Daily Aspirin May Help Prevent Colon Cancer

In big news last week, results of a study suggest that taking aspirin daily, may help prevent colon cancer in people who have a known genetic predisposition for the disease.  After five years of taking the aspirin, high-risk patients in the study had their cancer risk reduced by 50%.

Aspirin alone – whether a person is high-risk or not – is not the entire solution. Regular screening for colon cancer is a MUST.  There are several types of screening tests available including CT Colonography (“Virtual Colonoscopy”) which the American Cancer includes as one of its recommended screening exams.  As part of his health check, President Obama underwent Virtual Colonoscopy last year.

Canada Diagnostic has been offering Virtual Colonoscopy since 2002.  All of our Radiologists have full College of Physicians & Surgeons of BC Certification to read Virtual Colonoscopy.  To learn more about Virtual Colonoscopy, please take a look at our info sheet:  QA – Virtual Colonoscopy.

CT Lung Cancer Screening – Named one of the Top 10 Medical Innovations for 2012

World-renowned Cleveland Clinic just held their annual Medical Innovation Summit and have announced their Top 10 Medical Innovations for 2012– the technologies and innovations that will have the biggest impact on healthcare next year.

Did you know that Lung Cancer is the #1 cause of cancer-related deaths in North America?  Lung Cancer accounts for more deaths each year than Breast, Prostate, Colon and Pancreatic  cancer combined.  And now we have a tool that has been shown to help reduce the number of deaths each year from lung cancer.

The #2 Innovation is CT Lung Cancer Screening  which the Medical Innovation Summit says:

This high-tech scan generates a series of detailed cross-sectional images of the lungs that are used to create a three-dimensional image. These scans can not only identify tumors earlier, but also spot them when the tumors are smaller and more treatable by surgery. Surgery is the best treatment for most types of lung cancer. 

If caught earlier through screening, the potential to save lives is great: Upwards of 60 to 90 percent of lung cancers are curable in the early stages. Screening for colon, breast, and cervical cancer has been shown to reduce the risk of dying from these cancers compared to those who are not screened.

CT Lung Cancer Screening Cuts Deaths

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.”

Improve your heart disease risk

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.

If its good enough for the President of the U.S……..

As part of his first annual comprehensive physical exam as Chief Executive, U.S. President Barack Obama underwent a Virtual Colonoscopy (VC) exam as a screen for colon cancer. 

Why did the President’s medical team choose a VC over a traditional colonoscopy?  The exam is safe, effective and does not require sedation or pain medication.  Because there was no sedation, the President was able to maintain presidential authority.  In contrast, when President George W. Bush had a traditional colonoscopy in 2007, because he had to undergo sedation, he had to transfer presidential authority for several hours to his Vice President.

You may not be governing one of the most powerful nations in the world, but knowing that a VC is the test of choice for someone who does carries a pretty strong message!

The Canadian Cancer Society advises that the death rate from colorectal cancer can be reduced significantly if patients get screened!

Colon cancer and cancer of the rectum usually begin as a small polyp. While most colon polyps are benign, some do become cancerous. Colon cancer symptoms may include a change in bowel habits or bleeding, but usually colon cancer strikes without symptoms. That’s why it’s important to get a colon cancer screening test, such as a Virtual Colonoscopy. If the cancer is found early, the doctor can use surgery, radiation, and/or chemotherapy for effective treatment.

What to look for in a Diagnostic Imaging Centre

We understand that you have choices when it comes to deciding where to go for your scan.  What should you consider when you are looking for an imaging centre?


Canada Diagnostic Centres opened the first private MRI in Canada in 1993.  Our Vancouver clinic has been open since 2000 and since that time we have scanned over 35,000 patients.  Our facility and our radiologists are well known in the medical community.

Medical Team

Radiologists are the specialists who interpret, MRIs, CTs and ultrasounds and provide your doctor with the results. 

Our clinic’s five radiologists are led by Dr. Bruce Forster, a Professor of Diagnostic Radiology, Faculty of Medicine at UBC and a practicing radiologist at UBC and VGH.  Dr. Forster is also head of the MRI fellowship program at UBC Hospital and Regional Head of MRI for Vancouver Coastal Health Authority.

 Our radiologists also bring a variety of sub-specialty skills to the clinic relating to musculoskeletal, neurologic and abdominal diagnostic imaging.  They use a team approach and are able to consult freely with each other in the event of challenging or difficult cases.  This depth and breadth of knowledge is a real benefit to our patients and their physicians.

Our entire team of radiologists actively participates in teaching of radiologists-in-training in the UBC Faculty of Medicine and is engaged in cutting edge imaging research.

The Right Exam for the Right Reasons

There are many considerations as to which exam is most appropriate for each individual case, and even how to structure each exam.  For that reason, our radiologists review and protocol all exam requests before we call you to book a scan.  If a different exam than the one ordered by your doctor would be more appropriate for you, our radiologists will let you and your physician know.  That way, we maximize the likelihood that we will get the answers you need and minimize the likelihood that you will need an additional, different kind of exam down the road


Just like cars, advanced medical imaging equipment comes in different makes and models.  With MRI for example, there are many different configurations as to the size, shape and strength of machine. 

The strength of the magnets in an MR machine is measured in Tesla.  The most common strength machine is a 1.5Tesla and it is what you will find in hospitals and medical teaching facilities throughout Canada.  At our clinic, we operate a GE Signa 1.5T HDx(High Definition) MRI. 

CT scanners are described by the number of “slices” they have.  These are the number of simultaneous images the machine takes during one split-second rotation around the patient.  Our CT scanner is a 64-slice Aquilion 64-slice by Toshiba Medical.  64-slice scanners have made  high resolution visualization of the heart and coronary arteries possible.


When you call an imaging clinic, is the staff helpful and informative?  Are they able to answer all of your questions?  Are you comfortable with what they are telling you?  If you need more information, are they able to provide it for you?  At Canada Diagnostic Centres, our staff is happy to answer all of your questions or provide you with information or materials you may find helpful.  If you prefer online research, our website is an excellent source of information.



Wait times

Do you need your scan done as soon as possible or would you like it next Tuesday afternoon to better fit your schedule?   At Canada Diagnostic Centres, we will do our absolute best to schedule your scan for a time and date that fits with your needs.  We will also be happy to coordinate the timing of your scan with specialist appointments or treatment you have scheduled. 

In addition, your scan will be reviewed and reported quickly.  You doctor will receive a report within one working day of the exam—in many cases, your doctor will receive the report within a few hours of your scan.  If your doctor requires results immediately, our radiologist will be happy to call and give a verbal report right away.



Prices for different scans vary depending on the complexity of the scan being done and the type of machine it is being done on.  A complete fee schedule is available on our website.  If you have any questions about what an exam would cost, please give us a call.

Our promise is to provide our patients and their physicians with the best in patient-focused, medically-principled diagnostic imaging.

Virtual Colonoscopy finds cancers outside the colon

March 23, 2010 – A study of more than 10,000 asymptomatic screening subjects found that more than one in 200 had unsuspected and typically large but mostly early-stage cancers detected outside the colon at Virtual Colonoscopy.  As with asymptomatic colorectal cancers identified by Virtual Colonoscopy screening, these cancers outside of the colon are often detected at an early, curable stage.

Coronary Artery Calcium & Risk Classification/prediction

April 28, 2010 – The results for the Multi-ethnic Study of Atherosclerosis (MESA) have been published in the Journal of the American Medical Association.  Over 6,800 patients were screened – half using traditional risk factors such as age, gender, smoking history, blood pressure, cholesterol and ethnicity.  The other half were screened for traditional risk factors, plus received a Coronary Artery Calcium scoring test.

The study concluded that adding CACS to a prediction model “significantly improved” the classification of risk.

Did you know?  Risk factors such as high cholesterol, overweight etc do not tell you whether you have any biological evidence of early atherosclerosis.  Coronary Artery Calcium Scoring (CACS) and Carotid Intima-media thickness (CIMT) are two screening tests that can accurately measure actual changes within your body that indicate early atherosclerosis.

Give us a call to find out more about CACS and CIMT testing at Canada Diagnostic:  1-877-709-8522 or 604-709-8522
