MRI urogram
An MRI urogram is a painless, radiation-free scan that gives your care team detailed images of your kidneys, ureters and bladder — used to find the cause of symptoms like blood in the urine, flank pain, or a suspected blockage.

Briefly about this treatment
Indications
Unexplained blood in the urine, ongoing flank or lower-back pain suggesting a blocked or swollen kidney, recurrent urinary tract infections, a suspected structural problem in the urinary tract, or the need for repeat imaging without radiation exposure.
Risks
Rare reactions to gadolinium contrast, discomfort from the enclosed scanner, and limited suitability for certain implants or pregnancy. Risks are minimised through careful pre-scan screening and experienced radiology teams.
Pre-procedure
Screening for MRI-incompatible implants and pregnancy, removal of metal objects and jewelry, a recent kidney-function blood test if contrast is planned, and — depending on the protocol — fasting or extra fluids beforehand.
Follow-up
No fixed follow-up visits are needed for the scan itself. A radiologist sends a report to your referring doctor, usually within a few days, who then discusses results and any next steps with you.
What is MRI urogram? An expert explains
MRI urogram uses a strong magnetic field and radio waves — not radiation — together with a computer to build detailed images of your urinary tract: the kidneys, the ureters (the tubes that carry urine to your bladder), and the bladder itself. There are two main types your radiologist may use, sometimes together: a static-fluid scan, which uses urine already in your urinary tract as a natural contrast and needs no injection, and an excretory scan, where a gadolinium-based contrast dye is injected so the radiologist can watch how your kidneys filter and drain it over time.
Compared with a CT urogram, an MRI urogram doesn’t use ionizing radiation, which is why it’s often preferred for children, pregnant patients, people needing repeat scans, and those with reduced kidney function or an iodine-contrast allergy. The trade-off: it’s less sensitive than CT for picking up small urinary stones.
Signs it may be time for MRI urogram
You might notice:
- Blood in your urine, visible or found on a urine test, without a clear explanation.
- Ongoing pain in your side or lower back that could point to a blocked or swollen kidney.
- Repeated urinary tract infections with no obvious cause.
- A feeling of incomplete bladder emptying or unusual changes in urination alongside other symptoms.
These are the conditions linked to this procedure in the directory. Your clinician decides whether this scan is appropriate using your symptoms, examination and test results.
- Polycystic Kidney Disease (PKD) — Inherited disorder with fluid-filled cysts in the kidneys, often monitored with imaging over time.
- Cystine Stones — A hereditary stone-forming condition where urinary tract imaging helps locate and track stones.
- Tumor Obstructive Nephropathy — Blockage of urine flow caused by a tumor, which MR urography can map in detail.
- Wilms Tumor (Nephroblastoma) — A childhood kidney tumor, where radiation-free imaging is especially valued.
- Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) — An inherited cancer-risk syndrome requiring regular kidney imaging surveillance.

When to consult a specialist
If you’ve noticed blood in your urine, ongoing flank pain, or repeated infections, it’s worth getting checked — these are common and often manageable once the cause is found, so try not to jump to the worst conclusion. A simple blood or urine test is often the first step, and your doctor will tell you if imaging like this is needed. You can consult a specialist directly through our find a specialist tool to get a clear answer sooner rather than later.
How a session works
Check-in and screening. Staff confirm you have no MRI-incompatible implants (pacemakers, certain aneurysm clips, some cochlear implants) and check whether you’re pregnant or could be.
Preparation. You’ll usually remove metal objects, jewelry and anything with a magnetic strip, and change into a gown. Some protocols ask you to avoid solid food for a few hours and drink a specified amount of clear liquid beforehand.
On the table. You lie on a movable exam table, a coil may be placed near the area being studied, and you’ll get earplugs since the scanner is noisy.
Inside the scanner. The table slides into the MRI tunnel. You’ll get breathing instructions at points during the scan to improve image quality.
Contrast (if used). A small IV line delivers gadolinium-based contrast partway through; you may feel a brief cool sensation.
Finishing up. The table slides out, the IV (if placed) is removed, and — unless you were sedated — you can typically get dressed and leave right away.

Benefits
- No radiation exposure, which matters most for children, pregnant patients, and anyone needing repeated scans over time.
- Excellent detail on soft tissue and the structure of the kidneys, ureters and bladder.
- Can assess both anatomy and, with the excretory technique, how well each kidney drains.
- A safe primary option when someone can’t have iodine-based CT contrast because of allergy or reduced kidney function.
Risks & side effects
This scan has risks and trade-offs to discuss with your care team. The information below comes from this procedure’s data. Gadolinium contrast reactions are uncommon and usually mild; certain implants or pacemakers can make the scanner unsafe; and the enclosed tunnel can be uncomfortable for people with claustrophobia. Risks are minimised through careful pre-scan screening and experienced radiology teams.
Who it may not suit: people with certain pacemakers, non-titanium aneurysm clips, or other MRI-incompatible implants; people with significantly reduced kidney function, where contrast needs extra caution; and pregnant patients, where contrast is generally avoided. These are general cautions, not a personal verdict — a qualified clinician must assess your full medical picture before recommending or delaying this scan.
What happens during & after
During the scan, the main thing asked of you is to stay still and follow breathing cues. The machine is loud — expect knocking and buzzing sounds, which is normal. If you feel anxious in enclosed spaces, tell the radiology team beforehand; many centers offer wide-bore scanners, a mirror to see out, music, or a mild sedative.
Afterward, if you didn’t have sedation, you can eat, drink and drive as normal right away. If contrast was used, drinking extra water can help your kidneys clear it, unless your doctor advises otherwise. A radiologist reviews the images and sends a report to the doctor who ordered your scan, usually within days.
Possible complications
- A mild allergic-type reaction to contrast, such as itching or rash — significant reactions are rare with gadolinium-based agents.
- Nephrogenic systemic fibrosis, a rare but serious skin/tissue condition linked to gadolinium contrast in people with significantly reduced kidney function — which is why kidney function is checked beforehand.
- Non-diagnostic or incomplete images if you can’t stay still, or in some cases where the urinary tract isn’t sufficiently filled for a clear static-fluid scan.
Remember:
New or severe symptoms require prompt medical advice. Do not wait for a routine appointment if you feel seriously unwell.
Recovery
There’s no real “recovery” from an MRI urogram — it isn’t invasive, and most people resume normal activities immediately. Watch for any late reaction at the IV site, such as redness or swelling, or signs of an allergic reaction, and contact the clinic if these occur. Your doctor will discuss what the images show and any next steps, which may include further tests, a specialist referral, or starting treatment for an underlying condition.

Good questions
Most Common Questions
Does an MRI urogram use radiation?
No. It uses a magnetic field and radio waves, not X-rays.
Is an MRI urogram the same as a CT urogram?
No — both image the urinary tract, but CT has wider availability and shorter exam times, while MRI gives superior soft-tissue detail and avoids radiation.
Will I need an injection?
Not always. A static-fluid scan needs no contrast; an excretory scan uses an IV gadolinium-based agent, decided based on your kidney function and what your radiologist needs to see.
Is the scan painful?
No. You may feel brief discomfort from lying still, the noise, or a cool sensation if contrast is injected, but the scan itself isn’t painful.
Can I have this scan if I have reduced kidney function?
Often yes for the non-contrast version. Whether you can safely have contrast depends on your current kidney function, which your care team checks first.
How long until I get my results?
A radiologist reviews the images and sends a report to your referring doctor, typically within a few days — ask your clinic about their specific turnaround time.
