The lateral prefrontal cortex is a region of interest because those who have injuries to that part of the brain often have issues with common, everyday tasks such as planning their day. The LPFC is thought to be important for "cognitive control capacity," which can be used to predict future outcomes such as success in school and the workplace.
The CT scan was introduced in the 1970s and quickly became one of the most widely used methods of imaging. A CT scan can be performed in under a second and produce rapid results for clinicians, with its ease of use leading to an increase in CT scans performed in the United States from 3 million in 1980 to 62 million in 2007.
Cranial ultrasound is a technique for scanning the brain using high-frequency sound waves. It is used almost exclusively in babies because their fontanelle (the soft spot on the skull) provides an "acoustic window".

The brain's magnetic field, measuring at 10 femto tesla (fT) for cortical activity and 10 3 fT for the human alpha rhythm, is considerably smaller than the ambient magnetic noise in an urban environment, which is on the order of 10 8 fT or 0.1 μT. The essential problem of biomagnetism is, thus, the weakness of the signal relative to the ...
[1] [5] [6] Some consider that the abnormalities need to be shown to be reversible. [4] [5] If lumbar puncture is performed this may show increased protein levels but no white blood cells. [1] [3] [4] Computed tomography scanning may be performed in the first instance; this may show low density white matter areas in the posterior lobes. [4]
