Super High Contrast USPIO-Enhanced Cerebrovascular Angiography Using Ultrashort Time-to-Echo MRI

Figure 1

QUTE-CE provides a high vascular signal and contrast with low heterogeneity. (a) Typical raw axial and sagittal slices of Quantitative Ultrashort Time-to-Echo Contrast-Enhanced MR angiography (QUTE-CE MRA), ferumoxytol contrast-enhanced Magnetization Prepared RApid Gradient Echo (Fe MPRAGE), and time-of-flight (TOF) MRA. All slices are taken from the same participant after alignment and coregistration, allowing visual comparison of the same anatomical structures in each modality. QUTE-CE MRA captures more vessels than the other techniques. (b) Cropped views of an exemplary luminal cross-section from each technique.
