title: Effect of food intake on liver and spleen volume: assessment with single photon emission computed tomography.
abstract: OBJECTIVE
  The authors evaluated the influence of food intake on liver and spleen size. The rationale was that since a meal induces a marked increase in splanchnic blood flow, organ volume might also be affected. This could influence conclusions made at clinical examination.
  
  
  METHODS
  Single photon emission computed tomography (SPECT) was performed in 20 healthy volunteers after administration of technetium-99m albumin colloid before and after ingestion of a standardized meal. A semiautomatic technique was used to determine liver and spleen size.
  
  
  RESULTS
  There was a nonsignificant reduction in liver volume of 1.5% (P = .063) and a significant reduction in spleen volume of 3.2% (P = .00033) after food intake.
  
  
  CONCLUSIONS
  Liver and spleen volume are marginally affected by food intake, and the changes are within the methodologic error of radiologic modalities.
