Lung cancer screening by CT, or computed tomography, can reduce lung cancer deaths by detecting the disease at early stages, a new study from the National Cancer Institute says. It was the first time researchers saw a reduction in death as a result of lung screening, experts said.
In the National Lung Screening Trial (NLST), more than 53,000 current and past heavy smokers between the ages of 55 and 74 were screened for lung cancer by either low-dose CT scan or standard chest X-ray. Researchers found 20 percent fewer deaths in those screened by CT scan. The data were so statistically convincing the trial was stopped and the results released.
The results demonstrate that such CT screening could benefit older, high-risk patients, aid Dr. Denise Aberle, NLST national principal investigator for the American College of Radiology Imaging Network (ACRIN).
“We have the potential to save thousands of lives,” if low-dose screening is implemented responsibly, and people with abnormalities are closely followed, Aberle said.
Trial participants smoked at least a pack a day for 30 years and had no symptoms or history of lung cancer. They were screened once a year for three years and followed for an additional five years.
“This is the first time that we have seen clear evidence of a significant reduction in lung cancer mortality with a screening test in a randomized controlled trial,” said Dr. Christine Berg, NLST project officer for the Lung Screening Study. “The fact that low-dose helical CT provides a decided benefit is a result that will have implications for the screening and management of lung cancer for many years to come.”

A new study in the Journal of the American College of Cardiology (JACC, April 12, 2011, Vol. 57:15) found that patients who had a screening CT scan of the heart which showed evidence of calcium in their coronary arteries made important lifestyle changes that helped lower their risk of having a cardiac event in the future.
A large number of studies have now shown that a Coronary Artery Calcium Score or CACS improves assessing a patient’s actual risk factors for heart attacks.
Canada Diagnostic has been providing Coronary Artery Calcium Scores since 2002. This exam is quick, painless and provides some very important information that just might save your life.

Have you been suffering with chronic pain because of a tendon that just won’t heal?
There’s a new technique that uses your own blood to help heal the injury and eliminate your pain.
PRP – or platelet-rich plasma – is being used by sports medicine and orthopedic specialists to help heal chronic tendinopathies. Because tendons and ligaments have a limited blood supply, there are often not enough platelets to properly heal the injury.
PRP helps eliminate that problem, by providing a concentration of your own platelets directly at the injury site that may promote healing. As the tissue repairs itself, your pain gradually subsides and functionality is restored.
But, there is even better news! An exciting new development in the world of PRP is called hcPRP or highly-concentrated platelet-rich plasma. Most PRP practitioners use a platelet concentration of 5 – 8 times the amount that normally circulates in your blood. With hcPRP, those concentrations are 25 – 45 times baseline PLUS, thrombin from your blood is added just as the hcPRP is injected. Thrombin helps activate the platelets so that they can be more effective.
Canada Diagnostic is now offering hcPRP injections at our Vancouver clinic. Our doctors use either an ultrasound or CT scanner to help them ensure that the hcPRP injection goes precisely where they want it to go – another way to ensure the treatment will be effective!
PRP / hcPRP is still considered investigational or experimental, but many of the scientific studies that have already been done show that PRP is very promising.
