The article presents the author's comments on how multidetector CTA with venography is more sensitive for diagnosing pulmonary embolism than CTA alone. Specificity of multidetector CTA was high, but the observed sensitivity of 83% was somewhat disappointing, even though it was higher than that of single-detector CT 70%. CTV had increased sensitivity (90%), but is it more useful. It only increases the negative predictive value from 95% to 97% in the overall population.
