Brain imaging refers to various medical imaging techniques used to visualize the structure and function of the brain, including the brain's vascular system. Some of the major Neuroimaging  techniques that have revolutionized our understanding of the brain include magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), magnetic resonance angiography (MRA) and electroencephalography (EEG). Each technique provides a different view of the brain and has helped answer questions that were previously unanswerable.

Magnetic Resonance Imaging

Magnetic resonance imaging or MRI is one of the most widely used Neuroimaging techniques. MRI uses powerful magnets and radio waves to generate detailed images of the brain and its structures without using ionizing radiation. MRI produces high quality images that allow visualization of both abnormal and normal brain structures. It is very useful for detecting lesions, brain tumors, vascular malformations, degenerative changes and injuries in the brain. Advanced MRI techniques like fMRI, DTI and MRA have provided invaluable insights into brain function, connectivity and vascular morphology. MRI has transformed our understanding of brain development, aging and countless neurological and psychiatric disorders.
