3T transversal contrast fat-suppressed T1-weighted SE image acquired with the large FOV that covers the entire cranial circumference. 3T transversal contrast fat-suppressed T1-weighted SE image acquired with the large FOV that covers the entire cranial circumference. Enlargements of the temporal branch of the superficial temporal arteries (A and B) and of the superficial occipital arteries (C and D) demonstrate the cranial involvement pattern. Mural thickening and inflammatory changes are depicted in the left temporal artery (enlargement B, 0.7-mm mural thickness, rated as “3”) and occipital artery (enlargement D, 0.7-mm mural thickness, rated as “3”), whereas the right-sided arteries display no signs of mural inflammation (enlargements A and C, 0.2-mm mural thickness, both rated as “0”). Temporal artery biopsy validates GCA in this patient. T.A. Bley et al. AJNR Am J Neuroradiol 2007;28:1722-1727 ©2007 by American Society of Neuroradiology
