Abstract EN
Diametric analysis is the standard approach utilized for tumor measurement on medical imaging.
However, the availability of newer more sophisticated techniques may prove advantageous.
An evaluation of diameter, area, and volume was performed on 64 different lung lesions by three trained users.
These calculations were obtained using a free DICOM viewer and standardized measuring procedures.
Measurement variability was then studied using relative standard deviation (RSD) and intraclass correlation.
Volumetric measurements were shown to be more precise than diametric.
With minimal RSD and variance between different users, volumetric analysis was demonstrated as a reliable measurement technique.
Additionally, the diameters were used to calculate an estimated area and volume; thereafter the estimated area and volume were compared against the actual measured values.
The results in this study showed independence of the estimated and actual values.
Estimated area deviated an average of 43.5% from the actual measured, and volume deviated 88.03%.
The range of this variance was widely scattered and without trend.
These results suggest that diametric measurements cannot be reliably correlated to actual tumor size.
Access to appropriate software capable of producing volume measurements has improved drastically and shows great potential in the clinical assessment of tumors.
Its applicability merits further consideration.
