Study Notes
António Egas Moniz
- Highly regarded Portuguese neurologist
- Pioneered brain imaging research
- Developed frontal lobotomy procedure
- Invented the angiogram (1927)
- Angiogram: type of X-ray for checking blood vessels
- Used to locate brain tumors
- Injected radiopaque dyes to visualize blood vessels
- 25% sodium iodine used for clarity during angiograms
- Considered a pioneer in psychosurgery
- Believed he could treat mental illnesses like depression, anxiety, and schizophrenia with frontal lobotomies
- Used a needle with a wire loop (leucotome) to sever connections between frontal lobes
- Lobotomies were widely used in the US until the 1960s
- Results varied, only one-third of treated patients benefited, others harmed
- Received Nobel Prize in Physiology or Medicine (1949) for the invention of prefrontal lobotomy
- Published first paper on angiography in 1927
- Began experimenting on vascular imaging in 1902
