We present a case of isolated thrombosis of the internal cerebral veins and the vein of Galen diagnosed on CT and MRI, and we review the literature. We emphasize the pathognomonic signs on CT and MRI necessary for an early diagnosis(More)
In this paper we compare a semi-automated delineation method with totally manual delineation for area quantification, with respect to efficiency, quality, and intra- and interobserver variability. Liver lesions on 28 CT images were delineated by three observers, twice using completely manual delineation and twice using a semi-automated method. Quantitative(More)
The purpose of this article is to review less common presentations of degenerative disc disease on MR imaging. The images of eight patients were retrospectively analyzed. Six of them had transligamentous (or noncontained) disc herniations, the fragments of which were located in the posterior epidural space in three of them. One patient had a transdural disc(More)

PURPOSE The purpose of this study was to investigate the influence of different parameters (object size, shape, orientation, contrast, observer, and window setting) on the accuracy of volume measurements in spiral CT. METHOD The phantom study consisted of two parts. First, well-circumscribed ellipsoid objects were scanned with conventional and spiral CT.(More)
