Brain imaging is the use of modern technology to study structural anatomy, physiology, and metabolism of brain.
The evolution of modern brain imaging is synchronous with medical imaging with the discovery of X-ray in 1985 by German physicist Wilhelm Roentgen. It started with plain radiography of skull in different views and progressed with discovery of contrast agents and modification of X-ray technique for image acquisition. Radiographs taken after in vivo introduction of various contrast agents lead to development of pneumoencephalography, ventriculography, and angiography. Modification of X-ray technique with continuous stream of X-rays collected on an input screen after passing target organ allowed real time visualization of moving anatomical structures like a video called fluoroscopy.
