詳細な説明
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a non-invasive quantitative technique for assessing micro-vascular structure by tracking the pharmacokinetics of injected low-molecular weight contrast agents as they pass through the tumor vasculature. This modality is being increasingly used in many oncological studies to characterize tumor angiogenesis and invasiveness, and monitor the treatment response.
Diffusion-weighted imaging (DWI) enables qualitative and quantitative assessment of tissue diffusivity (apparent diffusion coefficient, ADC) without the use of gadolinium chelates. DWI has been suggested to be useful in monitoring the response of HCC after TACE because of earlier assessment of tumor necrosis with increasing ADC values.
MR spectroscopy facilitates the study of cellular metabolism and in vivo detection of abnormalities. A few studies of in vivo MR spectroscopy reported an increase in choline levels within tumors such as HCC and a reduction in the lipid-to-choline ratio after conventional TACE was performed for HCC.
