Technological advances in science and today’s rapidly changing healthcare environment, driven by demographic change and high economic pressures on healthcare systems, requiring disease diagnoses with high accuracy and specificity in a short period of time, implies that Magnetic Resonance Imaging must adapt to these challenges, as well as updating new approaches, This means that the Magnetic Resonance Imaging technique must adapt to these challenges, as well as the updating of new approaches, updated on Physical Principles, Human Anatomy and Radiological Semiology, in the theoretical-practical skills in the performance of technologists, related to the procedure of the Magnetic Resonance Imaging technique, which demands the need to scientifically validate a proposal for the training of the health technologist in Magnetic Resonance Imaging in its technological procedure. Objective: The objective of the present work is to scientifically validate a proposal for the training of the technologist in the technological procedure in Magnetic Resonance Imaging in Health Sciences. Methods: Methods of the theoretical level such as the synthetic analytical, of the empirical level the observation and of the mathematical statistical level the statistical analysis of the methods used, the Expert criterion, with the Delphi method were applied. These methods made it possible to propose the needs of the Technologist in the technological procedure for his training in Magnetic Resonance Imaging. The proposal was scientifically assessed by experts by means of the Delphi method and was applied to the technologists of the Provincial Hospital of Cienfuegos, Cuba. Results: The scientific validation is evidenced, through the Delhi Method and Expert Criteria, of the proposal for the training of the Technologist in the technological procedure in Magnetic Resonance Imaging, for medical health. The updating of the contents on the Physical Principles, Human Anatomy and signs of Radiological Semiology, through theoretical and practical workshops in the workplace, stands out. Conclusions: The proposal was validated as very adequate by the experts and its application in the context of Secondary Health Care demonstrated its relevance. It is considered that in the training of the Technologist, the technological procedure for Magnetic Resonance Imaging requires the updating of Physical Principles, Human Anatomy and signs of Radiological Semiology
