Abstract
Proton MRI of large biological samples were obtained on an 11.1 T /40 cm instrument. Images were obtained of a fixed human brain and a large piece of fresh beef. The proton MR images demonstrate severe distortions within these conductive samples, indicative of shortened electrical wavelengths and wave behavior within the sample. These observations have significant implications with respect to the continuing evolution of MR to higher magnetic field strengths on large samples, particularly on humans.
