Summary
Artificial Intelligence (AI) accurately measured tumor long-diameters, improving efficiency and reducing errors in treatment response evaluation. AI measurements showed good agreement with manual methods, unlike 3D measurements.
Area of Science:
- Oncology
- Medical Imaging
- Artificial Intelligence
Background:
- Accurate tumor size measurement is crucial for evaluating treatment response in oncology.
- Manual measurement of tumor dimensions can be subjective and time-consuming.
- AI offers potential for automated and objective image analysis.
Purpose of the Study:
- To assess the feasibility and accuracy of using Artificial Intelligence (AI) for measuring tumor long-diameter.
- To compare AI-based measurements with manual radiological measurements for treatment response evaluation.
Main Methods:
- 48 patients with lung tumors underwent 277 measurements.
- Radiologists manually measured tumor long-diameter in the axial plane.
- AI software measured long-diameter in both axial and 3D planes.
- Statistical analyses included Bland-Altman plots, Spearman correlation, and paired t-tests.
Main Results:
- AI measurements showed good agreement with manual measurements (bias -0.28 mm, P=0.497).
- Three-dimensional (3D) AI measurements did not agree with manual measurements (P<0.001).
- AI measurements demonstrated no statistically significant difference from manual measurements (P=0.497).
Conclusions:
- AI measurement of tumor long-diameter is feasible and reliable for treatment response evaluation.
- AI enhances efficiency and reduces subjective errors in tumor measurement.
- AI-based tumor measurement offers a more convenient and accurate approach.
