Nonangiographic imaging of the pulmonary arteries: CT and MR.
Computed tomography (CT) has provided a imaging modality by which the central pulmonary arteries can be studied noninvasively. CT provides cross-sectional images which accurately depict the pulmonary arteries and adjacent structures. Magnetic resonance (MR) imaging with its ability to image vessels without contrast media provides a potential truly noninvasive means of examining the pulmonary arteries. These modalities are well suited to evaluate pathology involving the central pulmonary arteries. Normal CT and MR anatomy is illustrated and discussed. The clinical presentation and appearance of pathological processes involving the pulmonary arteries are described.
