- “Compared with digital subtraction angiography, sensitivity, specificity, and accuracy, respectively, of CTA was 97.2%, 94.1%, and 94.7% by the dual-energy bone removal technique. The conventional bone removal tool delivered a sensitivity of 77.1%, a specificity of 70.7%, and an accuracy of 72.0%.”

"Our data suggests that 64-slice MDCT could be used to assess the abdominal aorta and lower extremity arteries with a reduction of table speed to allow adequate arterial opacification and minimal venous contamination. We recommend different table speeds for each patient age group as a guideline for routine CTA of the lower extremity."
