About us

Professor Thomas Krause, M.D. is director and chief surgeon of the University Department of Nuclear Medicine at the Inselspital Hospital Bern. As an expert in nuclear medicine, Prof. Krause’s areas of clinical emphasis mainly focus on the administration of radioactive substances and nuclear physics-based methods for the medical diagnosis and therapy as well as the radiation protection with its medical, physical and biological fundamentals.

As part of the diagnostics, the expert in nuclear medicine Prof. Krause in Bern performs nuclear medical examinations for functional and localisation diagnostics. Functional diagnostics is aimed to review and access the function of organs, organ systems and of tissue, such as the thyroid, the kidneys, the heart or bone. These techniques allow experts in nuclear medicine like Prof. Krause in Bern to diagnose diseases and functional disorders of the examined organs and tissues at a very early point in time. Localisation diagnostics are aimed to determine the exact position of a pathological process, like a tumour, for example.

Prof. Krause and his team of experts at the University Department of Nuclear Medicine in Bern provide the entire spectrum of nuclear medicine-based examinations utilizing state-of-the-art methods and devices, all based on evidence-based medicine. The types of examinations performed by the nuclear medicine expert Prof. Krause and his team in Bern particularly include scintigraphy, positron emission tomography (PET) and single-photon emission computer tomography (SPECT).

These nuclear medical studies involve imaging procedures used to visualize on images the various bodily functions like metabolic pathways or circulation for example, following administration of extremely low doses of radioactive substances. The radioactive substances - contrast media - are usually injected into an arm vein. But they can also be inhaled via an inhalation device or swallowed as liquid or capsule.

The subsequently taken two-dimensional images (scintigrams) and/or cross-sectional images (SPECT/CT or PET/CT) show the distribution of the contrast media in the body, thereby enabling the nuclear medicine expert Prof. Krause in Bern to draw conclusions about the functionality of the examined organs and body regions. Using these methods, the expert in nuclear medicine Prof. Krause in Bern examines, among others, organs like the thyroid (by thyroid scintigraphy), the kidneys (by renal function scintigraphy), liver (by liver scintigraphy) and the heart (by myocardial# scintigraphy).

Within the scope of his nuclear medical therapeutic methods, the expert in nuclear medicine Prof. Krause in Bern also employs radioactive medicinal agents to treat patients with benign and malignant diseases like cancer, metastases, thyroid nodules, hyperthyroidism or hypothyroidism. Some of the therapeutic areas of emphasis of the expert in nuclear medicine Prof. Krause in Bern, for instance, include radioiodine therapy to treat diseases and functional disorders of thyroid, selective internal radiotherapy (SIRT) to treat benign liver tumours and liver metastases, radioimmune therapy to treat malignant lymphoma, DOTATATE therapy to treat neuroendocrine tumours and pain therapy for bone metastases (e.g. Alphardin).

Whenever possible, Prof. Krause and his team of experts carry out their nuclear medical treatments on an outpatient basis. In some cases, however, a hospital stay is mandated. For such cases, the University Department of Nuclear Medicine in Bern has been equipped since January 2012 with a state-of-the-art therapy ward consisting of a total of four single rooms as well as three spacious rooms each with 2 beds.

The therapy ward of the University Department of Nuclear Medicine in Bern under the direction of the nuclear medicine expert Prof. Krause unites the excellence of nuclear medicine and care with the infrastructure required to perform both the conventional and modern therapeutic methods offered by nuclear medicine. In this way, the facilities and measuring instruments at the University Department of Nuclear Medicine in Bern are optimally suited for the treatment and monitoring of benign and malignant diseases of the thyroid and other organs. Besides this, the expert  in nuclear medicine and his team at the Inselspital Bern can now also perform the more modern methods of tumour and pain therapy that previously were only available at a few centres.
