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

Figure 4

The technique provides more detailed vascular images than time-of-flight (TOF). Maximum intensity projection (MIP) (a) Quantitative Ultrashort Time-to-Echo Contrast-Enhanced (QUTE-CE) and (b) TOF MR angiography image intensities demonstrating the complete contrast enhancement of the vasculature in QUTE-CE MR angiography. QUTE-CE MR angiography captures all vasculature available in the TOF and much more of the cerebral vascular system in approximately the same imaging time. This detail can be examined by subsectioning the QUTE-CE field-of-view into slabs, labeled in the left-right MIP of the full field-of-view and presented as S-I projections of each slab.
