Answer

Although conventional angiography has historically been the standard for diagnosis and evaluation of the extent of disease, computed tomography and magnetic resonance techniques have gained favor for initial evaluation, as they are less invasive than standard angiography and allow diagnosis of Takayasu arteritis earlier in the disease course. [33, 34] Ultrasonography is useful for carotid assessment, while 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is useful for patients with no vascular signs or symptoms, fever of unknown origin, or an unexplained acute-phase response. (See the images below.) [35, 34, 33]
