Demonstrates that multidetector CTA-CTV improves diagnostic sensitivity over CTA alone in suspected pulmonary embolism, highlighting the need for concordant clinical assessment.
In patients with suspected pulmonary embolism, multidetector CTA-CTV has a higher diagnostic sensitivity than does CTA alone, with similar specificity. The predictive value of either CTA or CTA-CTV is high with a concordant clinical assessment, but additional testing is necessary when the clinical probability is inconsistent with the imaging results.
