By Wayne Forrest
There is no doubt in the healthcare community that multislice CT finds more potentially cancerous lung nodules than chest x-ray. But CT's efficacy in reducing mortality among patients with suspicious lung nodules has become considerably less conclusive and more divergent with the release of two recent research reports.
