    Accuracy of high resolution computed tomography in direct diagnosis of cerebral aneurysms (1987)
    Springer
    Neuroradiology 29 (1987), S. 152-159 
    Details
    ISSN: 1432-1920
    Keywords: Cerebral aneurysms ; Computed tomography ; Cerebral angiography ; Subarachnoid hemorrhage

    Notes: Summary With high resolution computed tomography (CT) of the skull, performing rapid series of 1.5 mm slices during an intravenous bolus injection of contrast medium, an angiography-like image (angio-CT) of the basal cerebral arteries can be obtained. From 76 consecutive angiographically or autopsy-verified cerebral aneurysms of vaious size down to 3 mm in diameter, 74 (97.4%) were shown up by the angio-CT. One ruptured and one incidental aneurysm escaped CT visualization. Besides the correct localization of the aneurysms, angio-CT provides information concerning the size and main direction of the aneurysms and yields, in addition, a coronal view of the aneurysms and their surrounding structures. Pitfalls for mis-diagnosis can be the following: Aneurysms of below 5 mm in diameter, located at the supraclinoid part of the carotid artery, multiple or non-ruptured aneurysms, bony or movement artefacts, poorly contrasted vessels due to wrong injection technique of contrast medium or vasospasm, and incorrect interpretation.

    High resolution computed tomography of superior sagittal sinus-thrombosis and-abnormalities (1989)
    Springer
    Neuroradiology 31 (1989), S. 307-311 
    Details
    ISSN: 1432-1920
    Keywords: Computed tomography ; Sinus thrombosis ; Sinus abnormalities
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Ten patients with suspected abnormalities or thrombosis of the superior sagittal sinus were studied by high resolution computed tomography using a thin slice technique after bolus injection. In all patients good visualization of the sinus pathology could be achieved, which correlated exactly with the findings in the 7 angiographically controlled cases.

    Dural arteriovenous fistula in the falx cerebri (1994)
    Springer
    Neuroradiology 36 (1994), S. 616-618 
    Details
    ISSN: 1432-1920
    Keywords: Arteriovenous malformations, dural ; Fistulae ; Angiography ; Computed tomography
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The case of a 73-year-old patient with a pure dural arteriovenous fistula within the falx cerebri, first manifested as subarachnoid and intraventricular haemorrhage is reported. There was no positive history for both the congenital and the acquired type of lesion. Computed tomographic findings and the relatively unusual angiographic features are discussed.

    Localization of central lesions by correlation of CT findings and neurological deficits (1992)
    Springer
    Acta neurochirurgica 119 (1992), S. 17-22 
    Details
    ISSN: 0942-0940
    Keywords: Computed tomography ; precentral gyrus ; pyramidal tract ; neurological findings ; central lesions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary In a prospective study involving 100 patients with lesions in the precentral gyrus or pyramidal tract we sought to correlate clinical findings and the results of an axial computed tomography (CT) to localize the lesion. In 85% of patients the size and location of the lesion visible on CT correlated well with the type and severity of the neurological symptoms and signs. However, in the remaining 15% of patients the CT findings did not correlate well with the patient's neurological deficit, showing that in these patients the anatomy of the central area was variable or distorted by the space-occupying lesion. We suggest that in such patients neurophysiological techniques be used intra-operatively for reliable localization of the motor strip.

    Localization of the precentral gyrus in the computed tomogram and its clinical application (1986)
    Springer
    Journal of neurology 233 (1986), S. 73-76 
    Details
    ISSN: 1432-1459
    Keywords: Anatomical landmarks ; Computed tomography ; Precentral sulcus ; Central gyrus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary In 30 patients the anatomical configurations of the precentral and central sulcus and gyrus were examined by computed tomography and could be determined with great accuracy. The distances between the coronal suture and the central and precentral fissure, and the angle between the longitudinal fissure and the central fissure were measured. These data are used in the precise localization for a surgical approach to a mass lesion.
