Objective To investigate the diagnostic value of technologies for arteriovenous malformation(AVM ) ,which are skull to boneless head CTA by surface shaded display technique (hereinafter referred to as the SSD‐CTA technology) .Methods Totally 27 patients of the First Affiliated Hospital of Chongqing Medical University were selected ,which were diagnosed with AVM by VCTDSA .The original data to our hospital CT workstation were imported ,SSD‐CTA technology to bone reconstruction were performed ,and the data of the two groups were compared .Another 5 patients in our hospital which were diagnosed with AVM by SSD‐CTA examination were selected ,and compared the results with DSA .Results The quality score of SSD‐CTA reconstructed image was less than that of VCTDSA ,but the diagnosis of the two technologies for AVM had no significant statistical difference (P>0 .05) .The number of AVM patients from our hospital wsa too less to do the statistical analysis .The detail resolution of SSD‐CTA was less than DSA ,but the diagnosis of SSD‐CTA was consistent with DSA .Conclusion SSD‐CTA has clinical practical val‐ue ,can be used as a check ,intracranial venous malformation diagnosis .
