In other words, by stacking 2D images, you get the volume (case or patient). They're all taken at the same time. I hope this helps.</p>",

So, positive week value in the CSV file indicates that this FVC has been recorded after the CT scan. Negative values mean that this FVC has been recorded before the scan. For example: a week value of -2 means that the corresponding FVC value has been recorded two weeks before the CT scan. Hope that helps.</p>",
