A new CT unit was opened at Mercy University Hospital Cork today by Minister for Agriculture Simon Coveney.
€1m was raised in donations over the last three years to fund the new equipment which cost €2.5m.
Almost 10,000 CT scans are carried out at the hospital every year.
The hospital said the introduction of the scanners would improve the services and care offered to patients.
Dr Martin O'Driscoll, Consultant Radiologist at the hospital said: "Our new 128 and 16 slice state-of-the-art scanners, housed in a purpose built facility, allows us to optimise our ability to image the body."
"The scanners will allow us to scan patients with higher resolution, shorter scan times and minimal radiation dose," he said.
