Magnetic Resonance Angiography Using Fresh Blood Imaging in Oral and Maxillofacial Regions
Figure 3
MRA using 3D-PC (a) and 3D-FBI (b) in the oral and maxillofacial regions of a healthy 48-year-old volunteer. MRA using 3D-FBI provides better 3D visualization of the vasculature of thin blood vessels, including the lingual and facial arteries, than 3D-PC-MRA. (a) On MRA using 3D-PC, the external (arrow) and internal carotid (black arrow), maxillary (arrowhead), and facial arteries (black arrowhead) are shown. Acquisition time was 10 minutes and 15 seconds. (b) On MRA using 3D-FBI, the external (arrow) and internal carotid (black arrow) and other peripheral vessels are shown. The maxillary (arrowhead), facial (black arrowhead), lingual (gray arrowhead), and further peripheral arteries are more precisely shown than in Figure 3(a) in the same subject. Acquisition time was 4 minutes and 5 seconds.
