Lesion in segment VII with a change in categorization from category 2 on ¹⁸F-DOPA-PET/CT to category 1 through additional features on gadoxetic acid-enhanced MRI. a Contrast enhanced CT. b ¹⁸F-DOPA-PET/CT (fusion image). c, d, e, f T1 GRE fs with arterial, portal venous, late dynamic, and hepatobiliary phase. g T2. H: DWI, b800. ¹⁸F-DOPA-PET/CT a and b shows a small hypodense lesion (arrow) without ¹⁸F-DOPA uptake read as category 2 (probably benign). As MRI showed no contrast enhancement (c-e), no diffusion restriction but T2 shine through in the ADC map (h), and it appeared homogenously hyperintense on T2 (g), it was categorised as a benign cyst (category 1 – definitely benign)
