Fig. 6
a–g A 63-year-old man with a prolonged history of Takayasu arteritis. MDCTA axial images of the chest at the level of the main and left pulmonary artery (a), right pulmonary artery (b, c) and right upper lobe demonstrate substantial thickening of the pulmonary arterial wall, especially pronounced at the level of the right pulmonary artery with almost complete occlusion of the right upper lobe branch and pulmonary infarcts (d) (arrows). T1-weighted (e), T2-weighted (f) and GD-enhanced (g) MRI images emphasise the same findings as well as substantial wall oedema seen as bright signal on T2-weighted images (f) (arrows)
