Comparison of Echo Planar and Turbo Spin Echo Diffusion-Weighted Imaging in Intraoperative MRI.

Article Synopsis
- Diffusion-weighted imaging (DWI) is a method used in brain tumor surgeries with intraoperative MRI, but traditional techniques like echo planar imaging (EPI-DWI) can suffer from image distortions and artifacts.
- This study compares EPI-DWI and a less distorted technique known as turbo spin echo DWI (TSE-DWI) to see which one radiologists prefer during surgery.
- Results indicate that TSE-DWI performs equally or better than EPI-DWI in terms of image quality, particularly in reducing distortions and artifacts, making it a better option for intraoperative imaging.
Background: Tumour hypoxia is a recognised cause of radiotherapy treatment resistance in head and neck squamous cell carcinoma (HNSCC). Current positron emission tomography-based hypoxia imaging techniques are not routinely available in many centres. We investigated if an alternative technique called oxygen-enhanced magnetic resonance imaging (OE-MRI) could be performed in HNSCC.

Hypothesis: The trajectory of changes in relative dentate nucleus (DN) and globus pallidus (GP) SI in children receiving multiple doses of GBCA will alter when switched from linear to macrocyclic agents.
Study Type: Retrospective longitudinal.
