    Imaging of huge lingual thyroid gland with goitre (1998)
    Springer
    Neuroradiology 40 (1998), S. 335-337 
    Details
    ISSN: 1432-1920
    Keywords: Key words Thyroid ; lingual ; Goitre ; Computed tomography ; Magnetic resonance imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We present the CT and MRI findings in a 75-year-old woman with a huge pathologically proven lingual thyroid which underwent goitrous degeneration. CT and MRI showed a midline, tongue-based, exophytic mass with areas of necrosis and heterogeneous contrast enhancement, as seen in large goitres in the normal thyroid gland.

    The MRI signs of spinal arachnoid diverticula (1997)
    Springer
    Neuroradiology 39 (1997), S. 446-449 
    Details
    ISSN: 1432-1920
    Keywords: Key words Arachnoid diverticula ; Spine ; Magnetic resonance imaging ; Gadolinium

    Topics: Medicine
    Notes: Abstract Our goal was to find MRI signs of use for identifying a spinal arachnoid diverticulum. Three cases of spinal arachnoid diverticula, one extradural and two intradural, were examined on a 1.5 T imager. There was obvious mass effect on the adjacent structures in one case and increased signal intensity in the diverticulum on proton density- and T2-weighted images in two cases. Signal changes due to turbulent movement of the spinal fluid inside the diverticula were seen in all cases on sagittal fast spin-echo (FSE) proton density- and T2-weighted images; it was difficult to tell whether these signal changes imply a communication or are simply FSE artefacts. On contrast-enhanced studies, all cases showed partial enhancement inside the diverticula. There thus are four signs of diverticula: mass effect, the increased signal, signal void sign and partial enhancement; the last of these, the most reliable, has never been reported before.

    Central gadolinium enhancement of an acute spontaneous spinal epidural haematoma (1996)
    Springer
    Neuroradiology 38 (1996), S. S114 
    Details
    ISSN: 1432-1920
    Keywords: Key words Spine ; haemorrhage ; Gadolinium ; Magnetic resonance imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Spontaneous spinal epidural haematoma (SSEH) is uncommon, but central gadolinium (Gd) enhancement of the haematoma is even rarer. To our knowledge, only one case has been reported, but no explanation was given concerning the mechanism of this enhancement. We present a case of SSEH with unusual central Gd enhancement which we believe is due to oozing from the injured posterior internal venous plexuses. Therefore, although rare, central Gd enhancement of an epidural mass should not rule out the possibility of a haematoma.

    Radiation-induced crosslinking: II. Effect on the crystalline and amorphous densities of polyethylene (1991)
    Springer
    Colloid & polymer science 269 (1991), S. 469-476

    ISSN: 1435-1536
    Keywords: Crosslinking ; radiation ; polyethylene ; density ; crystallinity ; d-spacings ; phase densities ; crosslink locations and mechanisms ; defects ; lateral grain boundaries

    Notes: Abstract Small-angle x-ray scattering (SAXS) was used to determine the structural changes in polyethylene induced by radiation. The changes in densities of the crystalline and amorphous phases, ρ c and ρ a , were calculated after direct determination of the mean square density fluctuation 〈η2〉. ρ a increases with increasing radiation dose for both linear and branched polyethylene. This accounts for the serious discrepancy between crystallinities determined from wide-angle x-ray scattering and density measurements. This study confirms our previous proposal that crosslinks occur primarily in the noncrystalline phase, most likely at the defects in the lateral grain boundary regions.
