Liver volume determination by ultrasound: a feasibility study

Area of Science:

• Medical Imaging
• Hepatology
• Diagnostic Ultrasound

Background:

• Accurate liver volume measurement is crucial for clinical assessment and surgical planning.
• Traditional methods for liver volume estimation can be invasive or imprecise.

Purpose of the Study:

• To evaluate the feasibility and precision of an ultrasound-based method for determining liver volume.
• To establish a relationship between estimated liver volume and body weight.

Main Methods:

• Utilized a Nuclear Enterprises B-scan machine for ultrasound imaging.
• Assessed the precision of liver volume estimation.
• Investigated the correlation between estimated liver volume and patient body weight.

Main Results:

• Established a relationship between estimated liver volume and body weight.
• Achieved a precision of +/- 195 cm3 for liver volume determination (P <= 0.05).
• Identified uncertainty in liver boundary definition as the primary source of error.

Conclusions:

• Ultrasound offers a feasible method for estimating liver volume with quantifiable precision.
• Liver volume estimation via ultrasound is influenced by body weight.
• Improving liver boundary definition in non-grey-scale ultrasound could enhance accuracy.
