A 66-years-old male patient with cirrhosis having RF ablation for right lobe focal lesion, dynamic MRI was done with subtraction technique 1 month after RF ablation, a coronal T1WI showing bright signal of the ablated Lesion (yellow arrow) with hypointense signal of the track (red arrow), b coronal T1WI showing bright signal of the ablated Lesion, c axial dynamic T1WI Early Arterial post contrast showing bright signal of the Lesion possibly due to preexisting bright signal or due to tumoral enhancement, d axial dynamic late arterial phase the ablated site appeared inconspicuous becoming isointense to the rest of the liver parenchyma, e subtraction MRI confirmed non enhancement with well ablation of the lesion removing the native T1 signal as well as background suppression of the lesion in relation to the enhanced liver parenchyma increasing the degree of confidence
