New CT Scanner Increases Diagnostic Capacity at Kenepuru Hospital
The Photon Counting Computed Tomography scanner introduced at Kenepuru Hospital last month is delivering early benefits for patients in Porirua and nearby areas, according to Health Minister Simeon Brown.
He said the technology is providing quicker, more precise, and highly detailed diagnostic imaging, which is supporting timely care within the community. He noted that 245 patients have been scanned in the first four weeks and that CT outpatient activity across Wellington and Kenepuru has risen by 37 percent.
Early Clinical Impact
The scanner has been operating since 14 October. During this period, advanced imaging has identified conditions that were previously undetectable. Some patients have avoided invasive procedures that would have been required earlier. Improved vascular imaging has also helped inpatients leave the hospital up to a week sooner.
The availability of on-site imaging has reduced ambulance transfers and transit nursing between Wellington and Kenepuru hospitals, which is supporting workflow improvements and creating additional capacity.
Diagnostic Improvements
Since commissioning, the scanner has confirmed diagnoses for 20 patients, removing the need for further testing. In addition, 18 cardiac patients who would previously have required invasive angiography were able to undergo non-invasive CT coronary angiograms instead, representing a 90 percent rise in non-invasive cardiac imaging.
Simeon Brown said the clarity of the imaging is comparable to a shift from black-and-white television to Ultra-HD. He stated that more detailed, diagnostic images are allowing earlier treatment and shorter hospital stays, while supporting clinicians in managing patients with complex needs.
Future Service Expansion
Plans are being developed to increase access to diagnostic services beyond the hospital. This includes a community-based service at Kenepuru and a trial in collaboration with local general practices.
The minister said the early results demonstrate how this technology can support patients and the wider health system by improving outcomes, easing hospital pressure, and enhancing access to care in Porirua and surrounding communities.
