Stereological measurement of liver volume in newborn cadavers
Abstract
Purpose: The aim of our study was to compare different techniques for the estimation of liver volume using cadaveric sample, magnetic resonance imaging (MRI) and ultrasonography (USG) images, and to measure errors associated with volume estimation techniques based on fluid displacement (the Archimedes' principle).
Materials and Methods: Our study was formed of five newborn cadavers aged 39.7±1.5 weeks and weighted 2.220±1.056 g. We used three different methods for calculate the liver volume.
Results: Liver volume (LV) measured by the Archimedes' principle was 70.00±49.96 cm3. There was no significant difference between the methods.
Conclusion: MR and USG images provide easy, applicable and reproducible estimates in calculating volume of normal and anomalous liver with the Cavalieri’s principle. We think that our study may be a reference for similar studies to be done in the upcoming years.
