Update: Multi-Patient Occurrence in Central Health – Mammography Images

September 6, 2022

Central Health wishes to provide an update on the multi-patient occurrence concerning the viewing of some mammograms on workstations that do not meet technical standards specifically for the review of mammography images. We apologize for the concern this occurrence has caused, and we remain committed to regular communication on this topic.

The full review of images read on 3 megapixel monitors instead of 5 megapixel monitors is underway. We want to clarify that five megapixel monitors are the standard for the review of mammography images, while 3 megapixel monitors are the standard for all other types of images, such as X-rays and CT scans. These occurrences are not a result of the use of defective monitors.

As of September 6th, we can confirm that the images of 2,564 patients have been reviewed and nine patients requiring further follow-up have been identified, in total. The number of potential discrepancies or differing opinions identified to date in our review remains low, suggesting the occurrence presents a low risk to patients.


The images of 523 patients remain to be reviewed and will be completed by end of September.

We are still gathering information about this occurrence and are currently in the initial phases of an internal quality review, which will inform a multi-RHA review. Please be assured that Central Health is taking all the necessary steps to address this occurrence in a timely and thorough manner.

As a reminder, if your mammography images are under review, please know that Central Health has reached out to you directly to inform you. Patients whose images do not show any potential discrepancies or differing interpretations will receive a letter from Central Health by the end of September verifying this. For those patients whose images show potential diagnostic discrepancies or differing interpretations, Central Health will be reaching out to their primary health care provider, contacting the patient by phone, and following up with a letter. These measures will be taken by the end of September to make them aware of next steps.

A toll-free line for those with questions is available from 8:00 am to 4:00 pm weekdays at 1-833-960-4571.
