In 2021, the University Hospital Zurich (USZ) put the world's first photon counting CT into operation at the campus in the center. The first device of the next generation, a single-photon counting CT, has recently been installed at the USZ Airport site. This means that patients in outpatient care also benefit from the advantages of this imaging procedure.
In contrast to conventional computer tomography (CT) scanners, photon counting technology converts individual X-rays directly into electrical signals without any loss of information. The result is significantly sharper images with higher contrast and more diagnostic details - allowing the finest structures in bones or tissue to be recognized that are only blurred or not visible at all with other types of CT devices. This level of detail supports the clarification of cardiovascular diseases, lung diseases, abdominal findings and musculoskeletal problems in particular. Patients with neurological diseases can also receive better care thanks to the significantly improved imaging. For patients, this means- More precise diagnoses: early stages of tumors, vascular changes or lung diseases can be better detected. In many cases, an invasive examination - such as a cardiac catheterization - can be avoided.
- Less exposure: The radiation dose can be reduced by up to 40 %, as can the use of contrast agents. This is particularly important for younger patients and for people with impaired kidney function.
- Faster results: AI-supported processes and automated image analysis shorten the time to diagnosis - a benefit for referring physicians and patients.
- More information: Each examination provides additional spectral data that allows conclusions to be drawn about tissue composition and disease processes - this information supports the selection of the most effective individual therapy.
