Diffusion weighted imaging: Technique and applications
Diffusion weighted imaging (DWI) is a method of signal contrast generation based on the differences in Brownian motion. DWI is a method to evaluate the molecular function and micro-architecture of the human body. DWI signal contrast can be quantified by apparent diffusion coefficient maps and it acts as a tool for treatment response evaluation and assessment of disease progression. Ability to d...
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...
متن کاملApplications of diffusion weighted imaging in detection of radiating pain to lower extremities
Introduction: To examine the hypothesis that diffusion weighted imaging (DWI) in lumbosacral region could reveal sciatic nerve course swelling that lead to lower extremity pain. The aim of present article was to find and evaluate the diffusion weighted coefficients (b-values) for scrutinizing sciatic nerve tract changes in lumbosacral region. Materials and methods: Lumbar area was imaged in 30...

متن کاملComparison Between Three-Dimensional Diffusion-Weighted PSIF Technique and Routine Imaging Sequences in Evaluation of Peripheral Nerves in Healthy People
Introduction: The present study aims to evaluate the Three-Dimensional Diffusion-Weighted reversed fast imaging with steady state free precession (3D DW-PSIF) sequence with respect to imaging of the peripheral nerves; the tibial, medial, and lateral plantar nerves in the lower extremity, ulnar and median nerve in the upper extremity, sciatic nerve, brachial plexus, and lumbosacral plexus, and a...
