Overview
Whole-body diffusion-weighted imaging (DWI) enables comprehensive
evaluation of systemic diseases such as lymphoma and metastatic cancers
by capturing high b-value images (e.g., up to 1000 s/mm²) across
multiple stations, typically from the skull base to mid-thigh.
DWI of the abdomen and pelvis plays a crucial role in detecting and
characterizing pathologies such as hepatic metastases, prostate cancer,
and pelvic malignancies, using axial DWI with multiple b-values and
generating ADC maps to assess tissue cellularity and differentiate
benign from malignant lesions. A key focus will also be on recognizing
and managing common artifacts and technical challenges encountered in
body DWI, including motion, susceptibility, and distortion effects. In
the evaluation of multiple sclerosis (MS), diffusion imaging,
particularly with diffusion tensor imaging (DTI), is valuable for
characterizing microstructural integrity, offering insights through
parameters like fractional anisotropy (FA) and mean diffusivity (MD),
which help in monitoring disease progression and demyelination beyond
conventional imaging capabilities.
Target Audience
MRI radiographers and technologists.
Educational Objectives
As a result of attending this course, participants should be able to:
• Understand the physics and optimisation of MRI diffusion methods to
perform whole-body diffusion;
• Recognise common artifacts and existing solutions in diffusion MRI of
the abdomen and pelvis; and
• Understand how diffusion imaging is used to characterise
microstructural changes in MS.
