Diagnostic accuracy of dual-source CT coronary angiography in obese and non-obese patients

3rd-generation dual source CT angiography with automated tube voltage selection provides a high diagnostic accuracy for detecting significant stenoses in coronary arteries.  Detection accuracy was not significantly different between non-obese and obese patients, thus current radiation dose-saving approaches can be applied independent of body habitus.

Key points:

  • Coronary CTA provides high diagnostic accuracy in non-obese and obese patients.
  • Diagnostic accuracy between obese and non-obese patients showed no significant difference.
  • <120 kV studies were performed in 44 % of obese patients.
  • Current radiation dose-saving approaches can be applied independent of body habitus.
