Diagnostic study reveals suboptimal sensitivity of CTA and MRA for blunt cerebrovascular injuries in asymptomatic trauma patients, indicating arteriography remains the gold standard.

Key Points

To determine the diagnostic accuracy of computed tomographic angiography (CTA) and magnetic resonance angiography (MRA) compared to catheter arteriography for detecting blunt cerebrovascular injuries in asymptomatic patients.
Asymptomatic patients meeting blunt cerebrovascular injury (BCVI) screening criteria underwent standard arteriography alongside either CTA (n=46) or MRA (n=16).
Radiologists interpreted all imaging studies in a blinded manner to assess sensitivity, specificity, and predictive values relative to arteriography.
CTA demonstrated a sensitivity of 68%, specificity of 67%, positive predictive value of 65%, and negative predictive value of 70%, missing 55% of grade I, 14% of grade II, and 13% of grade III injuries.
MRA demonstrated a sensitivity of 75%, specificity of 67%, positive predictive value of 43%, and negative predictive value of 89%, producing 1 false-negative and 4 false-positive interpretations.
