Diffusion Tensor Imaging (DTI) of Brachial Plexus

Diffusion Tensor Imaging (DTI) of Brachial Plexus

Diffusion is the random, thermally-induced, microscopic water motion within a tissue, well known as Brownian motion. Diffusion Tensor Imaging (DTI) is an extension of Diffusion-Weighted Imaging (DWI) that takes into account and measures the anisotropic diffusion (nerves are highly anisotropic). DTI can be useful in MR Neurography of the brachial plexus, offering functional information (can …

Fat Suppression in MR Imaging Techniques and Pitfalls

Fat Suppression in MR Imaging: Techniques and Pitfalls

Short TI Inversion Recovery (STIR) sequences can be utilized as a fat suppression technique in MR Imaging. While the other fat suppression techniques are based on the difference between the precession frequency of water and fat, STIR is based on the difference in T1 relaxation time between water and fat in order to achieve fat …

The role of (DCE-MRI) for tumour diagnosis and assessment of PI-RADS

The role of (DCE-MRI) for tumour diagnosis and assessment of PI-RADS

The role of Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) for tumour diagnosis and assessment in the current version of PI-RADS (version 2) is minimized. DCE-MRI is only considered when DWI in the peripheral zone (PZ) is indeterminate. Although, DCE Perfusion has shown potential in prostate cancer detection, localization and staging, assessment of tumour aggressiveness and assessment …
