Magnetic Resonance Angiography Using Fresh Blood Imaging in Oral and Maxillofacial Regions
Figure 6
MRA by 3D-FBI in the oral and maxillofacial regions of a 49-year-old healthy volunteer. MRA using 3D-FBI can distinguish between arteries (a) and veins (b) without the use of contrast medium. (a) Images acquired during diastole. The carotid artery, internal jugular vein, maxillary artery, maxillary vein, facial artery, facial vein, lingual artery, and lingual vein are visualized. Acquisition time was 3 minutes and 36 seconds. (b) Images acquired during systole. The internal jugular vein (arrow), maxillary vein (arrowhead), facial vein (black arrowhead), and lingual vein (gray arrowhead) are depicted. Acquisition time was 3 minutes and 36 seconds. (c) The subtraction image of the systolic image (b) from the diastolic image (a) that depicts the carotid (arrow), maxillary (arrowhead), facial (black arrowhead), and lingual arteries (gray arrowhead).
