In contrast to neuroimaging, neuroradiology is qualitative (based on subjective impressions and extensive clinical training) but sometimes uses basic quantitative methods. Functional brain imaging techniques, such as functional magnetic resonance imaging , are common in neuroimaging but rarely used in neuroradiology. Neuroimaging falls into two ...
The scan tests for consistent and sufficient blood flow to all areas of the brain by having patients breathe in xenon gas, a contrast agent, to show the areas of high and low blood flow. Although many trial scans and tests were ran during the development process of computed tomography, British biomedical engineer Godfrey Hounsfield is the ...
In 2004, scientists at the Center for Bioinformatics Space Life Sciences at the NASA Ames Research Center examined Peek with a series of tests including computed tomography (CT scan) and magnetic resonance imaging (MRI). The intent was to create a three-dimensional view of his brain structure and to compare the images to MRI scans performed in ...
A new study used MRIs to observe what happened when grandmas saw pictures of their grandkids. The brain scans reveal what grandmothers already know to be true.

Researchers said the findings, based on brain scans from one mother, may represent one of the first comprehensive maps of changes in the organ before, during and after human pregnancy.
Activation locations detected by BOLD fMRI in cortical areas (brain surface regions) are known to tally with CBF-based functional maps from PET scans. Some regions just a few millimeters in size, such as the lateral geniculate nucleus (LGN) of the thalamus, which relays visual inputs from the retina to the visual cortex, have been shown to ...
Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. . Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's brain activit
