These changes inhibit the movement of water molecules, with resultant restriction of diffusion and reduction of ADC values in the cancer tissue. The abnormality can represent benign cysts all the way to advanced cancer. Although focal liver lesions are commonly detected because of their iso- or hypointensity on T1-weighted images, lesions (benign or malignant) may present with T1 hyperintensity when they contain T1 shortening elements--such as fat, hemorrhage, copper, melanin, and highly concentrated proteins.
