Formula for calculating percentage change:

Percentage Change in Volume = ((New Volumenew – Old Volumeold) / Old Volumeold) x 100

Interpret results of interval change in volume with caution, especially for lesions measuring less than a centimeter as these are most often due to differences in measurement techniques.
