When Might You Need a Brain MRI Scan? Understanding the Process


Professional brain MRI diagnostic imaging at Marris Medical in London

A brain MRI scan may be recommended when a healthcare professional needs detailed images of the brain and surrounding structures. MRI uses powerful magnetic fields and radio waves to produce detailed images and does not use ionising radiation.

A brain MRI may be considered to investigate symptoms such as:

  • Persistent or unusual headaches
  • Unexplained dizziness
  • Seizures
  • Changes in vision
  • Balance or coordination problems
  • Memory concerns
  • Other neurological symptoms

The need for a scan depends on your individual symptoms, medical history, and clinical assessment.

What Happens During a Brain MRI?

Before your scan, you will complete an MRI safety questionnaire. You should inform the imaging team about:

  • Medical implants or devices
  • Previous surgery
  • Metal fragments or objects in your body
  • Any concerns about enclosed spaces

During the examination, you will lie on a scanning table while detailed images are taken. The MRI machine may make loud tapping or knocking sounds, and remaining still helps produce clear images.

At Marris Medical, we provide professional diagnostic imaging in London with a focus on patient comfort and high-quality care. Our experienced radiologists and radiographers use appropriate scanning protocols to support your examination.
