The Potential of Fluid-attenuated Inversion Recovery Imaging in Improving Glioblastoma Outcome?

The outcome of Glioblastoma (GBM) remains poor. Standard management includes surgical resection, which is guided by magnetic resonance imaging (MRI). Surgery alone however is not able to reliably remove all tumour cells, which due to their diffuse and infiltrative nature, migrate along pathways outside the confines indicated by MRI. The use of fluid-attenuated inversion recovery (FLAIR) imaging has emerged as a potential adjunct to current surgical treatment, and its rationale in order to better GBM outcomes is discussed.
