MRI KUB

MRI KUB is a non-invasive imaging scan used to assess the kidneys, ureters, and bladder. Inguinal MRI does not use any ionizing radiation and achieves clear images soft tissues of the urinary tract which makes it suitable for patients requiring frequent scans or patients who are allergic to contrast dye used in CT scans. 

What is MRI KUB Test? 

MRI KUB is a type of Magnetic Resonance Imaging, that captures fine details the urinary system using magnetic fields and radiofrequency pulses. It is particularly useful when there is a contraindication for a CT scan such as contrast allergies or pregnancy. 

Parameters Considered in MRI KUB

• T1 and T2 weighted images 
• Fat suppression 
• MR Urography: Static or excretory. 
• If contrast is utilised, then pre and post phases. 
• Coronal, sagittal and axial imaging planes. 

Reasons for Performing an MRI KUB

• Tumours arising within the bladder. 
• Chronic pain in the kidney region. 
• Known UTIs as well as suspected repeated UTIs. 
• Known renal masses or cysts. 

When and Who Needs an MRI KUB? 

Indications 

• Haematuria 
• Suspected renal mass or cyst 
• Congenital urinary tract anomalies 
• Ureteric stricture or obstruction 
• Recurrent urinary tract infections 
• Bladder wall pathology evaluation 

Patient Demographics: 

• Patients with known contrast allergies. 
• Younger aged patients or those who require frequent scans. 
• Pregnant patients (non-contrast scans). 
• Known patients with urinary tract abnormality. 

Benefits of an MRI KUB Test

• Use of radiation not required. 
• Very precise images of soft tissues. 
• Imposing no threat on consequent follow up imaging. 
• Proper imaging of the renal and bladder pathologies 

Conditions Diagnosed with MRI KUB

• Masses and cysts of the kidneys. 
• Ureteric stricture or obstruction. 
• Hydronephrosis. 
• Tumours of the bladder or thickening of bladder wall. 
• Developmental anomalies such as horseshoe kidneys. 
• Pyelonephritis or renal abscesses. 

Preparations for MRI KUB Test

• Do not eat for 4 to 6 hours before the scan if contrast will be used. 
• Drink water freely unless instructed otherwise. 
• Report any implants, pacemakers, or claustrophobia to the doctor. 
• Do not wear clothes or jewellery that contain metal. 

Pre-requisites 

• A renal function test if contrast is required. 
• clinical referral or summary from the physician. 
• Consent waiver for the use of contrast if not used. 

Best Time to Perform an MRI KUB 

• Before any surgical procedures or interventions. 
• When CT with contrast is not an option. 
• When the complex urinary system requires detailed evaluation. 

Eligibility for MRI KUB 

• All age groups can be enrolled. 
• Can be used during pregnancy so long as no contrast is used. 
• Those with MRI incompatible implants are excluded. 

MRI KUB Test Procedure 

• Supine positioning of patient on the MRI table. 
• Coils meant for the abdomen are placed over the kidney and bladder regions. 
• No initial image capturing is done with contrast. 
• If necessary, Gadolinium contrast may be administered at this stage. 
• Monitoring of patient is done afterwards, while the scan takes 30 to 45 minutes. 

Caution During the MRI KUB 

• Any cases of implanted metals and claustrophobia should be voiced right away. 
• A functional kidney is essential to the use of contrast. 
• Remain motionless to prevent distortion.
