Purpose
Initial assessing the role of Whole-Body Diffusion-Weighted Magnetic Resonance Imaging (WBDW- MRI) in comparison with PET/CT for detection of metastases.
Diffusion MRI is a specific Magnetic Resonance Imaging (MRI) modality that produces in vivo images of biological tissues weighted with the local microstructural characteristics of water diffusion.
Whole-Body Diffusion-Weighted Magnetic Resonance Imaging (WBDW- MRI) has the potential to help detect primary tumors and metastasis.
Differentiating benign from malignant lesions,
and determining the presence of disease recurrence.
DW- MR imaging enables qualitative and quantitative assessment of tissue diffusivity (apparent diffusion coefficient) without the use of gadolinium chelates.
Its high contrast resolution,
lack of ionizing radiation,
and the possibility of performing functional imaging sequences.
With advances in hardware and coil systems.
It a highly attractive technique,
has potential alternative to PET/CT for detection of metastases.
