerebral Venous Sinuses, K Seelos, Jennifer Linn, B. Ertl-wagner, M Reiser
    Abstract:

    BACKGROUND AND PURPOSE: The diagnosis of Cerebral venous and sinus thrombosis (CVST) as a rare but important cause of stroke is challenging.We aimed to investigate the diagnostic value of multidetector-row CT angiography (MDCTA) as a fast and cost-effective imaging tool in diagnosing CVST. MATERIALS AND METHODS: Nineteen patients who presented with clinical symptoms of a possible CVST were included. All patients had received both MDCTA and MR imaging with venous MR-angiography. Three blinded readers were asked to identify the Cerebral sinuses and Veins in MDCTA and to evaluate the presence of CVST in MDCTA. Consensus reading with interpretation of the MR imaging served to establish the definite diagnosis. RESULTS: The consensus reading revealed CVST in 10 of the 19 patients. With MDCTA, the venous sinuses could be identified in 99.2 % and the Cerebral Veins in 87.6 % of cases. The sensitivity and specificity of MDCTA for the diagnosis of CVST were 100%. CONCLUSION: Our study demonstrates that MDCTA provides excellent sensitivity and specificity for the diagnosis of CVST. Further studies are needed to evaluate the diagnostic potential of MDCTA in specific subsets of the general entity of CVST such as cortical venous thrombosis, thrombosis of the cavernous sinus, and thrombosis of the Internal Cerebral Veins

  • relative value of sliding thin slab multiplanar reformations and sliding thin slab maximum intensity projections as reformatting techniques in multisection ct angiography of the cervicocranial vessels
    American Journal of Neuroradiology, 2006
    Co-Authors: Birgit Ertlwagner, Roland Bruening, Jeffrey D Blume, R T Hoffmann, S Muellerschunk, Brad Snyder, M Reiser
    Abstract:

    BACKGROUND AND PURPOSE: To investigate image quality and vascular delineation of multisection CT (MSCT) angiography of the cervicocranial vessels with sliding-thin-slab (STS) maximum intensity projections (MIP) and multiplanar reformations (MPR). MATERIALS AND METHODS: Ten patients examined with a standardized protocol on a 16-section MSCT were included in the study. The data were reformatted as MIP and MPR in 3 planes for each subject; both reformatting techniques were applied in an STS technique with an increment of 3 mm. Images were evaluated independently by 3 blinded readers grading image quality parameters and vascular delineation of supra-aortic arteries and Veins. An extension of the Mantel-Haenzel row mean score test was used to compare the distribution of scores for vascular delineation and image quality between STS MIP and STS MPR. RESULTS: STS MIP reformations were significantly superior to STS MPR in the delineation of all extra- and intracranial arteries and arterial segments and in the delineation of the cavernous sinus and the Internal Cerebral Veins (P CONCLUSION: Because STS MIP reformations were preferred to or equal to STS MPR in all aspects, we recommend STS MIP as the primary reformatting technique in MSCT angiography of the cervicocranial vessels in addition to viewing the source images.
