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

Figure 2

Signal-to-noise ratio (SNR), intraluminal signal heterogeneity (ISH), and contrast-to-noise ratio (CNR) for participants with directly comparable scans. Quantitative Ultrashort Time-to-Echo Contrast-Enhanced MR angiography (QUTE-CE MRA) provides higher blood SNR and blood-tissue CNR than the time-of-flight (TOF) MRA or T1-weighted ferumoxytol contrast-enhanced Magnetization Prepared RApid Gradient Echo (Fe MPRAGE) in every participant while maintaining lower ISH. Participants are excluded in cases where scans were significantly motion-degraded.
