CAD gains ground on pulmonary embolism

May 1, 2008 Diagnostic Imaging. CAD gains ground on pulmonary embolism H. A. Abella -------------------------------------------------------------------------------- Computer-aided detection may lend an extra punch to the diagnosis of pulmonary embolism with multislice and dual-energy CT scanners. Studies by French and German researchers have shown it helps detect small, hard-to-spot clots lodged in the lungs' periphery. Multislice CT angiography has become the diagnostic standard in pulmonary embolism, with a well-established accuracy in the detection of proximal lesions. But CTA detection of peripheral PE remains challenging and time-consuming, and it may lead to false positives. Can CAD pick those small clots missed by the radiologist's naked eye in the first read? Yes, it can, said the principal investigator of a study from France.
