Motion and contrast problems spoil CTPA most often

Multidetector-row CT scanners have increased the accuracy of CT pulmonary angiography (CTPA) to 90% and higher for detecting pulmonary embolism, triaging patients in the emergency room, and ultimately sparing lives. In the small percentage of indeterminate CTPA findings, however, motion artifacts and contrast delivery are usually to blame, according to researchers in France.

Triage with chest x-ray expedites PE evaluation

By Tracie L. Thompson

Multidetector CT pulmonary angiography (CTPA) may be the best noninvasive exam for diagnosing pulmonary embolism (PE), but using it in every suspected case may not be desirable or even possible given the associated radiation burden and contrast risks. Now researchers are touting plain x-rays to determine who needs CTPA versus scintigraphy.

Despite flaws, lung CAD earns second-reader role

In a new study from Canada, a popular lung CAD application proved its value as a second reader of low-dose thoracic CT studies, detecting lung nodules that had been missed in a double reading by radiologists. Yet the application also produced large numbers of false positives, and some troubling false negatives.
