Case (3): A 69 year old male patient with history of rectal adeno-carcinoma with solitary hepatic metastasis a) Baseline T2 axial MRI revealed a small solitary hepatic dome hyper intense lesion at segment IV A b) corresponding axial baseline diffusion weighted image of the previous T2 target lesion with b value of (800 m2/sec) shows the lesion displaying hyper intense signal. c) pre therapeutic ADC image revealed diffusion restriction and ADC value of 0.71 x10-3 m2/sec. (d) post therapeutic (21 days after chemotherapy) ADC map showing marked increase in the ADC value measuring 1.38 x10-3 m2/sec (e) base line pre chemotherapy CT portal phase; shows the same small hypo dense target lesion measuring about 1.4 cm. (f) 2 month follow up CT portal phase revealed significant increase in the size of the lesion which was seen measuring about 3.2 cm (progressive disease according to RECIST criteria)
