Summary
Area measurement of pulmonary tumors using multidetector computed tomography (MDCT) is the most reproducible method. This technique provides accurate tumor dimension assessment, outperforming other measurement approaches.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Pulmonary tumors require accurate dimension measurement for effective management.
- Multidetector computed tomography (MDCT) is a key imaging modality for thoracic evaluation.
- Various methods exist for measuring tumor dimensions on MDCT, with varying reliability.
Purpose of the Study:
- To compare the agreement of unidimensional, bidimensional, area, and volume measurements of pulmonary tumors on MDCT.
- To identify the most reliable method for assessing pulmonary tumor dimensions using MDCT.
Main Methods:
- Thirty patients with pulmonary tumors underwent thoracic MDCT.
- Four radiologists independently measured tumor dimensions (length, width, height, area, volume).
- Intraclass correlation coefficient (ICC) and concordance correlation coefficient (CCC) were used to assess intra- and interobserver variability.
Main Results:
- Both intraobserver and interobserver agreements were higher for area measurements compared to other methods.
- Area measurement demonstrated the highest ICC and CCC values in both intraobserver and interobserver analyses.
- Intraobserver agreement (ICC=0.992, CCC=0.997) and interobserver agreement (ICC=0.981, CCC=0.982) for area were excellent.
Conclusions:
- Area measurement on MDCT is the most reproducible method for assessing pulmonary tumor dimensions.
- This method offers accurate tumor dimension assessment, enhancing diagnostic reliability in oncology.
