    Gradient recalled echo MR imaging of superior sagittal sinus occlusion (1989)
    Springer
    Neuroradiology 31 (1989), S. 134-136 
    Details
    ISSN: 1432-1920
    Keywords: Gradient recalled echo ; MRI ; Sinus occlusion
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary With T1-weighted gradient recalled echo (GRE) MR images and flow compensation, we studied the superior sagittal sinus in 3 normal volunteers and 3 patients with sinus occlusion. In these images, sites of patency of the superior sagittal sinus were identified due to the high signal intensity of the normal sinus. Tumor invading the sinus was nearly isointense with cerebral gray matter. T1-weighted GRE imaging proves to be an effective technique to evaluate sinus blood flow.

    T1, T2 and proton density measurements in the grading of cerebral gliomas (1993)

    Notes: Abstract The possibility that cerebral tumours may be graded by measuring T1 or T2 with magnetic resonance (MR) imaging was studied. A consecutive series of patients with subsequently verified gliomas was enrolled, and studied with MR. Patients who had prior surgical, chemotherapeutic or steroid treatment were excluded. Single slice multiple saturation recovery and multiple spin echo techniques were used to measure T1, T2 and proton density in the tumour. In 33 patients with cerebral gliomas there were 5 grade I, 12 grade II, 7 grade III and 9 grade IV. T1 and T2 values tended to be smaller in grade I gliomas than in grades II, III and IV gliomas. Relaxation parameters overlapped considerably in tumours with different grades. Proton density values did not show much change between different grades of gliomas. Relaxation parameters cannot be used to determine tumour grade reliably.

    Description / Table of Contents: Zusammenfassung Die Ergebnisse therapeutischer Massnahmen bei Lebermetastasen können nur unter Berücksichtigung des Spontanverlaufes dieser Erkrankung beurteilt werden. Dazu bedarf es einer Prognoseberechnung therapeutisch relevanter Gruppen. Für Patienten, die nach heute gültigen Kriterien für eine Therapie in Frage kommen, fand sich eine mediane Überlebenszeit von 11 Monaten und eine drei-Jahres-Überlebensrate von 17%. Hieran wird die Effektivität therapeutischer Verfahren zu messen sein.
    Notes: Summary The therapeutic results in treatment of liver metastasis can only be judged with regard to the natural history of the disease for which the prognosis of therapeutically relevant groups must be evaluated. The median survival time was 11 months and the probability of 3-year survival 17% for patients who today are potential candidates for the various therapeutic procedures available. These results must be taken into consideration as a measure of the effectiveness of the therapies applied.

    Description / Table of Contents: Zusammenfassung Bei 21 Patienten fand sich nach Resektion von Lungenmetastasen und befallener Brustwand unabhängig von der Grösse der Brustwandinfiltration eine mediane Überlebenszeit von 11 Monaten. Nur 1 Patient mit Hodenteratom-Metastasen überlebte 5 Jahre und ist tumorfrei. Die 30-Tage-Letalität betrug 0%. Hauptindikation sind Komplikationen, wie Exulceration und Schmerz. Trotz schlechter Prognose kann eine Lebensverlängerung bei verbesserter Lebensqualität erreicht werden. In seltenen Fällen ist nach Tumorreduktion bei chemotherapiesensiblen Tumoren eine Heilung möglich.
    Notes: Summary In 21 patients after combined chest wall and lung metastasis resection a median survival time of 11 months was found independent of the degree of the chest wall infiltration. Only 1 patient with metastasis from a testicular teratoma survived 5 years and is tumor free. There was no 30-day-lethality. The main indications are complications such as exulceration and pain. In spite of the poor prognosis a prolongation of survival time with improved quality of life may be achieved. In rare cases cure is possible by combined tumor reductive surgery and chemotherapy.

    Description / Table of Contents: Thermal Behaviour of Li3MnO4. II. α- and β-Li2MnO3By thermal decomposition of Li3MnO4 we obtained two new forms of Li2MnO3: α-Li2MnO3 crystallizes due to Guinier-Simon photographs cubic face-centered with a = 4.092 Å, β-Li2MnO3 hexagonal with a = 4,93, c = 14.24 Å, c/a = 2.89. α-Li2MnO3 is paramagnetic with μ = 3,82 B.M.

    Description / Table of Contents: Notice on the Magnetic Behaviour of Li3CrO4Li3CrO4, a smaragd green powder, is due to powder photographs (Guinier-Simon-technique) isotypic with orthorhombic HT—Li3PO4, a = 6.309, b = 10.851, c = 4.952 Å, Z = 4. Between 298 and 10K the Curie-Weiss-Law is obeyed with μ=1.60 B.M. and Θ=+10 K. Below 5 K ferromagnetism is observed. ESR measurements at 4.2 K and more pronounced at 1.8 K show anisotropy of the ligand field.
    Notes: Li3CrO4, ein smaragdgrünes Pulver, ist nach Guinier-Simon-Aufnahmen isotyp mit HT-Li3PO4, a = 6,309 Å, b = 10,851 Å, c = 4,952 Å, Z = 4. Zwischen 298 und 10 K wird das Curie-Weisssche Gesetz mit μ=1,60 B.M., Θ=+10K befolgt. Unterhalb von 5 K tritt überraschend Ferromagnetismus auf. ESR-Messungen bei 4,2 K und ausgeprägter bei 1,8 K zeigen eine Anisotropie des Ligandenfeldes.

    Description / Table of Contents: Hexachloroniobates(V), -tantalates(V), and -antimonates(V): AIMVCl6 (AI = Na, K, Tl, NH4, Rb, Cs; MV = Nb, Ta, Sb)Hexachlorometallates(V) AINbCl6, AITaCl6, and AISbCl6 (AI = Na, K, Tl, NH4, Rb, Cs) have been prepared by reaction of the binary components at 280°C (niobates), 300°C (tantalates), and in POCl3 solution (antimonates), respectively, and were investigated by Raman spectroscopy and X-rays with the Guinier-Simon technique. The low-temperature modifications of AIMCl6 (AI = K, Tl, NH4, Rb, Cs with the exception of KNbCl6) are isotypic to CsWCl6 with isolated octahedra ∞0[MCl6]. The high-temperature modifications crystallize cubic face-centered. Raman spectra of KNbCl6, NaNbCl6 and NaTaCl6 support a formulation like e. g. K2[Nb2Cl10]Cl2 with isolated edgesharing bioctahedra ∞0[(NbCl4/1tCl2/2e)2].
    Notes: Die Chloride AINbCl6, AITaCl6 und AISbCl6 (AI = Na, K, Tl, NH4, Rb, Cs) werden aus den binären Komponenten bei 280°C (Niobate), 300°C (Tantalate) bzw. aus POCl3-Lösung (Antimonate) dargestellt und ramanspektroskopisch bzw. röntgenographisch (Guinier-Simon-Technik)untersucht. Die Tieftemperaturformen von AIMCl6 (AI = K, Tl, NH4, Rb, Cs, außer KNbCl6) sind mit CsWCl6 isotyp (isolierte Oktaeder ∞0[MCl6]). Die Hochtemperaturformen kristallisieren kubisch-flächenzentriert. Ramanspektren von KNbCl6, NaNbCl6 und NaTaCl6 sprechen für eine Formulierung gemäß z. B. K2[Nb2Cl10]Cl2 mit „isolierten“, kantenverknüpften Doppeloktaedern ∞0[(NbCl4/1tCl2/2k)2].
