Body imaging
Thyroid Volume
Total thyroid volume from the two lobes by the Brunn / WHO method (length × width × depth × 0.479 per lobe). The isthmus is conventionally excluded.

Enter all values to calculate.
Formula
Lobe volume = L × W × D × 0.479 (Brunn / WHO). Total = right + left lobe. (π/6 ≈ 0.524 is the uncorrected ellipsoid and reads 9% higher.)

Disclaimer
The formula loses accuracy in enlarged, nodular or asymmetric glands (Brunn: mean error 16%); thresholds assume iodine-replete adults. Correlate with clinical assessment.
