  • Title: [Semiotics of lesions of the cerebral venous collectors on application of noninvasive techniques of x-ray diagnosis].
    Author: Semenov S, Abalmasov V.
    Journal: Vestn Rentgenol Radiol; 2001; (5):9-15. PubMed ID: 11767504.
    Abstract:
    The study included application of a complex of the noninvasive diagnostic techniques such as MR tomography, MR venography, duplex scanning of the internal jugular veins, and transcranial Doppler sonography. The authors provide a detailed description of the semiotics of the MR signs of cerebral venous collector lesion in patients with thrombosis, extravasal compression, aneurysms, and developmental anomalies. Present the quantitative ultrasound parameters of hemodynamics in the efferent vessels of the brain accessible to inspections describe the effect of spontaneous echo-opacification in the internal jugular veins, which is assumed to be a predictor of thrombosis. Intravenous injection of magnevist resulted in an appreciable refinement of visualization of small dural sinuses at MR venography thereby allowing for the diagnosis of their thrombosis. It is suggested that the use of the entire complex of the x-ray modalities under consideration may lead to a more complete and noninvasive evaluation of the nature of cerebral venous insufficiency and of the degree of hemodynamic significance. Moreover, this will make it possible to outline approaches to therapeutic or surgical correction of the disease.
