CT Scan Pulmonary Embolism Angiography (CTA)

Doctors find the CT Scan Pulmonary Embolism Angiography (CTA) an excellent imaging method for the timely detection of a pulmonary embolism. It occurs when a blood clot travels through your bloodstream and lodges in a blood vessel in your lungs. An embolism may cause symptoms like chest pain, shortness of breath, dizziness, swelling in your legs. Delay in treatment can be life-threatening. Once detected, doctors initiate treatment to prevent further complications.

During the scan, your doctor injects a special dye through your vein, which provides better images of the blood vessels in your chest and lungs. Rotating x-ray beams take images that confirm the presence of a clot. Let your doctor know if you have had any recent surgery, are allergic to contrast material, or are pregnant.
