What is CT Angio- Pulmonary Embolism?
Doctors find CT (computed tomography) Angio – Pulmonary Embolism 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.

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.
