Experts agree that an angiogram can help your doctor diagnose a heart condition so you get the best treatment for you. When used in conjunction with validated clinical decision tools like modified Wells criteria, CT-angiography is highly sensitive (good at detecting PE when it's there and ruling it out when it's not) and specific (generating few false-positive results).
