Objective To investigate the value of head boneless CT angiography (CTA) for surface shaded display (SSD) (hereinafter referred to as the SSD-CTA technology) and volume computed tomographic digital subtraction angiography (VCTDSA) in diagnosing intracranial aneurysms. Methods We collected the clinical data of 35 patients diagnosed to have intracranial aneurysm by VCTDSA between April 2013 and November 2014 from the First Affiliated Hospital of Chongqing Medical University. The original data were imported into the CT workstation of the First People's Hospital of Chengdu. Then, SSD-CTA technology was performed for bone reconstruction. We compared the results of these two technologies. In addition, we selected another 27 patients diagnosed with intracranial aneurysm by SSDCTA and DSA examination at the same time between June 2012 and November 2014 in the First People's Hospital of Chengdu for comparison. Results The quality score of SSD-CTA reconstructed image was lower than that of VCTDSA, but the diagnosis of the two technologies for intracranial aneurysm was not statistically different (P>0.05). Compared with DSA, the sensitivity and specificity of the diagnosis for intracranial aneurysms by SSD-CTA were both 100%. Conclusion SSD-CTA is valuable in diagnosing intracranial aneurysms.
