Is there a big difference in accuracy between cardiography and cta?

The difference in accuracy between cardiac imaging and CTA is not significant. Usually, it requires a comprehensive assessment of the doctor’s condition and the selection of the corresponding test according to the indications.
Cardiac imaging is an invasive operation, which mainly involves making an incision in the radial artery, delivering a guide wire to the coronary artery, and injecting a contrast medium for the examination, which can observe the whole coronary aorta and the branch vessels, and make clear whether there is any blockage or plaque lesion in the vessels, and meanwhile stent implantation can be carried out to unblock the blocked vessels during the operation. However, postoperative bleeding, hematoma, and contrast nephropathy may occur.
CTA is a non-invasive procedure, which mainly involves the injection of iodine contrast agent and imaging of coronary vessels to clarify the degree of coronary artery stenosis or intravascular plaque lesions. It has the advantages of repetition, non-invasiveness and low risk, but it is not able to carry out relevant treatments after the detection of vascular blockage.
In summary, the accuracy of cardiac imaging and CTA is not much difference, both can accurately observe whether there is stenosis or plaque lesions in the coronary arteries. However, cardiography can be used to unblock blood vessels, while CTA can be used for those who cannot tolerate surgery. Therefore, it is important to choose the appropriate test after evaluating your condition.
