      abstract     = {Collateral networks in Moyamoya angiopathy have a complex
                      angioarchitecture difficult to comprehend on conventional
                      examinations. This study aimed to evaluate morphologic
                      patterns and the delineation of deeply seated collateral
                      networks using ultra-high-field MRA in comparison with
                      conventional DSA.Fifteen white patients with Moyamoya
                      angiopathy were investigated in this prospective trial.
                      Sequences acquired at 7T were TOF-MRA with 0.22 × 0.22 ×
                      0.41 mm3 resolution and MPRAGE with 0.7 × 0.7 × 0.7 mm3
                      resolution. Four raters evaluated the presence of deeply
                      seated collateral networks and image quality in a consensus
                      reading of DSA, TOF-MRA, and MPRAGE using a 5-point scale in
                      axial source images and maximum intensity projections.
                      Delineation of deeply seated collateral networks by
                      different imaging modalities was compared by means of the
                      McNemar test, whereas image quality was compared using the
                      Wilcoxon signed-rank test.The relevant deeply seated
                      collateral networks were classified into 2 categories and 6
                      pathways. A total of 100 collateral networks were detected
                      on DSA; 106, on TOF-MRA; and 73, on MPRAGE. Delineation of
                      deeply seated collateral networks was comparable between
                      TOF-MRA and DSA (P = .25); however, both were better than
                      MPRAGE (P < .001).This study demonstrates excellent
                      delineation of 6 distinct deeply seated collateral network
                      pathways in Moyamoya angiopathy in white adults using 7T
                      TOF-MRA, comparable to DSA.},
