      abstract     = {ObjectivesTo apply the MB (multiband) excitation and
                      blipped-CAIPI (blipped-controlled aliasing in parallel
                      imaging) techniques in a spin and gradient-echo (SAGE) EPI
                      sequence to improve the slice coverage for vessel
                      architecture imaging (VAI).Materials and methodsBoth MB
                      excitation and blipped-CAIPI with in-plane parallel imaging
                      were incorporated into a gradient-echo (GE)/spin-echo (SE)
                      EPI sequence for simultaneous tracking of the dynamic MR
                      signal changes in both GE and SE contrasts after the
                      injection of contrast agent. MB and singleband (SB)
                      excitation were compared using a 20-channel head coil at 3
                      Tesla, and high-resolution MB VAI could be performed in 32
                      glioma patients.ResultsWhole-brain covered high resolution
                      VAI can be achieved after applying multiband excitation with
                      a factor of 2 and in-plane parallel imaging with a factor of
                      3. The quality of the images resulting from MB acceleration
                      was comparable to those from the SB method: images were
                      reconstructed without any loss of spatial resolution or
                      severe distortions. In addition, MB and SB signal-to-noise
                      ratios (SNR) were similar. A relative low g-factor induced
                      from the MB acceleration method was achieved after using a
                      blipped-CAIPI technique (1.35 for GE and 1.33 for SE
                      imaging). Performing quantitative VAI, we found that, among
                      all VAI parametric maps, microvessel type indicator (MTI),
                      distance map (I) and vascular-induced bolus peak-time shift
                      (VIPS) were highly correlated. Likewise, VAI parametric maps
                      of slope, slope length and short axis were highly
                      correlated.ConclusionsMultiband accelerated SAGE
                      successfully doubles the number of readout slices in the
                      same measurement time when compared to conventional readout
                      sequences. The corresponding VAI parametric maps provide
                      insights into the complexity and heterogeneity of vascular
                      changes in glioma.},
