Digital subtraction angiography and multislice computed tomography angiography for cervicocranial vessels: comparison of radiation doses

Abstract

Aim: In this study our purpose was to compare the digital subtraction angiography (DSA) and computed tomography angiography (CTA) techniques in terms of the superiority of diagnosis and radiation doses. Materials and Methods: Forty-six patients (21 men, 25 women) who were subjected to both digital subtraction angiography (DSA) and computed tomography (CT) neck-brain angiographic examinations between January and December 2014 were screened retrospectively. Radiation dose records taken from the cards provided by DSA and CT devices were reviewed. The total DSA [DSA+ tri-dimension (3D) DSA], DSA, 3D-DSA and CTA dose reports were examined separately. Generated 3D images were evaluated by two radiologists who had experience in neuro radiology and interventional radiology at least for five years. Independent samples test and in dual comparisons the paired samples test, were used for statistical analyses. Results: Comparison made between DSA and CTA radiation doses has found that the total dose of total DSA (DSA+3D DSA) was three times and the DSA doses were two times higher than the CTA dose. There was no statistical difference between 3D DSA and CTA doses. CTA is less sensitive than DSA; four of 68 intracranial aneurisms could not be demonstrated with CTA. The radiation doses received by patients did not change with gender. Conclusion: CTA contains less radiation doses in the diagnosis of intracranial aneurisms, but its sensitivity, however, is lower than DSA.
