Cromwell residents have been told the backers of a CT scanner in Queenstown have exaggerated their case for the facility to be located in the resort.
Dunstan Hospital officials told a meeting in the town on Tuesday night that the scanner should be located at Clyde.
Central Otago Health Services director Graham Ballantyne says Queenstown's rationale is that many injured skiers will need the facility.
But he said only 20% of the 1000 CT scanner cases from the area in the past year were as a result of an accident emergency.
Dr Ballantyne said many of those using a CT scanner in Dunedin or Invercargill are elderly, and Central Otago with its ageing population is the best location for it.
