Summary
ImageJ software accurately calculates liver volume, correlating strongly with actual resected tissue measurements. This tool aids surgeons in precise preoperative liver volume assessment, crucial for complex liver resections and preventing postoperative complications.
Area of Science:
- Hepatobiliary surgery
- Medical imaging analysis
- Surgical oncology
Background:
- Increasing liver resections necessitate accurate preoperative liver volume assessment.
- Postoperative liver failure risk highlights the importance of precise volume calculations.
- Previous studies validated ImageJ for liver volume estimation against indirect measures.
Purpose of the Study:
- To investigate the correlation between ImageJ-calculated liver volumes and actual resected liver tissue volumes.
- To assess the reliability of ImageJ for preoperative liver volume determination in surgical planning.
- To establish ImageJ as a dependable tool for predicting remnant liver volume.
Main Methods:
- Included 30 patients undergoing defined liver resections.
- Compared ImageJ-calculated liver volumes with direct measurements of resected tissue.
- Utilized concordance correlation coefficient (ρc) for statistical analysis.
Main Results:
- Demonstrated a strong correlation (ρc = 0.9950) between calculated and measured liver volumes.
- Confirmed ImageJ's accuracy in estimating the volume of resected liver tissue.
- Highlighted surgeons' expertise in predicting resection volumes.
Conclusions:
- ImageJ is a highly reliable tool for preoperative liver volume assessment.
- Accurate preoperative volume assessment using ImageJ improves surgical planning and patient outcomes.
- This technology is vital for advancing the scope and safety of liver surgery.
