Therefore, the contrast-enhanced 3D CISS sequences appeared to be the most appropriate sequence for evaluating the trigeminal ganglion, whereas contrast-enhanced 3D TOF sequences were most appropriate for depicting the cranial and foraminal segments of V1, V2 and V3. This could have been achieved by imaging the specimens in whom cryomicrotomic sections were later obtained. All patients gave their informed consent.All imaging was performed by using a 1.5-T system (Magnetom Vision; Siemens, Erlangen, Germany) with the regular quadrature head coil. The distance was determined from the most anterior point of the convex surface to the concave inside of the ganglion.
Die Nervenzellkörperansammlungen treten als Verdickungen in Erscheinung und werden aus diesem Grund häufig auch Nervenknoten genannt. Sensory root (Identification of these structures was positive when all three elements were identified: the upper and lower lips of the ganglion and the sinus ganglii. The patients agreed to undergo imaging with extra (enhanced) 3D CISS and 3D time-of-flight (TOF) MR angiographic (MRA) sequences.
Dabei öffnet er den Schädelknochen hinter dem Ohr, um an den Trigeminusnerv zu gelangen. Dort platziert er ein kleines Stück Kunststoff, welches als eine Art Puffer fungiert, sodass das Gefäß nicht länger auf den Nerv drückt.
Enhanced 3D CISS images also depicted the trigeminal branches V1 (91–100%), V2 (84–93%), and V3 (80–100%) but not as well as enhanced 3D TOF images (97.6–100% for all divisions). The typical semilunar form of the trigeminal ganglion consisted of the convex anterior surface and the concave posterior surface (the sinus ganglii). Complete MR imaging evaluation of the trigeminal ganglion and roots is best performed using both contrast-enhanced 3D CISS and contrast-enhanced 3D TOF MRA sequences.Thank you for your interest in spreading the word on American Journal of Neuroradiology.NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Bei Patienten mit schwerwiegenden Begleiterkrankungen und hohem Narkoserisiko wird die Injektion von Glycerin in das Ganglion Gasseri (einem Nervenknoten an der Schädelbasis) durchgeführt. The contrast-enhanced 3D CISS sequence also provided excellent depiction of the three main trigeminal branches (V1, V2, and V3), although the contrast-enhanced 3D TOF sequence was better for displaying these nerves.The Meckel cave is an enclosure formed by two layers of dura: an internal layer of dura propria and an external layer of intracranial periosteum (The trigeminal ganglion is a thin crescent-shaped (semilunar) structure (The pars triangularis is the fan-shaped expansion of sensory rootlets that anastomose with each other and that extend posteriorly from the sinus ganglii (Most previous studies of the trigeminal ganglion were performed using contrast-enhanced T1-weighted sequences (The 3D CISS sequence is a high-spatial-resolution, refocused gradient-echo MR imaging sequence that is flow compensated.
Das Ganglion trigeminale ist ein innerhalb der Schädelhöhle gelegenes, sensibles Ganglion, das die Teilungsstelle des Nervus trigeminus darstellt.. 2 Topografie.
