    Notizen: Abstract  Objective. To evaluate the MRI appearances in insufficiency fractures. Design. A retrospective analysis of spin echo MR images with gadolinium-enhancement was undertaken with the emphasis on the signal change and the shape of the fracture gap and the adjacent bone marrow. Patients. Five elderly women who had ischiopubic insufficiency fractures (pubis, 4; ischium 1) underwent MRI to exclude the possibility of pathologic fractures. Results and conclusions. In no case was contrast enhancement noted at the fracture gap or the adjacent bone marrow, but a cleft-life, elongated bright signal area suggesting “fluid collection” was noted within the fracture gap. Absence of contrast enhancement and “fluid collection” at the fracture gap might suggest nonunion of a fracture, which is additional information provided only by MRI.

    The anterior choroidal artery syndrome (1994)
    Springer
    Neuroradiology 36 (1994), S. 340-345

    Schlagwort(e): Infarcts, anterior choroidal artery ; CT ; MRI ; Angiography

    Thema: Medizin
    Notizen: 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.

    Notizen: Abstract Germplasm conservation of the tropical forest trees, Cedrela odorata L., Guazuma crinita Mart., and Jacaranda mimosaefolia D. Don., at above-freezing temperatures following alginate-bead encapsulation was attempted. Shoot tips excised from in vitro plantlets were encapsulated in calcium-alginate beads and stored on different substrates at 12, 20, and 25°C. Percent viability when encapsulated shoot tips were stored on substrate containing only water solidified with 1% (wt/vol) agar was 80% after 12 months at 12°C for C. odorata, 90% after 12 months at 25°C for G. crinita, and 70% after 6 months at 20°C for J. mimosaefolia.
