From: Does liver diffusion tensor imaging (L-DTI) has a role in differentiation of hepatic focal lesions? Analytic study for assessment of the value of L-DTI in differentiating hepatic focal lesions according to LI-RADS

A 27-year-old female patient with past history of viral C hepatitis underwent routine abdominal ultrasonography that showed left hepatic focal lesion. A Axial T2 image shows A 3.7 cm left lobar segment III focal lesion eliciting high T2 signal with central hypo-intense scar. B axial diffusion and C ADC images show no diffusion restriction with DWI-ADC value 1.51 D Axial DTI gray scale image, E DTI-ADC map and F FA map: the DTI-ADC value was 1.57 and the FA value was low = 0.26 suggestive of benign nature. G non-contrast T1 H arterial phase and I delayed phase of the dynamic study showed homogenous arterial enhancement with enhancement of the central scar in the delayed phase. The lesion was categorized as LR-3. Imaging features were suggestive of FNH which is proved by histopathology
