Screening came about following the publication of The National Lung Screening Trial. The randomized trial compared CT scan with chest X-ray in smokers over the age of 55 with a 30-year smoking history. The trial demonstrated the first reduction in mortality for patients who had been screened with CT scan.
In 2014, the United States Preventative Task Force gave this a B recommendation. In 2015, Medicare approved screening, and since then it has become more available. However, it is considerably underutilized, says Rivera. As of 2015, only 3.9% of eligible patients were being screened in the United States. This may be due, in part, to the difficulty of getting an accurate smoking history.
