EANM/ESC guidelines for radionuclide imaging of cardiac function
... Level A is rarely available for diagnostic imaging and level B sometimes; hence, level C is most often applied. In the present guidelines, emphasis has been laid on the presentation of evidence-based data with direct references to original papers. Clinical indications may often depend on several loc ...

Nuclear medicine
Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine scans are usually conducted by radiographers. Nuclear medicine, in a sense, is ""radiology done inside out"" or ""endoradiology"" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays.
