OBJECTIVE. Pulmonary artery involvement in Takayasu's arteritis is suggesti
ve of the disease. Our aim was to use electron beam CT to study pulmonary a
rtery changes in patients with Takayasu's arteritis.
CONCLUSION. Diffuse wall thickening and dilatation or stenosis were signifi
cantly more frequent on CT in patients with Takayasu's arteritis than in th
e control subjects. Knowledge of these findings may be of value when assess
ing pulmonary artery involvement and thus may be helpful for the diagnosis
of Takayasu's arteritis.
