OBJECTIVE. To evaluate the potential for surveillance of abdominal aortic aneurysms without ionizing radiation exposure and without the risks of iodinated contrast administration, the accuracy of fusion of CT angiography (CTA) with ultrasound (US) was compared with conventional US in 14 patients. CONCLUSION. The mean measurement difference between conventional US and CTA was 0.50 cm, compared with 0.13 cm between CT-US fusion and CTA (p < 0.0005). CT-US fusion was more accurate than conventional US, reduces operator dependence, and is promising for accurate measurement of aortic aneurysms.
