Dear Advanced Visualization Insider,
Despite its success at boosting the sensitivity of radiologists in detecting lung nodules, computer-aided detection (CAD) software still engenders varied opinions on its most effective method of use.
Are radiologists better off using CAD as a second reader following an initial read? Or should they employ it concurrently during interpretation?
Researchers from the University of Verona in Italy sought to tackle this issue in a retrospective study involving 100 cases. The second-reader approach worked best, yielding a statistically significant improvement over both the use of CAD as a concurrent reader and reading without CAD.
However, the readers who used CAD concurrently failed to produce a significant improvement in sensitivity compared to reading without CAD, according to Dr. Giovanni Foti. Our coverage of the research is the subject of this month's Insider Exclusive article, which you can access before our other members by clicking here.
The concurrent-reader model for lung CAD fared better in another presentation at the ECR meeting. A study team from Catholic University in Rome found that the method could improve the performance of inexperienced readers in detecting lung nodules on PACS workstations.
