A new state of the art MRI scanner is set to result in better outcomes for patients in Adelaide's north-east.

The first of its kind in the southern hemisphere, the multi-million dollar machine will provide clearer images for medical specialists working at Modbury Hospital.

"It is very exciting for Modbury, it's part of a major upgrade to make sure it continues to deliver for the people of the northeast," Health Minister Stephen Wade said.

In the past, the hospital wasn't equipped with an MRI machine, forcing patients to travel to other hospitals across Adelaide to undergo scans.

Rosemary Bruhn received treatment for a stroke at Modbury Hospital - she says the new technology will help reduce anxiety and stress.

"I had to go out to Salisbury which was about a 20-30 minute drive in a car and with a nurse."

The Health Minister said the investment symbolises the renewal of the hospital, claiming the facility was downgraded under the former Labor government's transforming health plan.

Doctors expect the emergency department will benefit most from the technology upgrade.
