ABSTRACT

Introduction: The study of the positron emission tomography together with computed tomography with fludeoxyglucose F 18 has been revealed as the "gold standard" minimally invasive study for the diagnosis, assessment and follow-up of a wide range of oncological diseases. Methods: Bibliographic review on the main indications, contraindications, causes of false positives or false negatives and of the most important limitations of the procedure. We broadly explain the preparation and behavior the patient must complete before, during and after the examination for its satisfactory performance are widely explained, the characteristics of the different stages of the acquisition of images, as well as the general dosimetric characteristics that each of them possesses and that must be taken into account to ensure compliance with the principles of radiological protection in the medical practice. We go deeply into details regarding the processing, quantification and interpretation of the images, as well as into the importance for this step of knowing the patient's clinical history, which together with the experience of the multidisciplinary professional group allows to guarantee the adequate evaluation of the changes occurring at the molecular level and that are the basis of the diagnostic efficiency of this technology. Conclusions: The study of positron emission tomography together with computed tomography with fludeoxyglucose F 18 plays an important role in the management of oncological disease. It is an effective study, but requires special conditions for the preparation of the patient and the development of the study, as well as the integration of a multidisciplinary group of highly-qualified specialists.
