Claraspital Nuclear Medicine is a specialised tumour diagnostics centre with a complete diagnostic spectrum of nuclear medicine including PET examinations and combined PET/CT examinations.
Great at recognising the smallest changes
Nuclear medicine methods are used to measure the function of an organ, to visualise blood flow or to detect structures with altered metabolism such as tumours, metastases or centres of inflammation. They also provide information on the success of chemotherapy or radiotherapy.
The nuclear medicine department at the Claraspital has state-of-the-art equipment for this purpose. The detectors of the new devices have an even higher sensitivity, which improves the accuracy of the diagnosis and at the same time makes it possible to reduce the dose of radiopharmaceuticals. This further reduces the radiation exposure for patients, making the examination even gentler.
Various procedures are used at the Claraspital. The basic principle is the same: radioactively labelled substances are administered intravenously. They concentrate at the points inside the body where the most energy is consumed. Using a special camera, tiny amounts of radioactivity are measured, converted into an image by a high-performance computer and visualised.
«We are a specialised tumour diagnostics centre. PET positron emission tomography provides us with cross-sectional images of the body. With the PET-CT device, a combination of PET and computer tomography, we can, for example, identify the exact position, size, activity and spread of a tumour.»

Cardiac examination using rubidium PET/CT
If a circulatory disorder of the heart muscle is suspected, nuclear medicine makes a decisive contribution to the diagnosis. "We show how the heart, blood vessels and blood behave under normal conditions and under a simulated stress situation," explains PD Dr Kwadwo Antwi, Head of Nuclear Medicine at the Claraspital. Claraspital Nuclear Medicine offers the examination of the heart muscle using rubidium PET/CT.
"The added value of this method for our patients is very high," explains Kwadwo Antwi. "On the one hand, this is thanks to the extremely short half-life of rubidium of 1.27 minutes, which reduces the radiation exposure for patients by around 85 per cent." The entire examination at rest and under simulated stress thus takes just 30 minutes - instead of the four hours spread over two days using conventional methods. "On the other hand, the dynamic functional visualisation of blood flow offers us improved image quality and a higher spatial resolution, so that we can interpret the images even better."
