Abstract
Clinical images are worthwhile in Health Sciences and their analysis and correct interpretation aid the professionals,such as physicians, physiotherapists and occupational therapists, to make decisions and take subsequent therapeutic and/or rehabilitation measures. Other factors, besides the state of the disease, may interfere and affect the bioavailability of the radiopharmaceuticals (radiobiocomplexes) and the quality of the SPECT and PET images. Furthermore, the labeling of some of these radiobiocomplexes, such as plasma proteins, white blood cells and red blood cells, with 99mT, can also be modified. These factors include drugs (synthetic and natural) and dietary conditions, as well as some medical procedures (invasive or non-invasive), such as radiation therapy, surgical procedures, prostheses, cardioversion, intubation, chemoperfusion, external massage, immunotherapy, blood transfusion and hemodialysis. In conclusion, the knowledge about these factors capable of interfering with the bioavailability of the radiobiocomplexes is worthwhile for secure diagnosis. Moreover, the development of biological models to study these phenomena is highly relevant and desirable. Imagens clínicas são valiosas em Ciências da Saúde e a análise e a interpretação correta das mesmas auxiliam os profissionais, como médico, fisioterapeuta, terapeuta ocupacional, na tomada de decisões e subseqüentes ações terapêuticas e/ou de reabilitação. Além das doenças outros fatores podem interferir e afetar a biodisponibilidade dos radiofármacos (radiobiocomplexos) e a qualidade das imagens (SPECT e PET). Além disso, a marcação de alguns desses radiobiocomplexos com Tc-99m, como proteínas plasmáticas, leucócitos e hemácias, também pode ser modificada. Entre esses fatores, estão drogas (sintéticas e naturais) e condições alimentares, assim como alguns procedimentos médicos (invasivos e não invasivos), como a radioterapia, processos cirúrgicos, próteses, cardioversão, intubação, quimioperfusão, massagem externa, imunoterapia, transfusão sanguínea e hemodiálise. Em conclusão, o conhecimento sobre esses efeitos capazes de interferir na biodisponibilidade de radiobiocomplexos é altamente relevante para diagnósticos precisos. Além disso, o desenvolvimento de modelos biológicos para estudar esses fenômenos é de elevada importância e desejávelKeywords
