MR-tomographische Darstellung von Liquorpulsationen

Abstract: With ECG-gated FLASH-sequences motion of cerebrospinal fluid (CSF) is demonstrated in axial slices of the zervikal vertebral column. The course of the movement is dissolved by signal enhancement of flowing structures in magnitude images and by velocity-dependent phases. It is shown with both methods, that the oscillation of the CSF within the cardiac cycle is superimposed by a directed movement, with is cranial directed in the lateral cervical subarachnoidal spaces and caudal in the ventral subarachnoidal spac… Show more

“…noch keine zuverlässige Bestimmung von Normbereichen, ähnlich wie auch für die anderen Abschnitte der ZSLD keine definierten Daten vorliegen, die eine zuverlässige Abgrenzung des Normalen vom Pathologischen erlauben [12,13,20,21]. Ursache hierfür sind zum einen die heterogene Zusammensetzung vieler Kollektive sowie kleine Fallzahlen bei groûer interindividueller Schwankungsbreite der ZSLD.…”

“…Methoden: 68 gesunde Probanden und 4 Patienten wurden in drei Phasen untersucht. Phase I: 19 Probanden zur Sequenzoptimierung mit je 4 Messungen (4,8,12, 16 cm/s Flusssensitivität). Phase II: 49 Probanden wurden mit der optimierten Phasenkontrastsequenz untersucht.…”
