Brain Stroke And Its EffectsStroke is the third leading cause of death and long term disability. It causes around 140k people to die each year. A stroke happens when blood flow to the brain is interrupted by either a broken blood vessel or a block. Blood flow ensures a constant supply of oxygen to the brain cells. When the blood flow stops, cells will no longer receive oxygen and the cells will die. A stroke will need a brain scan to be diagnosed which will have varying MRI brain cost in Chennai. There are two types of hemorrhagic stroke and Ischemic stroke. When the blood vessel in the brain disrupts and causes blood leak in the brain, it is called a hemorrhagic stroke. When the blood vessel to the brain is blocked, it will lead to ischemic stroke. A brain stroke will have several symptoms. A stroke will lead to severe headaches. There will be weakness and numbness of the leg, arm or face. You will have understanding speech or have trouble speaking. You will have issues with your vision in one or both the eyes. You will have issues with coordination, balance and even dizziness. MRI Brain Scan For Diagnosing Brain StrokeA radiologist from the leading and best MRI scan centre in Chennai explains the importance of MRI scan for diagnosing and monitoring brain strokes. The first step in the assessment is to identify the type of stroke. MRI brain scan is the first test done to detect the damaged brain tissue which is damaged by a brain haemorrhage or ischemic stroke. An MRI scan is very effective in identifying specific lesions and pathologies that resemble an ischemic stroke. An MRI brain scan will be created in three orientations of the brain to provide a conclusive, clear and a 3D view. The three orientations are coronal, sagittal and axial. Different MRI sequences are used in one scan. Each sequence will highlight different aspects of brain tissues. This is particularly useful in identifying abnormalities within a few hours after ischemic stroke. Some of the commonly used MRI techniques are T1 weighted imaging, T2 weighted imaging, spin density-weighted imaging, gradient-echo imaging, and diffusion-weighted imaging. MRI Brain Scan For Monitoring Brain StrokeMRI is a valuable tool to evaluate and monitor the patient's progress once the stroke is treated. It is an effective test that can monitor the recovery of the tissues non invasively. A functional MRI scan of fMRI is the traditional way to monitor stroke recovery. A functional MRI can measure the progress of a patient who is undergoing stroke rehabilitation therapy. An fMRI is used to detect how effective the therapy training is in increasing the number of activated sensorimotor cortical voxels. It also can be used to identify the potential of inducing cortical plasticity in chronic stroke patients. MRI is an important test for diagnosing, treating, evaluating and monitoring stroke. Faster scanning with stronger magnets ensures that we get accurate results in emergencies. Read More : Emerging Technologies To Support A Mammogram In Chennai
