Diffusion magnetic resonance imaging: A molecular imaging tool caught between hope, hype and the real world of “personalized oncology”

Figure 5 A 45-year-old female with ovarian malignancy, post therapy, presented with sudden onset of abdominal pain and high grade fever. A: Axial T2 W images showed well defined lesions in the right lobe of liver with central hyperintensity and hypointense rim (arrow). However, DWI showed restricted diffusion (B) in the periphery of the lesion with reduced ADC values (C) with central necrotic component which showed facilitated diffusion. The case was diagnosed as necrotic metastases. Final histopathology was hepatic metastasis. ADC: Apparent diffusion coefficient; DWI: Diffusion-weighted imaging.
