Malignant tumors can be fought with X-rays – usually with radiation therapy from outside the body. Nuclear medicine physicians can also accomplish this inside the body with radioactive materials, called radiopharmaceuticals. They also offer big benefits for clinical diagnostics as long as a specific target can be assigned to them.
Nuclear medicine physicians use so-called gamma cameras for myocardial perfusion scintigraphy. The devices record radioactive substances that are injected into the patient and show changes in the heart muscle (myocardium). Now a new gamma camera is able to record images faster and by using much less radiation.
Endoradiotherapy can be very unpleasant for cancer patients, since it does not only harm tumor cells, but also healthy ones. Sometimes, patients even need to stop therapy because of the side effects. Physicians and researchers are thus continuously searching for ways to transport radiopharmaceuticals directly and exclusively to their target.
