CT Scan Pulmonary Embolism Angiography (CTA)
Understanding CT Scan Pulmonary Embolism Angiography (CTA)
What is 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.
