Ultrasonography successfully differentiates human morphotypes, revealing distinct liver shapes and positions. This study refines understanding of liver anatomy based on body type, moving beyond cadaver-based classifications.

Area of Science:

  • Anatomy
  • Medical Imaging
  • Anthropometry

Background:

  • Liver shape and position are influenced by body morphotype.
  • Traditional morphotype classification relied on cadaver observations.
  • Modern ultrasonography offers a non-invasive method for anatomical assessment.

Purpose of the Study:

  • To classify human morphotypes using ultrasonographic parameters.
  • To compare ultrasonographic findings with traditional anatomical classifications.
  • To investigate the relationship between morphotype and liver topography.

Main Methods:

  • Seventy-four healthy adults were assessed using ultrasonography.
  • Key parameters included hepatic diameters, xiphoid angle, and liver orientation.
  • Discriminant analysis was employed to differentiate morphotypes.

Main Results:

  • Three distinct morphotypes (breviligne, longiligne, normotype) were identified ultrasonographically.
  • Significant differences were found between ultrasonographic and traditional classifications, except for the normotype.
  • The breviligne morphotype liver is primarily in the right hypochondrium; the longiligne liver extends into the left hypochondrium.

Conclusions:

  • Ultrasonography is effective for classifying human morphotypes and liver anatomy.
  • This method provides a more dynamic and precise understanding of liver topography.
  • Findings challenge traditional anatomical descriptions for breviligne and longiligne morphotypes.
