Medientyp: E-Artikel Titel: Brain perfusion territory imaging applying oblique‐plane arterial spin labeling with a standard send/receive head coil Beteiligte: Werner, Richard; Alfke, Karsten; Schaeffter, Tobias; Nabavi, Arya; Mehdorn, H. Maximilian; Jansen, Olav Erschienen: Wiley, 2004 Erschienen in: Magnetic Resonance in Medicine Sprache: Englisch DOI: 10.1002/mrm.20253 ISSN: 0740-3194; 1522-2594 Schlagwörter: Radiology, Nuclear Medicine and imaging Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>A new method for the selective spin labeling of left‐ or right‐sided supplying arteries of the brain without the need for additional RF coils is demonstrated. A clinical 1.5 T scanner was used. The spatial selectivity of the labeling process is based on the limited coverage of the excitation field of a standard send/receive head coil together with an oblique positioning of the labeling plane. A computer simulation was used to optimize key labeling parameters under the condition of laminar flow. The validity of the computer model results was confirmed by MRI measurements with a flow model. For human studies, a double‐inversion continuous arterial spin labeling (CASL) sequence was modified to allow for arbitrary positioning of the labeling plane. The obtained perfusion‐weighted images showed a clear delineation of the perfusion territories of the selected arteries in the anterior circulation of the brain and good gray/white matter contrast.
