CT pulmonary angiography is a medical imaging technique that uses computed tomography (CT) to visualize the blood vessels in the lungs, particularly the pulmonary arteries. This procedure is primarily utilized to diagnose conditions such as pulmonary embolism, which is the blockage of a pulmonary artery often caused by blood clots. The images produced provide critical information about the vascular structures of the lungs, enabling healthcare professionals to assess various pulmonary vascular diseases effectively.
