Note: this calculator can provide an estimate of lung nodule volume for e.g. VDT calculations, assuming a spherical shape. For solid nodules it has a larger margin of error than proper volumetry, however it can be useful for e.g. subsolid nodules where automated volumetry is more difficult.
Notes
- This calculator uses the following formula: V = 1/6 x π x D3
- Where:
- V = nodule volume
- D = manually measured maximum diameter
- This formula has been used previously for manual nodule measurements and volume estimation during the NELSON trial.
