RSNA 2011: Practical considerations in lung cancer screening: Interpreting the NLST

So far, the influence of this data has been modest, judging by a poll of an audience attending a special RSNA symposium on this topic. In the poll, only 25% reported that they now offered low-dose CT scanning for high risk individuals, such as those with >30 pack-year history of smoking. One obstacle is that few third-party payers currently reimburse low-dose CT screening, but this may change as the significance of the NLST results is better explained.
