What is an MRI Urogram?
Magnetic resonance urography (MRU) is a radiation-free exam that uses magnetic waves to create detailed pictures of the kidneys, ureters and bladder. It is a radiation-free way to look at the structure and function of the urinary tract, which is the part of the body that produces and transports urine.
What does a CT urography show?
A CT urogram is used to examine the kidneys, ureters and bladder. It lets your doctor see the size and shape of these structures to determine if they’re working properly and to look for any signs of disease that may affect your urinary system.
How long is a MRI Urogram?
Comprehensive MR Urography Protocol A comprehensive “one-stop shop” type of protocol, such as the one shown in the ,Table, can take between 30 and 60 minutes for an average technologist to complete depending on the choice of sequences and the available equipment.

How urography is performed?
What is the current role of CT urography and MR urography in the evaluation of the urinary tract?
CT urography provides a detailed anatomic depiction of each of the major portions of the urinary tract—the kidneys, intrarenal collecting systems, ureters, and bladder—and thus allows patients with hematuria to be evaluated comprehensively.
How is IVP performed?
In an IVP exam, an iodine-containing contrast material is injected through a vein in the arm. The contrast material then collects in the kidneys, ureters and bladder, sharply defining their appearance in bright white on the x-ray images. X-ray images are typically stored as digital images in an electronic archive.
What is a CT urogram with and without contrast?
In general, during a CT urogram: A doctor will first conduct a non-contrast scan. This can show kidney stones and any major structural irregularities. They will then inject the contrast, and a second scan will show the soft tissue of the kidneys, bladder, and adrenal glands in enhanced detail.
