MRI Kub

What an MRI KUB scan shows

• Size, shape, and position of both kidneys
• Full length of the ureters (the tubes draining urine)
• Bladder wall thickness and volume
• Stones, tumors, cysts, infections, or birth anomalies

How it compares to CT KUB & ultrasound

• Detect kidney stones without radiation exposure
• Evaluate urinary tract obstruction before surgery
• Stage bladder or renal tumors pre-treatment
• Follow up congenital anomalies (duplex kidney, PUJ obstruction)

• High-resolution soft-tissue detail
• No ionising radiation—safe for children and follow-ups
• Multi-planar imaging—front, side, and angled views in one session

• Renal calculi/nephrolithiasis
• Ureteric strictures or stones
• Bladder carcinoma
• Congenital anomalies: duplex collecting system, posterior urethral valves, PUJ obstruction

• Fasting: 4 hours before the scan if contrast is planned.
• Metal removal: Leave jewelry, hairpins, hearing aids, and credit cards at home or in the locker.
• Pregnancy or implants: Inform the technologist—extra safety steps will follow.

• Recent creatinine test (within 30 days) if gadolinium contrast is expected.
• Signed consent form covering the procedure and contrast risks.

• Morning slots reduce waiting time and allow same-day report turnaround.
• Avoid active menstrual days if contrast is required (may cause scheduling delays).

• Adults and children above 5 years (co-operation dependent).
• Pregnancy: Non-contrast only after the 1st trimester.

1. Arrival: 30 minutes early for paperwork and safety screening.
2. Changing room: Remove all metal objects; change into hospital gown if needed.
3. Positioning: Lie on the scanner table; a small coil is placed over your abdomen.
4. Breath-hold sequences: You’ll be asked to hold your breath for 10–15 seconds at a time.
5. Total scan time: 20–30 minutes (add 10 minutes for contrast injection).

• Remove jewelry, watches, and hearing aids.
• Inform staff of tattoos, pacemaker, or prior contrast reactions.
• Sedation is available for claustrophobic patients—discuss during booking.

• Claustrophobia: Open-bore or wide-bore machines, plus light sedation, reduce anxiety.
• Contra-indications:
• Cardiac pacemaker or defibrillator
• Cochlear implants or certain metallic fragments
• Severe allergy to gadolinium contrast (rare) Cadabams Diagnostics runs a detailed safety checklist before every scan.
