Dr. Darius Tsatsi, seen at a July 2009 news conference, is at the centre of a review of thousands of diagnostic tests in Saskatchewan.

Dr. Darius Tsatsi, the Saskatchewan radiologist whose work sparked a review of 70,000 diagnostic exams, has not renewed his medical licence in the province, according to the body that oversees doctors.

Bryan Salte, from the College of Physicians and Surgeons of Saskatchewan, says Tsatsi was due to renew his licence at the start of the year but did not.

Tsatsi is scheduled to appear before the college council Friday to discuss his fate after he failed a competency test for radiology.

Salte said he'll ask the council to order that Tsatsi not be allowed to practise radiology in Saskatchewan. Such an order could be reviewed later if, for example, Tsatsi gets more training, Salte said.

Tsatsi voluntarily stopped practising in May after concerns were raised about his interpretation of images, such as X-rays and CT scans, and the review was ordered.

The Sunrise Health Region, where Tsatsi did most of his work, said in November that the review was more than half complete and flaws were found in just over two per cent of the cases.
