During a CT urogram, an X-ray dye (iodine contrast solution) is injected into a vein in your hand or arm. The dye flows into your kidneys, ureters and bladder, outlining each of these body parts. X-ray pictures are taken at specific times during the exam, allowing your doctor can clearly see your urinary tract and look for any abnormalities. Urography Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract.
CT Urography is a newly developed, specialized type of CT scan using the latest multi-detector scanner. It is used primarily for patients with hematuria (blood in the urine). The most common causes of hematuria include kidney stones as well as possible tumors in the kidney, ureter and/or bladder. Previously, to fully evaluate the source of […] CT urography with a multi-detector row scanner and supplemental infusion of normal saline reliably displays the opacified urinary collecting system. Radiology . 2002 Dec;225(3):783-90.

However, in the common sense, to exploit all the potential of this technique, CT urography is understood as a combination of renal CT plus CT of the contrast-enhanced upper urinary tract. Therefore, in most centers, a three-phase CT urographic protocol, consisting of unenhanced, nephrographic, and excretory phases, is performed [ 1 , 3 , 7 ].

As a result, a number of new applications for multislice CT have recently been developed, one of which is CT urography. The motivation for performing CT urography is the desire to create a single imaging test that can completely assess the kidneys and urinary tract for urolithiasis, renal masses and mucosal abnormalities of the renal collecting system, ureters and bladder. CT hybrid urography This technique combines the advantages of CT in imaging the kidneys with those of contrast radiography in imaging the urinary collecting system; the advantage of this technique is that it does not need CT postprocessing procedures. If CT topography is used, the image quality of a CT topogram to view the urothelium is Computed tomography (CT) was used as a standard. EU/LT permitted det … A prospective blinded study of 201 patients was performed to determine the relative sensitivities and specificities of excretory urography/linear tomography (EU/LT) and ultrasound (US) for the diagnosis of renal parenchymal masses. Computed Tomography Urography. CT urography combines a noncontrast phase to diagnose hydronephrosis and urinary calculi, a nephrogenic phase to evaluate the renal parenchyma for pyelonephritis or neoplastic lesions, and an excretory phase to detect urothelial disease.
Computed tomographic (CT) excretory urography is commonly used to investigate canine ureteral ectopia (UE). Modern technology allows time‐resolved CT imaging (four‐dimensional CT excretory urography [4D‐CTEU]) over a distance exceeding the detector collimation.

It is used primarily for patients with hematuria (blood in Oct 1, 2004 CT urography is evolving and is a promising diagnostic examination that allows comprehensive evaluation of the urinary tracts. CT urography can Jun 1, 2014 Phases of enhancement · Non-enhanced CT (NECT) Helpful in detecting calcifications, fat in tumors, fat-stranding as seen in inflammation like CT Urogram requires: The patient should have nothing to eat or drink for a minimum of 3 hours prior to exam.
CT urography is a sophisticated, specialized radiological examination designed to evaluate the urinary tract (kidneys, ureters and bladder) using computed tomography (CT). This exam has been introduced to replace or complement the IVP (or excretory urogram). • The ESUR defines CT urography (CTU) as a diagnostic examination optimized for imaging the kidneys, ureters and bladder with thin-slice Multidetector CT, administration of intravenous contrast medium, acquisition of images in the excretory phase with multiplanar imaging of the urinary system.
