In combination, the two imaging methods provide significantly more information about tumors. A variety of imaging procedures provide insights into the body's interior. Each has its special advantages, but also its limits.
In combination, the two imaging methods provide significantly more information about tumors. A variety of imaging procedures provide insights into the body's interior. Each has its special advantages, but also its limits. MRI enables doctors to differentiate between different tissues or to visualize the blood circulation. Neue bekanntschaften wien nrue of positron emission tomography PETon the other hand, lies in the imaging of specific cell or tissue functions: Weakly radioactively labelled biomolecules, the "tracers", are introduced into the metabolism and detected with high sensitivity in cells and tissues.
The physicist is therefore delighted that the DKFZ is now able to commission a worldwide unique combined device: It combines an MRI with an ultra-high magnetic field strength of 9. The DFKZ researchers want to single rostock important research projects neue bekanntschaften wien this way. Hypoxic tumor areas, for example, often prove to be particularly difficult to treat. The aim of the new scanner is to find out whether heavy ion radiation, for example with carbon particles, is superior to conventional photon therapy when treating bekanntschaft tirol resistant areas.
This has long been neue bekanntschaften wien because heavy ion radiation has a particularly high biological effectiveness. But this assumption has never been proven in the living organism. Using combined imaging, DKFZ researchers hope to compare the oxygen-poor areas before and after photon and wein ion therapy on tumor models.
A special PET tracer, which partnervermittlung online kostenlos indicates oxygen-poor tumor areas, helps here.
At the same time, MRI can be used to determine whether the blood flow through the tumor enables the tracer to penetrate these areas at all. Only the combination of both methods makes this examination useful at all. If the animals had to be carried back and forth between two examination devices, the images of the bekanntschaftn anatomical structures would never be perfectly congruent. Numerous other research projects will follow.
This will enable doctors to monitor the efficacy of cancer therapies in the future. At DKFZ, more than 1, scientists investigate how cancer develops, neue bekanntschaften wien cancer risk factors and neue bekanntschaften wien to find new strategies to prevent people from getting cancer.
They develop novel approaches to make tumor diagnosis more precise and treatment of cancer patients more successful. The staff of the Cancer Information Service KID offers information about the widespread disease of cancer for patients, their families, and the general public. Combining excellent bekanntschaftenn hospitals with high-profile research at a Helmholtz Center is an neue bekanntschaften wien contribution to frauen treffen zürich the chances of cancer patients.
