Trends and Properties of Human Cerebral Cortex: Correlations with Cortical Myelin Content (2013, positive): “…in sensitivity to cortical areal boundaries across methods. enable interested investigators to model B1 − and B1 + fields more precisely, the HCP is acquiring scans for mapping these intensity bias fields (head and body coil images with the same sequence for B1 − and AFI for B1 + (Yarnykh, 2007)).”
What are normal relaxation times of tissues at 3 T? (2017, methodology): “The B1-map values are computed from the ratio of the signal of the two TRs acquisitions for every voxel [31].”
Using high-resolution quantitative mapping of R1 as an index of cortical myelination (2014, positive): “The actual flip-angle imaging (AFI) method proposed by Yarnykh (2007) is an attractive alternative since the independence of the resulting B1+ maps on R1 allows the use of short TRs and therefore short acquisitions.”
In vivo histology of the myelin g-ratio with magnetic resonance imaging (2015, methodology): “For the diffusion acquisition, five signal averages of 100 diffusion encoding directions with both b = 1000 s/mm(2) and b = 2450 s/mm(2), as well as two b = 0 s/mm(2) images were acquired using a 2D twice-refocused balanced echo (Yarnykh, 2007) single shot spin-echo echo-planar imaging (SE-EPI) sequ”
Multi-Parametric Neuroimaging Reproducibility: A 3T Resource Study (2010, methodology): “B1 sequence Here, we use the Actual Flip-Angle Imaging (AFI) to produces B1 maps using a single-scan pulsed steady-state acquisition, which is insensitive to T1, T2, T2*, spin density, coil reception profile, and flow or motion artifacts (Yarnykh, 2007).”
The Minimal Preprocessing Pipelines for the Human Connectome Project (2013, positive): “The B 1 + transmit field can be calculated from an actual flip-angle imaging (AFI) acquisition (Yarnykh, 2007) with TR1/TR2 = 20/120 ms (target flip angle = 50°).”
Determination of Electric Conductivity and Local SAR Via B1 Mapping (2009, methodology): “(a) Short-TR FFE image for the B1 mapping using the AFI technique [31].”
Fast 3D Magnetic Resonance Fingerprinting (MRF) For a Whole Brain Coverage (2017, neutral): “The two common ways to correct for the FA error are to premeasure the B1 or FA map (3,29,30), or to quantify B1 at the same time as the tissue parameters (28,31,32).”
Fragment Length of Circulating Tumor DNA (2016, methodology): “Pre-contrast B1 maps using the actual flip angle imaging method [32] were acquired with the following parameters: TR1/TR2/TE = 25/ 125/6.”
