Lung Cancer Screening Gets Another Leg Up

Symbol kept vote Green by Zorglub via Wikimedia Commons Copyright Creative Commons Attribution-Share Alike 3.0 UnportedThe votes in support of low-dose screening CT chest for high risk smokers are growing. Recently the American Medical Association – the largest association of doctors from all specialties in the US – added their support to guidelines recommending this potentially life-saving exam.


Lung cancer is a killer. In the US, lung cancer causes more deaths than breast + prostate + colon cancer – more deaths than all of those cancers combined! Studies on low-dose CT screening (the National Lung Screening Trial) showed early detection saves lives! There was a 20% reduction in deaths in heavy smokers from lung cancer due to CT screening in this study. This is why low dose chest CT is so crucial. Finding lung cancer early, when it is potentially treatable is the goal of screening.


As accredited members of the American College of Radiology, we are thrilled that the ACR is fighting to support the recommendations of the United States Preventative Services Task Force for high-risk patients. (Read all about it here.) The Task Force recommended coverage beginning January 2015 for high risk patients, including those 55-80 years with significant smoking histories (defined as greater than a 30 pack-year history of smoking) or for those who were former heavy smokers who have quit in the last 15 years. The Task Force recommendations will apply to those patients with insurance.


The fight for coverage of Medicare patients is still on-going, and is the focus of the ACR and other groups. The Medicare Evidence Development and Coverage Advising Committee made a controversial stand against support of low-dose CT screening early this year. Medicare will make its final vote in the fall. We think including Medicare patients in coverage for this important, potentially life-saving exam is crucial.

Make your voice heard – add your vote in favor of low-dose screening CT chest for all who will benefit- including Medicare patients! Contact your local congresspersons (here) and let them know you agree.

Heart Health: CT Coronary Calcium Score

It’s heart month! We are joining with the American Heart Association in trying to raise awareness of the leading killer of women and men. In the past, we’ve explained the basics of a CT scan,  and today we’d like to talk about a specific use of the technology to obtain a CT Coronary Calcium Score.

A Coronary Calcium Score is a scan of the heart which evaluates the arteries for the presence of calcium. Calcium build up in the arteries is one part of coronary atherosclerosis – the process by which arteries are narrowed by buildup of plaque, both calcified and noncalcified (soft). Finding calcium in the arteries of the heart indicates coronary artery disease and is associated with an increased risk of future cardiovascular events, like heart attacks.

Obtaining a calcium score is a simple, quick, painless procedure. You will have EKG leads placed and then a quick scan of the heart will be done with the CT machine. No contrast is needed. Your study will be reviewed by your radiologist with computer assisted analysis. All calcium related to the coronary (heart) arteries will be identified, and a summation of the amount of calcium present will be reported. The score will be compared with others of the same age and sex.

The calcium score will give an estimate of the likelihood of significant coronary artery disease. It is important to remember that not all coronary artery disease will be calcified. Soft areas of plaque will not be found by this technique.

Coronary calcium score is a useful tool to consider for anyone in an intermediate risk category for heart disease or in some low-risk patients, especially those with a family history of early heart disease (before the age of 55 in a man or 65 in a woman).

What places someone in an intermediate risk category? Things like smoking, a family history of heart disease or high cholesterol can be factors. To determine your risk for heart disease, the Mayo Clinic has an excellent tool, found here. In intermediate and low risk patients, a calcium score can be an important independent predictor of the risk of future heart problems.

Recently, the American College of Radiology has reviewed the recommendations to determine the relative importance of getting a calcium score for different risk category patients. Their thorough statement and review can be found here.

For all, remember that cardiovascular disease is a leading killer. Take action to find out your risks and ways you can improve your heart health.
