MR Angiography of the Head/Neck Vascular System in Mice on a Clinical MRI System

Figure 2

Area measurements of the aorta, brachiocephalic artery, and carotid artery on non-contrast-enhanced and contrast-enhanced MR angiographies. The diagram presents the luminal area measurements of the aorta, brachiocephalic artery, and carotid artery in mm². Luminal area measurements based on the non-contrast-enhanced MR angiography (TOF) demonstrated significantly higher area measurements for the carotid artery (0.55 ± 0.14 mm²; ), the brachiocephalic artery (1.14 ± 0.29 mm²; ), and the aorta (2.63 ± 0.42 mm²; ) compared to the contrast-enhanced MR angiography (GdT). Luminal area measurements for the contrast-enhanced MR angiography following the administration of gadofosveset trisodium were as follows: carotid artery (0.31 ± 0.07 mm²), brachiocephalic artery (0.78 ± 0.26 mm²), and aorta (2.25 ± 0.61 mm²).
