1 High-resolution MR imaging, CTA, and sonography of the left carotid artery of a 77-year-old man.
High-resolution MR imaging, CTA, and sonography of the left carotid artery of a 77-year-old man. Ulcerations (yellow arrow) are shown clearly on CE-MRA (A) and pre- and postcontrast black-blood T1-weighted (D and E) images; however, they were missed on TOF-MRA (B). The calcification on CTA (white arrow, C) causes difficulty when observing the ulceration. Doppler sonography (F) shows no ulceration in the internal carotid artery. J. Yuan et al.
