La imagen radioisotópica: una herramienta eficaz en la terapia regenerativa

[摘要] Regenerative therapy is nowadays a promising alternative treatment for many diseases. The utility of radioisotope image technologies in assessing of the efficiency and security of stem cell therapies is described. We present some of the facts that led to development of the nuclear medicine image technology, as well as the general characteristics of single photon emission computed tomography and positron emission tomography. It was also included application of radioisotope images in the evaluation of biodistribution changes, flow and perfusion in anatomical affected zones by different diseases, in the fields of angiology, orthopedia and cardiology, as a result of the regenerative and proliferative effects induced by stem cells transplant. We mention the radiopharmaceuticals and labelled molecules used in the evaluation of angiogenesis and lymph angiogenesis resulting of cellular therapy and the radioisotopes markers that allow tracking of transplanted stem cells.
