Q. Is CT angiography better than conventional angiography?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Yes, CT angiography (CTA) has been increasingly used in the diagnosis and management of cardiovascular disease due to its advantages over conventional angiography. CTA is less invasive than conventional angiography, does not require injection of contrast medium into the circulatory system, can provide better resolution for vascular imaging, and can easily capture three-dimensional data that can be manipulated to create detailed models of blood flow. Moreover, CTA has a much lower radiation dose compared to conventional angiography.
In addition to being less risky technically and more accurate diagnostically, CTA offers several other benefits when compared to traditional methods. For example:
• It reduces hospital stays since it requires only one visit as opposed to two with conventional angiology;
• It allows physicians to diagnose non-surgical conditions such as aneurysms or obstructive lesions without any surgical intervention;
• It allows for evaluation of a greater area because it covers an entire organ instead of just certain areas or vessel paths;
• Its cost effectiveness saves money in both testing fees and potential follow up treatments when compared with standard techniques;
• The study results are available within minutes after completion of the test allowing for timely treatment options that would otherwise have taken days or weeks.
Overall, these benefits make CTA an ideal choice for diagnostic imaging involving vessels in many cases due its accuracy, safety profile, convenience and cost effectiveness.
