What is a MRA RENAL(NON CONTRAST)?

MRA Renal (Non-Contrast) is a specialized MRI angiography examination that provides detailed imaging of the renal arteries without intravenous contrast to evaluate narrowing, reduced blood flow, blockages, aneurysms, and other vascular abnormalities affecting the kidneys, supporting accurate diagnosis and clinical management.

FAQs

Who may need MRA Renal (Non-Contrast)?

MRA Renal (Non-Contrast) may be recommended for patients with suspected renal artery narrowing, reduced blood flow to the kidneys, difficult-to-control blood pressure, or other suspected renal vascular abnormalities, particularly when contrast administration is not desirable.

Is MRA Renal (Non-Contrast) useful in patients with high blood pressure?

Yes. When renovascular hypertension is suspected, imaging of the renal arteries may help determine whether arterial narrowing or another vascular abnormality could be contributing to elevated blood pressure.

Is MRA Renal (Non-Contrast) different from contrast-enhanced MRA?

Yes. Non-contrast MRA uses specialized MRI techniques to visualize blood vessels without an injected contrast agent, while contrast-enhanced MRA uses intravenous gadolinium to improve vascular visualization.

Do I need any preparation before MRA Renal (Non-Contrast)?

Preparation depends on the imaging centre's protocol. You may be asked to fast for a specified period or follow other instructions. Inform the MRI team about metallic implants, pacemakers, previous surgeries, pregnancy or possible pregnancy, and other implanted medical devices.

Will I need additional tests after MRA Renal (Non-Contrast)?

Depending on the findings, your doctor may recommend Doppler ultrasound, CT angiography, contrast-enhanced MRA, catheter angiography, renal function tests, or specialist evaluation.
