Researchers involved in a large, multi-institutional study comparing the accuracy of positron emission tomography (PET) and computed tomography (CT) in the characterization of lung nodules found that PET was far more reliable in detecting whether or not a nodule was malignant.
"CT and PET have been widely used to characterize solitary pulmonary nodules (SPNs) as benign or malignant," said James W. Fletcher, professor of radiology at Indiana University School of Medicine in Indianapolis, Ind. "Almost all previous studies examining the accuracy of CT for characterizing lung nodules, however, were performed more than 15 years ago with outdated technology and methods, and previous PET studies were limited by small sample sizes," he noted.
