What is a MRI BRAIN WITH PERFUSION(ASL)?

MRI Brain with Perfusion (ASL) is an advanced MRI examination that combines structural brain imaging with non-invasive assessment of cerebral blood flow using arterial spin labelling, helping evaluate brain perfusion, tumors, ischemic changes, vascular abnormalities, and other neurological conditions, supporting accurate diagnosis and clinical management.

FAQs

Is MRI Brain with Perfusion (ASL) different from a routine brain MRI?

Yes. A routine brain MRI primarily evaluates brain structure, while ASL adds quantitative information about cerebral blood flow.

Do I need any preparation before the examination?

Usually, no special preparation is required for a non-contrast examination. Inform the MRI team about metallic implants, pacemakers, previous surgeries, pregnancy or possible pregnancy, and other implanted medical devices.

Will I need additional tests after the MRI?

Depending on the findings, your doctor may recommend diffusion MRI, MR angiography, CT or CT angiography, PET-CT, blood tests, or specialist evaluation.

Who may need MRI Brain with Perfusion (ASL)?

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 important.

Can this examination help evaluate brain tumors?

Yes. ASL can provide information about blood flow within a brain lesion, which may help characterize certain tumors and assist with treatment planning.
