- Primary Outcome Measures
Name Time Method 1) Lung structure <br><br>We will use a version of the PRAGMA-CF scoring system (widely used in CF CT scan studies), adapted for use in MRI, for assessment of structural lung abnormalities.15 In brief, PRAGMA-CF involves overlaying a square grid over the MRI images and annotating grid cells for the presence of CF-related structural lung disease. The total proportion of the lung with disease, %Disease, is reported and represents the extent of structural disease. Additionally, the extent of mucus plugging, %MucusPlugging, will be reported. <br>[On day of MRI];2) Lung ventilation<br><br>The same PRAGMA-CF process will be used to determine the severity of hypoventilation in the lung, from the Fourier Decomposition scans (%Hypoventilated).[On day of MRI]
