A new scan could improve how millions of people with high blood pressure are treated, suggests a new study led by UCL and conducted at UCLH.
About a quarter of people with high blood pressure have been estimated to have a problem with their adrenal glands producing too much of the hormone aldosterone, which regulates levels of salt in the body. This problem is often missed, as the path to diagnosis is complex, involving multiple tests and, to guide treatment, an invasive procedure that is not always reliable.
The new 10-minute scan, developed at UCL, reveals overactivity in adrenal glands that was invisible with conventional tests, showing exactly where too much aldosterone is being made. This, the researchers say, will make it easier to decide on the best treatment approach.
