This is the standard clinical approximation used in radiology for roughly ellipsoid tumors. For irregular or complex shapes, segmentation-based volumetry from the DICOM dataset is more accurate.
(π / 6) × L × W × H ≈ 0.5236 × L × W × HThis is the standard clinical approximation used in radiology for roughly ellipsoid tumors. For irregular or complex shapes, segmentation-based volumetry from the DICOM dataset is more accurate.
