Lung Nodule Growth Rate Calculator
Calculate pulmonary nodule volume doubling time (VDT) between CT scans
Thoracic Radiology Guidelines: Lung nodule volume doubling time (VDT) is a critical metric for assessing malignancy risk. Malignant solid pulmonary nodules typically exhibit doubling times between 30 to 400 days. Enter initial and follow-up measurements below.
