While CTA is generally safe, there are some risks and limitations:
Contrast Material Reactions: Some patients may experience allergic reactions to the contrast material, ranging from mild to severe. Radiation Exposure: CTA involves exposure to ionizing radiation, which may be a concern, especially with repeated scans. Limited Soft Tissue Contrast: Although excellent for vascular imaging, CTA may not provide as much detail for soft tissues compared to MRI. Not Suitable for All Patients: Patients with certain conditions, such as severe kidney disease, may not be eligible for CTA due to the risks associated with contrast material.
