I. Introduction
Magnetic resonance imaging (MRI) is a medical imaging technique that is used to acquire images of internal organs and tissues, thus revealing the anatomy and the physiological processes of the body. It can provide images with higher pixel contrast compared to most other medical imaging techniques, by emphasizing tissue properties related to T1 and T2 relaxation times [1]. In order to do so, MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves. Contrarily to Computational Tomography (CT) techniques, it does not require the use of X-rays or other form of ionizing radiation, thus providing an important advantage for children, pregnant women, and patients who require repeated imaging procedures. MRI techniques produce medical images that have a high spatial resolution and a wide range of soft tissue contrasts, and is thusable to depict the body anatomy in great detail. Also, MRI techniques are able to generate images in more planes and can reconstruct organs and anatomical regions in 3 dimensions. In summary, MRI is one of the most important and non-invasive methods for visualizing internal biological tissues [2].
