Abstract

The position and composition of organs affect the field (B₀) homogeneity of magnetic resonance imaging. B₀ inhomogeneities can impact image quality. The effects of three breathhold positions (deep inhalation, shallow inhalation, and exhalation) on B₀ homogeneity were measured at 3 T in the abdomens of 13 healthy volunteers. B₀ maps were acquired using a breathheld phase mapping sequence and converted into a center frequency offset (Δf). B₀ was evaluated quantitatively in three regions of interest (ROIs): the liver, left kidney, and right kidney. In general, the mean B₀ frequency offsets (<Δf>) in the ROIs were highest during deep inhalation and lowest in exhalation.
