Oncologic applications of diffusion-weighted MRI in the body.
Diffusion-weighted MRI (DWI) allows the detection of malignancies in the abdomen and pelvis. Lesion detection and characterization using DWI largely depends on the increased cellularity of solid or cystic lesions compared with the surrounding tissue. This increased cellularity leads results in restricted diffusion as indicated by reduction in the apparent diffusion coefficient (ADC). Low pretre...
متن کاملDiffusion-weighted MRI for body imaging applications
Diffusion is the thermally induced motion of water molecules in biological tissues, called Brownian motion. Diffusion-weighted MRI (DWI) by means of apparent diffusion coefficient (ADC) calculation can be used for in vivo quantification of the combined effects of capillary perfusion and diffusion. With the advent of echoplanar imaging (EPI), DWI of the abdomen has become possible with fast imag...

متن کاملDiffusion-weighted MRI in the body: applications and challenges in oncology.
OBJECTIVE In this article, we present the basic principles of diffusion-weighted imaging (DWI) that can aid radiologists in the qualitative and quantitative interpretation of DW images. However, a detailed discussion of the physics of DWI is beyond the scope of this article. A short discussion ensues on the technical aspects of performing DWI in the body. The emerging applications of DWI for tu...
متن کاملDiffusion - weighted imaging for body imaging applications
Diffusion-weighted MRI (DWI) by means of apparent diffusion coefficient (ADC) calculation can be used for in vivo quantification of the combined effects of capillary perfusion and diffusion. With the advent of echoplanar imaging (EPI), DWI of the abdomen has become possible with fast imaging times minimizing the effect of gross physiologic motion from respiration and cardiac movement. Several s...
