MRI Scans and Headaches: When It's Time to Look Further
MRI is a safe, radiation-free way to investigate headaches and rule out serious causes like space-occupying lesions (tumours, cysts, abnormal growths). The article explains what MRI can identify (tumours, bleeds, raised pressure, structural or inflammatory causes), lists key red flag symptoms that warrant investigation (thunderclap onset, new headache over 50, posture-related, neurological symptoms, fever/neck stiffness, progressive worsening, exertion-triggered, seizures), and highlights the ease of the scan (no injection needed, 20–30 min, consultant-reported).
