Magnetic Resonance Imaging of Human Brain
Magnetic resonance imaging (MRI) is a procedure used to obtain precise images of the human body.
An Easy Method to Diagnose the Abnormalities of the Brain
Magnetic resonance imaging technique for analyzing the activities of the human brain has proved to be of great importance in the field of neurology. By using advanced techniques of functional MRI, it is possible to understand more about the composite structure of the brain and its functions. The MRI technology known as perfusion used in brain scans, even helps to detect strokes in the beginning stages itself, thus enabling the patient to be treated effectively at an early stage.
The main techniques involved in functional MRI are diffusion tensor imaging, magnetic resonance spectroscopy and blood oxygenation level-dependent imaging. With these innovative processes, it is also possible to identify the injuries and other variations affecting the functioning of the brain. In human beings, neural motions affect the cerebral flow of blood, blood oxygenation and blood volume. With MRI, the variations in blood oxygenation can be recognized through the gradient echo (GE) imaging series. Another process, the spin-echo inversion recovery (IR) is used to analyze the variations in the flow of blood. By using these two procedures, it is possible to receive images of the brain incessantly at equal pulse progressions.
Magnetic resonance imaging is not suitable for those persons who have metal implants in their body including pacemakers and metal chips, as the magnetic effect can cause a shift in the metal in the related areas of the body. It can also alter the scanned images to a great extent.
Safe Technology without Side Effects
In order to develop a precise image of the complex structure of the brain, MRI makes use of a magnetic field, radio waves and a computer. The entire process of scanning is painless. Magnetic resonance imaging is considered a safe procedure that is totally free from side effects as there is no radiation.
