The cost of a CTA (CT angiography) is about 1500 dollars, and there may be price differences due to regional and hospital differences. Common CTA exams include head and neck CTA, coronary CTA, and bilateral lower extremity CTA. CTA exams require a contrast agent, and the price of a typical contrast agent (e.g., iopromide injection) is around $300, and with the post-processing of the image costing around $1,200, the total will be around $1,500. CTA can play a screening role, such as cranial CTA can screen patients for aneurysms and intracranial arterial stenosis, and coronary CTA can check patients for coronary artery stenosis. Please consult your local hospital for pricing.
