Why Choose the Charité?

The Charité is the largest university hospital in Germany and one of the most renowned hospitals in the world. Treatment in a large hospital offers several advantages: it is convenient for a patient because all diagnostic and interventional procedures are available in a single location, the interventional radiologists work closely with other clinical specialists (e.g., surgeons and oncologists), and all radiologists are highly experienced and particularly qualified for the procedures they perform. We can therefore provide the treatment best suited for each patient and his or her clinical condition.


Unlike in other, non-university hospitals, our radiologists are also involved in the scientific investigation and improvement of the procedures they perform on patients. As scientists, they constantly analyze minimally invasive interventions and outcomes, aiming to improve and advance their techniques in accordance with new scientific insights and developments.

What is Minimally Invasive Tumor Therapy?


It has always been the aim of medical treatment to cure a patient as quickly as possible and with minimum discomfort. Many new treatments already use what is known as keyhole surgery. Instead of scalpels, radiologists use imaging techniques and very small instruments to treat tumors. The instruments are introduced into the body through the skin or through the blood vessels. Only very small cuts are needed to insert these instruments and position them at the site of treatment. Some minimally invasive procedures can be performed in an outpatient setting (such as the implantation of venous catheters like indwelling ports, PICCs, or CVCs), while others may require a short stay at the hospital. Hospital stays and time away from work are much shorter than with more conventional treatments.


Our department has many years of experience with minimally invasive medical procedures. Over the years, we have received an increasing number of inquiries from patients wishing to know more about these types of examinations and treatments.


Each year, our department performs over 2000 minimally invasive diagnostic and therapeutic interventions, ranging from tissue sampling to the treatment of malignant tumors.


We deliberately offer a spectrum of different minimally invasive treatment options (especially for the treatment of liver tumors) in order to be able to choose the most appropriate therapeutic strategy for each patient’s unique situation. Some minimally invasive procedures have been developed or improved by interventional radiologists of our department.


Our interventional radiologists perform minimally invasive interventions using the latest imaging techniques (including computed tomography, angiography, magnetic resonance imaging, ultrasound, and projection radiography) for guidance. Depending on the type of procedure, the images can be processed on specialized workstations to generate a 3D display or for detailed treatment planning (e.g., calculation of radiation doses for radiotherapy). These imaging techniques not only provide diagnostic information but also help the radiologist to plan the therapeutic approach and to ensure safe navigation and maneuvering of the instruments during the diagnostic or therapeutic procedure.


As a result of the large number of image-guided procedures performed in our department, our interventional radiologists are highly skilled and have extensive experience in their field.


With a team of over ten interventional radiologists, the Department of Radiology of the Charité offers special expertise in different areas of minimally invasive tumor treatment.


Moreover, image-guided minimally invasive therapy is a focus of special interest in our department. To meet the special needs of our patients, we offer specialized outpatient services and a dedicated ward for our patients undergoing minimally invasive procedures or therapies.


Before each image-guided minimally invasive treatment, our radiologists make a careful assessment and discuss details of the planned procedure with you. This is done to ensure that you are a suitable candidate for the procedure, to find out whether an alternative treatment might be more appropriate, and to rule out contraindications (i.e., factors suggesting that you should not have a particular procedure). Moreover, you will be given comprehensive information on how the treatment is performed, including chances of success and possible risks.


This website provides general information on the different types of minimally invasive procedures that are offered by our department.
