Magnetic Resonance Imaging of a Human Brain

Magnetic Resonance Imaging of a Human Brain




Magnetic resonance imaging (MRI) is a procedure used to acquire precise images of the human body. With magnetic resonance imaging of the human brain, the complete functioning of the brain can be observed by visuals and images.

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 progressive techniques of functional MRI, it is possible to understand more about the composite structure of the brain and its roles. The MRI technology known as perfusion used in brain scans, already helps to detect strokes in the beginning stages itself, consequently enabling the patient to be treated effectively at an early stage.

The main techniques involved in functional MRI are spread tensor imaging, magnetic resonance spectroscopy and blood oxygenation level-dependent imaging. With these inventive processes, it is also possible to clarify 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 quantity. With MRI, the variations in blood oxygenation can be recognized by the gradient echo (GE) imaging series. Another course of action, 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 appropriate 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 complicate structure of the brain, MRI makes use of a magnetic field, radio groups and a computer. The complete course of action of scanning is painless. Magnetic resonance imaging is considered a safe procedure that is totally free from side effects as there is no radiation.
