Magnetic urography is a non-invasive imaging examination that uses magnetic resonance imaging (MRI) to provide detailed visualization of the urinary system, primarily the kidneys, renal collecting systems, ureters, and the urinary bladder.
Unlike CT urography, it does not use ionizing radiation, making it a safer option, especially for children, pregnant women, or individuals who are sensitive to radiation. It offers excellent soft tissue imaging and is suitable for long-term follow-up.
Magnetic urography is indicated for:
- Anatomical imaging and detection of congenital anomalies of the urinary tract
- Evaluation of obstructions in the ureters
- Investigation of hydronephrosis
- Monitoring of tumors or cysts
- Assessment of postoperative complications
- As an alternative for patients who cannot receive iodine-based contrast (as used in CT scans)
Procedure
The patient is placed inside the MRI scanner. Depending on the case, an MRI contrast agent (gadolinium) may be administered, mainly to improve the visualization of tumors or blood vessels. The scan may include a series of images, either with or without contrast.
