An update of a review of a Yorkton, Sask., radiologist has found that about two per cent of roughly 40,000 examinations he performed had the potential to negatively affect the patient.

On Wednesday, the Sunrise Health Region released its latest set of findings on the work of Dr. Darius Tsatsi, who was one of three radiologists s with privileges at Yorkton Regional Health Centre, about 200 kilometres northeast of Regina.

In May, Tsatsi agreed to a voluntary suspension while the Saskatchewan Health Ministry ordered a massive review of his work.

That review is still underway, with 39,711 out of 47,646 radiology exams having been re-read.

The health region says 946 of those exams — or 2.38 per cent — have "discordances" that could affect the patient. It didn't say whether anyone's health was affected, only that there was a potential for it to have been affected.

Another 5,804 (14.6 per cent) were considered "substantially correct with minor discrepancies." With the rest, there was no difference of interpretation.

The region didn't provide any analysis of the numbers or say what an acceptable problem rate is.

The exams reviewed were initially done in the period from 2007 to 2009. Those that still remain to be reviewed are from 2004 to 2006.

Radiologists are involved in interpreting x-rays and magnetic resonance imaging scans, including those for cardiac and cancer patients.
