SASKATOON -- The Saskatoon Health Region says diagnostic images have been lost for 206 patients.

The images , including CT scans and X-rays, were taken between March and June.

Officials say the images were fortunately assessed by radiologists and reports about the tests were passed on to doctors.

The images were supposed to be stored in an archiving system but for some reason can not be recovered.

The problem was discovered two weeks ago.

An investigation is underway by Philips Canada, the company contracted to operate the archives.
