AI Could End Brain Tumor Dye Injections
16 Sep
Summary
- AI may eliminate contrast dye for brain tumor MRIs.
- Technology predicts tumor enhancement without gadolinium.
- Study showed 83% accuracy in predicting tumor brightness.
Brain tumour patients could soon undergo MRI scans without contrast dye injections, thanks to a new artificial intelligence tool. Developed by experts at UCL, the AI can predict which tumours will enhance during a scan, potentially eliminating the need for gadolinium. This technology was tested using over 11,000 MRI scans from patients across the UK, US, the Netherlands, and Nigeria.
The AI tool achieved an 83% accuracy rate in predicting tumour brightness on non-contrast images. It correctly identified 92% of tumours that did brighten and 74% that did not. While most accurate for meningioma, its performance was less reliable in children, indicating it's not yet a complete replacement for current methods.
Researchers suggest this AI could serve as a decision-support aid, flagging studies where contrast enhancement is likely. This could prevent patients from needing a second hospital visit and minimize delays in care. However, they emphasize further optimization with radiologists is needed before it can fully replace contrast-enhanced MRI, especially for pediatric patients.
