Nuclear Magnetic Resonance Tomography of the Brain

摘要: Abstract Nuclear magnetic resonance (NMR) has long promised to provide a risk-tree alternative method for both structural and functional tomography of the human body, since original small scale demonstration its principles by Lauterbur. The considerable technical problems involved in scaling up successful 8 cm diameter line-scan NMR imaging apparatus have been overcome, 128 · element tomograms electronically definable planes less than 1 thick through living brain can be produced routinely total times 2.5 min. used is briefly described, it compared with radionuclide emission tomography, which most resembles. contrast mechanism images hazard are also discussed.
