Official title
Advanced MRI for Visualization and Quantification of the Tumor Immune Microenvironment (TIME) in Glioblastoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase III trial is evaluating whether a combination of three advanced magnetic resonance imaging (MRI) techniques, including chemical exchange saturation transfer (CEST) MRI, diffusion-relaxation correlation spectrum imaging (DR-CSI), and ferumoxytol-enhanced magnetic resonance imaging (Fe-MRI) are effective as non-invasive methods for assessing the cells and proteins that surround and interact with tumor cells (the tumor immune microenvironment) in patients with glioblastoma. Researchers understand that some types of brain tumors are harder to treat than others, but the reasons for this are not known in many cases. CEST MRI uses differences in the tissue microenvironment, like protein concentration or intracellular pH, to generate contrast differences. DR-CSI detects microstructural changes in tissue associated with immune cells infiltrating the tumor. Fe-MRI uses ferumoxytol as a contrast agent with MRI. Contrast agents are substances that are injected into the body and taken up by certain tissues, making the tissues easier to see in imaging scans. More advanced imaging techniques like CEST, DR-CSI, and Fe-MRI may offer less invasive methods than surgery or biopsy for helping researchers understand the tumor immune microenvironment in patients with glioblastoma, which may help researchers determine why some tumors are more resistant to treatment.
