Resumo(s)
Objectives: To assess the feasibility of
performing pulmonary angiography using
MRI with contrast enhancement in patients
with pulmonary vascular disease.
Methods: We present our experience in ten
individuals, two controls and eight patients
who underwent the exam after injection of a
gadolinium-based contrast agent on a 1 Tesla
MR scanner using a time-of-flight sequence
and breath-holding during injection of
contrast.
Results: Pathology in the main pulmonary
artery and its major branches was detected
easily while resolution at the segmental and
subsegmental levels was inadequate.
Conclusion: Contrast-enhanced magnetic
resonance pulmonary angiography is feasible
on a 1 Tesla MR scanner for the study of
pathology of the main pulmonary artery and
its major branches, like massive pulmonary
embolism. However its ability to detect and
define distal vessel pathology as found in
chronic thromboembolic pulmonary
hypertension and small pulmonary emboli is
limited.
