=== X-ray ===
In the year of 1895, Wilhelm Roentgen developed the first radiograph, more commonly known as the [[X-ray]].<ref name=":02">{{Cite web |title=History of Neuroimaging {{!}} The American Society of Neuroimaging |url=https://www.asnweb.org/i4a/pages/index.cfm?pageid=3334 |access-date=2023-10-04 |website=www.asnweb.org}}</ref> By 1901, Roentgen had been awarded a Nobel Peace Prize for his discovery. Immediately after its release, X-ray machines were being manufactured and used worldwide in medicine.<ref name=":1">{{Cite journal |last=Shorvon |first=Simon D. |date=March 2009 |title=A history of neuroimaging in epilepsy 1909–2009 |journal=Epilepsia |language=en |volume=50 |issue=s3 |pages=39–49 |doi=10.1111/j.1528-1167.2009.02038.x |issn=0013-9580|doi-access=free |pmid=19298431 }}</ref> The brain is almost entirely composed of soft tissue that is not radio-opaque, meaning it remains essentially invisible to ordinary or plain X-ray examinations. This is also true of most brain abnormalities, though there are exceptions. For example, a calcified tumor (e.g.,[[meningioma]], [[craniopharyngioma]], and some types of [[glioma]]) can easily be seen.
