Fig. 3: Trajectory of a simple cyst growing, shrinking, and eventually transitioning into a complex cyst.

A Simple cyst (pink) of a female ADPKD subject, 56-year-old at index scan in 2006. B The cyst eventually transitioned into homogeneously T1-bright complex cyst (cyan) in 2024. C All available scans show the cyst was first growing at rcyst = 5% per year (R2 = 0.83), transitioned in 2012 to shrinking (rcyst = −10% per year, R2 = 0.90), eventually further transitioning to homogeneously T1-bright complex cyst.
