Answer:
Magnetic resonance imaging (MRI)
Step-by-step explanation:
Magnetic Resonance Imaging is one of the most widely performed exams in the world at the most modern medical centers and has revolutionized the diagnosis, used in virtually all medical specialties and for patients of all ages, even babies.
It is an exam that does not use radiation, but acquires the information provided by the magnetic field and radiofrequency waves generated by the machine and translated by a special computer. Every day new and better techniques are launched creating detailed images for disease research and treatment follow-up. In short, magnetic resonance imaging is a procedure where a patient is placed within a magnetic field so that a computer can create three-dimensional images of his brain, or other body part that needs to be examined.
