We report CT findings in seven patients with diffuse cerebral edema and increased attenuation in the basilar cisterns resembling subarachnoid hemorrhage. On the basis of autopsy (three cases) and lumbar puncture (four cases) findings, true subarachnoid hemorrhage was reasonably excluded. Pathophysiologic changes that occur with diffuse cerebral edema are explored, with proposed explanations for...

For a huge variety of inspection tasks, high resolution computed tomography (CT) has become a powerful inspection tool. CT systems are applied in failure analysis as well as in 3D Metrology. Especially for complex automotive components with hidden internal structures CT offers a wide expansion of customary two-dimensional X-ray inspection capabilities. Depending on the sample size and the mater...

Traumatic brain injury (TBI) is a common cause of death and disability, worldwide. Early determination of injury severity is essential to improve care. Neurofilament light (NF-L) has been introduced as a marker of neuroaxonal injury in neuroinflammatory/-degenerative diseases. In this study we determined the predictive power of serum (s-) and cerebrospinal fluid (CSF-) NF-L levels towards outco...

INSERM UMR 1101, LaTIM, Brest, France Current MR attenuation correction (AC) approaches suffer from the lack of precision in the detection of bone and the assigned attenuation coefficients. In general, no unique transformation of MR image intensities into attenuation coefficients exists. The purpose of this work is to derive attenuation coefficient maps from a single MR sequence through the gen...

in this paper, some results of the chebyshev type integral inequality for the pseudo-integral are proven. the obtained results, are related to the measure of a level set of the maximum and the sum of two non-negative integrable functions. finally, we applied our results  to the case of comonotone functions.

Results The CT images in each patient revealed diffuse hyperdensity in the basal cisterns in an appearance similar to aneurysmal SAH. None of the patients had the typical distribution of nonaneurysmal perimesencephalic-SAH. In two of the patients, the prospective CT interpretation by the radiologist cited true SAH as the etiology of this increased attenuation within the subarachnoid spaces. In ...

A computer-aided diagnosis (CAD) system that characterizes nodules in medical images can help radiologists determine its malignancy. Preparing large volumes of labeled data for CAD systems, however, requires advanced knowledge. This makes it extremely difficult to develop such despite their growing demand. In this paper, we propose a new training method build an image classifier characterizatio...

The ossification of the anterior skull base, especially the lamina cribrosa, has been studied by computed tomography and histopathology. Sixteen human fetuses, (referred to our laboratory for pathological examination after spontaneous abortion between 18 and 32 weeks of gestation) and three infants, (1, 2 and 6 years of age, respectively) were examined. The cartilaginous preformation of the ant...

OBJECTIVES Carotid artery pseudo-occlusion is a rare condition and its natural history and clinicopathological characteristics are not well defined. We reported our 7-year experience in the surgical treatment of carotid artery pseudo-occlusion to determine the real benefit of the surgical option. METHODS From January 2006 to December 2013, 1414 patients were treated for high-grade stenosis of...
