New Scan Spots Hidden High Blood Pressure Cause
27 Nov
Summary
- A new 10-minute scan can diagnose a common, hard-to-treat cause of high blood pressure.
- The PET-CT scan visualizes overactive adrenal glands producing excess aldosterone.
- This British innovation could transform diagnosis and lead to targeted treatments.

Researchers at University College London have unveiled a new 10-minute PET-CT scan capable of diagnosing a previously hidden cause of high blood pressure. This innovative test can pinpoint overactivity in adrenal glands that produce too much aldosterone, a hormone regulating salt levels, which affects roughly a quarter of individuals with hypertension.
The PET-CT scan utilizes a novel radioactive tracer designed to bind to aldosterone synthase, illuminating over-producing areas of the adrenal glands. This capability was previously invisible to other diagnostic methods. Experts anticipate this British innovation will profoundly change diagnostic approaches, enabling more precise treatment strategies, including medication or surgical options.
This breakthrough builds on a decade of research into new radioactive tracers. Following successful trials on 17 patients, a phase 2 clinical trial is now underway to seek NHS approval. This advancement holds significant potential for the 14 million people in the UK living with high blood pressure, a condition that elevates the risk of serious health issues.
