At the University Hospital Leipzig, the previously decentralised nuclear medicine department is being centralised in a new building section. The new build is being constructed as an extension to the existing Building 3 and consolidates the functions currently distributed across various buildings – including the inpatient ward with hot lab and cyclotron as well as diagnostic and outpatient units – in one location. This structural bundling enables optimised workflows in diagnostics, therapy, and logistics, especially regarding the production and internal transport of radiopharmaceuticals. At the same time, patient and medical staff routes are significantly shortened.
The new clinic building is primarily used for the production and application of radiopharmaceuticals as well as for the treatment of oncological diseases. It comprises, among others, a GMP-compliant hot lab area, a cyclotron, a whole-body counting area, a thyroid outpatient clinic, an inpatient therapy unit, as well as various service and ancillary rooms. Special emphasis in the planning is placed on high radiation protection, clear functional separation of sensitive areas, and integration into the established University Hospital infra-structure. The design also takes future expansions into account to ensure long-term usability.
ZWP is commissioned with the planning and site supervision of the technical building services.Integration into the existing hospital structure poses special requirements for technical planning. The new build’s systems will be connected to the University Hospital’s central supply networks for heating and cooling. A specialised decay system based on a BioChroma system is planned for the treatment of radioactive wastewater. The ventilation supply is provided via three central systems with a total air volume of around 45,000 cubic metres per hour.
Technical requirements in radiation protection additionally require the planning of pressurisation systems for radioactive exhaust air from radiopharmaceutical production. This exhaust air is fed into special interim storage facilities to ensure a controlled decay time before release into the environment. An exhaust air system with activated carbon filtration is planned for the therapy ward. Furthermore, ZWP plans the central supply of laboratory and special gases, including a comprehensive emergency management system. Another key component is exhaust air and room monitoring, which continuously monitors any potentially occurring radioactive contamination as well as air cleanliness classes according to the requirements of Good Manufacturing Practice (GMP).
ZWP ensures that not only all technical systems comply with the applicable regulatory and medical requirements, but are also operated flexibly, sustainably, and future-proof, thereby significantly contributing to the functionality, safety, and performance of the new Centre for Nuclear Medicine at the University Hospital Leipzig.
