MRI scans

MRI kidneys and adrenals

A scan that characterises kidney masses and cysts and helps distinguish benign adrenal nodules from ones needing further work-up.

What to expect

  • Preparation: Usually none - eat, drink and take medication as normal unless told otherwise. You will complete a safety questionnaire covering implants and previous surgery, and remove all metal items before the scan.
  • During the test: You lie on a motorised couch that moves into the scanner. The machine is noisy, you wear ear protection, and you need to keep as still as possible. Most MRI examinations take 20-45 minutes.
  • Results: A consultant radiologist reports the scan, typically within 24-72 hours of your appointment.
  • Who follows up: The report goes to your referring GP or specialist, who explains the findings and arranges any follow-up.
  • Cost: an indicative cost varies by provider.

About this test

A scan that characterises kidney masses and cysts and helps distinguish benign adrenal nodules from ones needing further work-up. It is usually recommended when symptoms persist, when an examination or earlier test raises a question that needs detailed imaging, or when a specialist wants a definitive answer before planning treatment.

How to access it privately

You can arrange a private MRI either with a referral from your GP or specialist or, for many scans, by self-referring as a self-pay patient with a short pre-scan questionnaire. Routine NHS diagnostic waits are often long - frequently measured in months - whereas private slots are typically available within days to around two weeks. Costs vary by provider and should be confirmed with the provider before booking.

Frequently asked

Common questions about MRI kidneys and adrenals.

Quick, plain-English answers to what people ask us most.

  • What is an MRI of the kidneys and adrenals and what does it show?

    This scan provides detailed images of the kidneys and the adrenal glands, small hormone-producing glands that sit above each kidney. It can show structural problems in the kidneys as well as growths or abnormalities in the adrenal glands.

  • Why would a doctor order this scan?

    It's often used to further assess a kidney or adrenal abnormality first spotted on ultrasound or CT, to investigate certain hormone imbalances that point to an adrenal problem, or to check kidney structure in some cases of kidney disease. It's also used to monitor known findings over time.

  • Do I need to prepare for the scan?

    You may be asked to fast for a few hours beforehand, and contrast dye is often used, so mention any allergies or kidney function concerns when booking, as this can affect whether contrast is suitable. Let the team know about any implants as usual.

  • What happens during the scan?

    You lie on the scanner table while the abdomen is imaged, sometimes with instructions to hold your breath briefly at points to keep the images sharp. The scan typically takes 30 to 45 minutes.

  • Does it hurt, and are there any risks?

    The scan is painless and doesn't involve radiation. If contrast is used, it's generally well tolerated, though it may be avoided or used cautiously if kidney function is significantly reduced.

  • How long do results take?

    A radiologist reviews the images, with private results usually available within a few days. Your doctor or endocrinologist will then explain the findings alongside your other test results.

  • What do abnormal results mean?

    Findings might include a benign cyst, a kidney structural abnormality, or an adrenal growth, many of which are common and not cancerous. Your doctor will interpret the finding together with your symptoms and blood or hormone tests to decide if further action is needed.

  • How much does a private kidney and adrenal MRI cost, and is it available on the NHS?

    This scan is available on the NHS, with waiting times depending on urgency and local capacity. Private scans are usually available within days with prompt reporting; cost varies by provider.

  • Is this scan accurate and reliable?

    MRI gives detailed soft-tissue information about the kidneys and adrenal glands and is particularly useful for characterising adrenal masses. It's often used alongside blood tests, especially hormone levels, for the fullest assessment.

  • How do I book a private kidney and adrenal MRI, and how quickly can I be seen?

    Private imaging providers can typically arrange this scan within a week. Contact a provider directly to check appointment availability and any preparation needed.
