Q. Define Pulmonary angiography?
Pulmonary angiography is the angiographic opacification of the main and pulmonary artery and its branches. By radiographic techniques, it is possible to picturize up to seventh order pulmonary arteries. Newer imaging modalities like CT and MR angiography are fast emerging as superior alternatives to angiography but there is a need to hold on to this modality in view of its therapeutic potential.
