Brain Magnetic Resonance Imaging to Solve Intricate Puzzles Of The Brain

Magnetic resonance imaging (MRI) is a noninvasive medical test that uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed images of organs, soft tissues, bone and virtually all other internal body structures to help doctors diagnose and treat medical conditions. Ionizing radiation is not used for Magnetic resonance imaging. Using these detailed images, physicians are able to better evaluate various parts of the body. Magnetic resonance imaging enables doctors in determining the presence of certain diseases that cannot be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography. Currently, MRI is considered to be the most sensitive imaging test of the head.

Brain magnetic resonance imaging is performed to help diagnose tumors of the brain and developmental anomalies of the brain. Physicians conduct the MR examination to document brain abnormalities in patients with dementia. MRI of the head allows doctors to find vascular anomalies of the head, disorders of the eyes and the inner ear, stroke, disease in the pituitary gland, and certain chronic disorders of the nervous system, such as multiple sclerosis.

Functional MRI of the brain (fMRI) is the latest technique used to identify important language and movement control areas in the brain in patients who are being considered for brain surgery.

For brain magnetic resonance imaging, the MRI unit that is used is a large cylinder-shaped tube surrounded by a circular magnet. The patient lies on a moveable examination table that slides into the center of the magnet. Open MRI units are also available to provide very high quality images for conducting many types of exams.
