Canada Diagnostic Centres Privacy Statement

Canada Diagnostic Centres respects the privacy of its visitors to our website and is committed to maintaining the confidentiality and security of your personal information. As part of this commitment, we have established Privacy Principles to govern our use of patient and client information.

CDC complies with two privacy laws. One is healthcare-related and the other is business-related. In Alberta, when personal information is collected, used or disclosed in the course of providing publicly-funded healthcare services it is covered by the Health Information Act (HIA). At the same time, the Personal Information Protection Act (PIPA) protects personal information collected, used or disclosed by private-sector companies, including CDC. In practice, the requirements of these laws are reasonably similar and can be satisfied at the same time. Where standards differ, we meet the higher one.

We make information about our privacy policy and practices available to our patients. If you are unsure about which law applies to your information and what that means for you, or if you have any other privacy questions, requests or concerns, please refer to the Contact Us Section below.


By accessing and using our “Request an Appointment” services on this Site, you will have provided your implied consent to our collection, use, or disclosure of your personal health information in accordance with this Policy, for the purpose of scheduling diagnostic exams.

Principle 1 – Collection of Personal Information

Our website is used to inform our visitors about Canada Diagnostic Centres and our services. Should you require additional information about Canada Diagnostic Centres you may be asked to provide personal information such as your name, e-mail address, mailing address, phone number and information request. This information will be collected in a secure portion of the Web site and only used by internal personnel responsible for administering information requests.

Principle 2 – Information Disclosure

Personal information about visitors to our Web site is not disclosed to any third parties. It is also not shared with Canada Diagnostic Centres personnel who do not require such information to perform their job duties.

Principle 3 – Personal Information Collected & Used

To properly administer and understand the technology we need to support this Web site, we may collect and log the location portion of the Internet Protocol (IP) address for incoming traffic to the site (e.g. @internetserviceprovider.ca). We do not capture or link these addresses with the identity of individuals visiting our Web site.

Mammography & Breast Imaging

BIRADS* Interpretation Guide:
  • BI-RADS 0:Imaging investigation not yet complete.
  • BI-RADS 1:No abnormality; return to regular screening.
  • BI-RADS 2:Definitely benign finding; return to regular screening.
  • BI-RADS 3:Probably benign finding (<2% likelihood of cancer); 6 month follow up recommended.
  • BI-RADS 4:Suspicious for malignancy (2-95% likelihood of cancer); biopsy recommended.
  • BI-RADS 5:Malignancy until proven otherwise (>95% likelihood of cancer); appropriate action must be taken.
*Breast Imaging Reporting and Data System (American College of Radiology)

General Recommendations


Canada Diagnostic Centres is adopting Alberta's 2013 Towards Optimized Practice guidelines on breast cancer screening. In summary these suggest:

  • Annual mammographic screening for women age 40-49 who chose to begin screening early;
  • Biennial mammographic screening (every two years) for women age 50-74 with average risk for breast cancer, but annual screening for those with higher risk;
  • Biennial mammographic screening to continue if appropriate for women 75 and older;
  • Consideration of screening ultrasound as an adjunct to mammography in women with dense breast parenchyma, as identified by a Radiologist.

For further reference, the Canadian Association of Radiologists recommends annual screening beginning at age 40 for all women, every one to two years from age 50-74, and from 75 onward if they are in good general health.

Diagnostic Studies

Imaging tests do not detect all breast cancers. If there is ongoing clinical suspicion for malignancy despite a negative imaging work-up, further management based on the clinical findings alone should be pursued including possible biopsy.

Bone Mineral Densitometry

Diagnostic Categories (2013 CAR Reporting Guidelines)

Patient Group Category Name T-Score Value Z-Score Value
50 Years and older Normal >= -1.0
Low bone mass Between -1 and -2.5
Oseoporosis <= -2.5
Under age 50 Within expected range for age > -2.0
Below expected range for age <= -2.0
Fracture Risk and Treatment:

Canada Diagnostic Centres follows the 2010 Clinical Practice Guidelines for the Diagnosis and Management of Osteoporosis in Canada, and the 2013 Canadian Association of Radiologists Technical Standards for BMD Reporting, to interpret BMD exams and to derive a 10 year absolute fracture risk for each patient 50 and older. Treatment is based primarily on this risk level.

Pharmacologic fracture prevention therapy should be offered to those at High risk, and should also be considered for some patients with specific clinical factors otherwise placed at Moderate risk.

Vitamin D supplementation, adequate dietary Calcium, and targeted exercise are recommended for all patients.

Patients with a T-score of -2.5 or lower (Osteoporotic) should have biochemical tests including:

  • 25-Hydroxyvitamin D level, serum calcium (albumin corrected), CBC, creatinine, alk phos, and TSH;
  • Those with vertebral fractures should also have serum protein electrophoresis as well.

General Information:

The Osteoporosis Society of Canada recommends that BMD be performed at least once in all patients aged 65 and over, in addition to other potential indications in younger patients.

The International Society for Clinical Densitometry recommends that follow up BMD studies be performed on the same machine at the same centre as the previous study, for maximum sensitivity and accuracy in assessing change.

Referral Guides(Provided by the Canadian Association of Radiologists)

The 2012 CAR Diagnostic Imaging Referral Guidelines are intended for physicians and are aimed at assisting them in making decisions in regard to appropriate imaging studies for specific cases. These Referral Guidelines are not intended as a means of restricting the physician’s role in the process of decision-making in regard to the imaging studies to be requested. The Referral Guidelines are evidence-informed and are based on expert opinion or case studies. They should not be used to diminish in any way the freedom of attending physicians to determine and order imaging studies for their patients for whom they have the ultimate responsibility. Discussion between the radiologist and the physician, particularly during multidisciplinary team meetings, must always take precedence.

Radiation Safety

Is medical radiation safe?:

In short, yes. Media reports sensationalizing the risks associated with radiation are a popular topic.

However, there is an old adage that a little knowledge is a dangerous thing, and this certainly applies to the complex issue of medical radiation.

While caution is appropriate in children especially, reflex avoidance of all radiation is not necessary or helpful, should not be confused with Choosing Wisely, and should not prevent patients from receiving the Best Test First® for their condition when indicated (be that a CT scan or other investigation.)
