85 Comparison of 3T Intracranial Vessel Wall MRI Sequences 4 In addition, in 10 other subjects precontrast and postcontrast images were acquired of our earlier published and clinically used variant 3, which had good CSF suppression, and the fastest, variant 7 (consecutively variant 3 and 7 in 8 subjects and consecutively variant 7 and 3 in 2 subjects). We have chosen to compare the fastest, variant 7, with our clinical used variant for clinical and practical purposes. Before acquisition of the postcontrast sequences, a gadolinium-containing contrast agent (gadobutrol, Gadovist 1.0mmol/mL, Bayer Schering Pharma, Berlin, Germany), was administered intravenously. The total scan session took 45 minutes and included, consecutively, the preparation phase with the survey scans, TOF- MRA, precontrast vessel wall sequences, postcontrast DWI, postcontrast vessel wall sequences (acquired ~20 min after the precontrast vessel wall sequence) including noise images; and finally, a postcontrast T2-FLAIR sequence.
