MRI Brain with Perfusion (ASL) – Contrast is an advanced MRI examination that combines structural brain imaging, non-invasive arterial spin labelling perfusion, and contrast-enhanced imaging to assess cerebral blood flow and characterize tumors, ischemic changes, vascular abnormalities, and other neurological conditions, supporting accurate diagnosis and clinical management.

Yes. ASL can provide information about blood flow within and around a brain lesion, while contrast-enhanced MRI can help assess its enhancement pattern, location, and extent. Together, these findings can support lesion characterization and treatment planning.
Yes. A routine brain MRI primarily evaluates brain structure, while this examination adds cerebral blood-flow assessment using ASL and contrast-enhanced imaging for additional tissue and lesion characterization.
Preparation depends on the centre's protocol. If contrast is planned, inform the MRI team about kidney disease, previous contrast reactions, pregnancy or possible pregnancy, metallic implants, pacemakers, and other implanted medical devices. Follow any fasting instructions provided.
Depending on the findings, your doctor may recommend diffusion MRI, MR angiography, CT, CT angiography, PET-CT, blood tests, biopsy, or consultation with a neurologist, neurosurgeon, or oncologist.
This examination may be recommended for patients with brain tumors, suspected or recent stroke, cerebral ischemia, vascular abnormalities, unexplained neurological symptoms, or other conditions where assessment of brain blood flow is clinically important.
