'Kill-painting' tackles hypoxic tumours

Treatment plans based on "kill-painting" optimize ion beam therapy for hypoxic tumours.

Sensitive imager boosts cancer cell detection

A sensitive imaging system that detects a fluorescent biomarker in tumour cells could enable more accurate brain tumour excision.

Proton therapy is 'as effective and less toxic'

Treating paediatric medulloblastoma with proton therapy is as effective as conventional radiotherapy, while causing fewer long-term toxic effects.

Gadolinium not essential in paediatric MRI

Gadolinium-based contrast agents are not necessary in PET/MRI scans to evaluate tumours in paediatric patients.
