Information for Consumers - Hypertension

This article tells you about hypertension and how it is diagnosed, including what imaging tests you may need to have.


What is hypertension?

Hypertension is high blood pressure. High blood pressure usually does not cause any symptoms. However, some symptoms of hypertension are:

  • Headache
  • Palpitations
  • Tiredness
  • Vision changes

What causes hypertension?

There is usually no specific cause, however, in some people hypertension is due to:

  • Underlying kidney disease or disease of the arteries to the kidneys (renovascular hypertension)
  • Disease of the adrenal glands


Your doctor will discuss the signs and symptoms of your hypertension. If he/she thinks that your hypertension is due to an underlying problem in the kidneys and adrenal glands then you may need an imaging test called a doppler ultrasound.


Depending on your doppler ultrasound your doctor may request a CT scan, MRI scan or nuclear medicine renal scan.



A radiology doctor will look at your scans and write a report for your doctor.
