    Congenital absence and aberrant course of the internal carotid artery (1996)
    Springer
    European radiology 6 (1996), S. 650-654 
    Details
    ISSN: 1432-1084
    Keywords: Aberrant internal carotid artery ; Congenital absence of the internal carotid artery ; CT ; MRI ; MR angiography

    Topics: Medicine
    Notes: Abstract We retrospectively reviewed the imaging features of an aberrant course of the internal carotid artery (ICA) in one patient and its unilateral absence in four. Absence of the ICA was initially detected by MRI and MR angiography in both patients who underwent these examinations. CT revealed an abnormal or absent carotid canal in all cases. Radiological diagnosis by MRI and MR angiography could play an important role in the diagnosis.

    Notes: Abstract A 14-year-old boy developed acute quadriplegia, associated with sensory impairment and bowel and urinary dysfunction. MRI of the cervical cord showed diffuse increased signal intensity on T2-weighted images with gadolinium-diethylenetriamine penta-acetic acid enhancement. Based on the clinical presentation and MRI findings, the diagnosis of acute transverse myelitis was made. Enterovirus RNA was amplified from CSF by the reverse transcriptase-polymerase chain reaction. Serum neutralizing antibody to ECHO virus type 18 rose from 1/4 on admission to 1/16 2 months later. Conclusion This is the first reported case of acute transverse myelitis caused by ECHO virus type 18 infection.

    The anterior choroidal artery syndrome (1994)
    Springer
    Neuroradiology 36 (1994), S. 340-345 
    Details
    ISSN: 1432-1920
    Keywords: Infarcts, anterior choroidal artery ; CT ; MRI ; Angiography
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We reviewed 12 cases of infarcts in the territory of the anterior choroidal artery (AChA) on CT and/or MRI. In each case vascular occlusion in the region was verified angiographically. Although the extent of the lesion on CT/MR images was variable, all were located on the axial images within an arcuate zone between the striatium anterolaterally and the thalamus posteromedially. The distribution of the lesions on mutiplanar MRI conformed well to the territory of the AChA demonstrated microangiographically. The variability of the extent of the infarcts may be explained by variations in the degree of occlusive changes in the AChA or the development of collateral circulation through anastomoses between the AChA and the posterior communicating and posterior cerebral arteries. The extent of the lesion appeared to be closely related to the degree of neurological deficit.

    Bilateral anterior opercular syndrome: Localizing value of SPECT and MRI (1988)
    Springer
    Neuroradiology 30 (1988), S. 579-581

    ISSN: 1432-1920
    Keywords: Operculum syndrome ; Anterior opercular syndrome ; Foix-Chavany-Marie syndrome ; SPECT ; MRI

    Topics: Medicine
    Notes: Summary Bilateral anterior opercular syndrome is clinically characterized by facio-pharyngo-glossomasticatory diplegia due to bilateral opercular lesions. Reported cases of the syndrome have been relatively rare probably because of difficulty in determining opercular damage on clinical symptoms alone. We report a case of this syndrome in whom bilateral opercular damage could be detected not by CT, but suggested by SPECT, and confirmed by MR imaging.

    Liquid viscosities and densities of HFC-134a+glycol mixtures (1993)

    Keywords: density ; diethylene glycol ; ethylene glycol ; HFC-134a ; polyethylene glycol ; polypropylene glycol ; tetraethylene glycol ; triethylene glycol ; viscosity

    Topics: Physics
    Notes: Abstract Liquid viscosity and density of six binary mixtures of HFC-134a with glycols [ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol (400), and polypropylene glycol (2000)] have been measured in the temperature range from 273 to 333 K. The viscosity was measured by a rolling-ball viscometer calibrated with standard liquids of viscosities and densities (JS5, JS10, JS20, and JS50). The density was measured with a glass pycnometer. The uncertainties of the measurements were estimated to be less than 3.4 % for viscosity and 0.04 % for density, respectively. An equation is given to represent the obtained viscosity values as a function of weight fraction and temperature.

    Notes: Abstract The liquid viscosity of six binary mixtures of HFC-134a with glycols [ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol(400), and polypropylene glyco](2000)] was measured in the temperature range from 273 to 333 K. The viscosity was measured with an improved capillary viscometer instead of the rolling-ball viscometer reported in our previous work. The measurement uncertainty was estimated to be 1.6%. Most of the present data are higher than previous data, and the gap between the two sets of data increases further in low-viscosity regions. The present results obtained with laminar flow are more reliable than previous results, which are indefinite because of the limit of usefulness of the rolling-ball viscometer in low-viscosity regions.

    Viscosity of nitrous oxide in the critical region (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 603-626 
    Details
    ISSN: 1572-9567
    Keywords: critical anomaly ; mode-coupling theory ; nitrous oxide ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The gaseous viscosity of nitrous oxide (N2O) was measured in the critical region. The experimental temperature range was between 309.650 and 318.150 K and the pressure range was up to 9.6 MPa. The measurements were obtained with an oscillating-disk viscometer, combined with local determination of the density at the position of the oscillating disk, and they have an estimated accuracy of 0.6 % for viscosity and 0.5 % for gas density. The viscosity of N2O exhibits an anomalous increase near the critical point. The anomalous increase in viscosity was analyzed with the viscosity equation proposed by Basu and Sengers.

    Notes: Abstract Measurements of saturated liquid viscosities and densities were performed on environmentally acceptable hydrochlorofluorocarbons (HCFCs), CH3CCl2F (HCFC-141b), CH3CClF2 (HCFC-142b; only for viscosity), CF3CF2CHCl2 (HCFC-225ca), and CClF2CF2CHClF (HCFC-225cb), using a capillary viscometer and a glass pycnometer in the temperature range from 273 to 353 K. The uncertainty in the measurement of viscosity is estimated to be 5% based on the comparison of the present data with those in the literature for HCFC-141b. An equation is given to represent our saturated liquid viscosity data as a function of temperature.
