Since the introduction of spiral computed tomography (CT) scanning in the 1990s, researchers and physicians have been hopeful that the imaging tool would be helpful in detecting early, localized lung cancers that could be successfully treated. Uncontrolled studies showing that spiral CT can detect small-sized lung cancers have nurtured this hope, but the clinical significance of the findings of these studies remains unclear.

Despite a lack of evidence about whether spiral (also called helical) CT screening for lung cancer saves lives, direct-to-consumer marketing has increased demand for the procedure. However, the results of a recent study that used a computer-simulated model of 100,000 current, quitting, and former smokers older than age 60 suggest that screening for lung cancer with spiral CT scanning may not be cost-effective. CT scanning is readily available at commercial facilities or even in a hospital setting, and . . . [Full Text of this Article]
