Intravoxel incoherent motion model–based analysis of diffusion-weighted magnetic resonance imaging with 3 <em>b</em>-values for response assessment in locoregional therapy of hepatocellular carcinoma Open
In patients with HCCs undergoing embolization therapy, diffusion changes were better reflected by D' than by conventional ADC(0,800), which is influenced by counteracting perfusion changes as assessed by f'.

Colonoscopy detects significantly more flat adenomas than 3-tesla magnetic resonance colonography: a pilot trial Open
MRC does not detect adenomas sufficiently independently of the location of the lesion. Even advanced lesions were missed. Therefore, colonoscopy should still be considered the current gold standard, even for diagnostic purposes.
