This observational study, called VEGA, is looking at how useful a special type of Magnetic Resonance Imaging (MRI) is for finding inflammation in the arteries that supply blood to your head, brain, and eyes. This is for people suspected of having Giant Cell Arteritis (GCA), also known as temporal arteritis. The study aims to see if this MRI can help diagnose GCA by measuring something called the Vessel Wall Enhancement Score over a period of up to 12 months. You might be able to join if you are 50 or older, have new or worsening head symptoms, have an elevated CRP (a blood test for inflammation) greater than 1.0 mg/dl, and are planning to have a temporal artery biopsy or ultrasound for diagnosis. The study plans to enroll 400 participants, but its current recruitment status is unclear.

Study design

This is an observational study with a planned enrollment of 400 participants. It is not a treatment study but rather looks at how a diagnostic test performs.

What's involved

You would have an MRI scan within two weeks of joining and fill out questionnaires. You might also have follow-up visits and MRI scans at 6 months or if your symptoms return.

Compensation

Not stated in the trial record.

Follow-up

You may have follow-up visits and MRI scans at 6 months after the initial scan or at the time of relapse, with the primary endpoint measured up to 12 months.
