Although the lack of vocalization when speaking or partial paralysis can simply be signs of an attack or a migraine, they can also be symptoms of a stroke. Cerebral infarctions are the third leading cause of death in the United States and one of the leading causes of severe disability.
More than 3 million people who have survived a stroke have become unable to work or take care of themselves. For this reason, when a patient enters an emergency room with these symptoms, doctors must make a crucial diagnosis without losing a second. Although the number is still small, there are more and more hospitals that can perform ultrasound MRI of the patient's brain using a technique called functional magnetic resonance.
In just a few minutes, the scanner reveals not only if the patient has suffered a stroke but also which part of the brain is at risk. The urgency of this diagnosis should not be underestimated. As one neurologist once said, "Time is brain. The earlier the diagnosis is made and treatment begin, the greater the part of the brain that can be saved."
This tool for the diagnosis of cerebral infarctions represents the first important clinical application of functional magnetic resonance imaging. Since the early 1990s, functional magnetic resonance imaging has helped neurology researchers learn more about brain functioning, as it allows them to observe the changes that occur in the chemical composition of different areas, as well as changes that occur in the circulation of fluids in a matter of seconds or minutes. Functional magnetic resonance imaging can also be used to better understand the physiology of other organs.
Conventional magnetic resonance imaging by MRI test labs in Delhi which provides detailed images of the anatomical structure, also plays an essential role in observing other parts of the body. It allows to detect symptoms of arterial sclerosis in the heart, as well as herniated discs, broken cartilage and tumors in the spine, bones, and joints. In all these cases, magnetic resonance imaging is performed without the need for painful interventions.
The basic investigations that led to magnetic resonance and functional magnetic resonance began in a series of physics laboratories in the first decades of the 19th century. This article describes the path, often tortuous, that has been traveled during the last 70 years from the work of a series of scientists who simply investigated the nature of matter to current applications that ultimately save many lives.
The images of the human brain obtained by functional magnetic resonance represent the most recent advance in a field that was born just 20 years ago. Currently, scientists use functional magnetic resonance imaging to study the changes that occur in the brain activity of patients who have suffered a stroke and who begin to recover lost skills, with the aim of developing more effective treatments and therapies.
The functional magnetic resonance imaging allows investigating the development of the neural networks of the motor, visual, auditory, and speech systems of a baby when listening to the voice of his mother. MRI done by MRI scan center in New Delhi can also help to understand the subtle abnormalities in the activation of the brain in children with problems of lack of attention due to hyperactivity and memory problems of patients with schizophrenia.
