But with IVP, the dye is injected into a vein instead. Two major approaches to CT urography have been developed. The examination of a dilated ureter requires the use of the imaging method known as CT urography. With the recent introduction of multi–detector row helical computed tomography (CT), the radiologic evaluation of patients with urologic disease has changed rapidly. CT urography is an excellent technique for the evaluation of urinary tract calculi and renal masses, having high sensitivity and specificity for both conditions because it facilitates multiplanar imaging of the urinary system. Materials and methods: Fifty-nine examinations were performed in 53 pediatric patients and the degree of obstruction assessed using the renal transit time. There is also an increased incidence in. This modality is rapid and cost effective for screening animals with suspected urinary tract disease.

Objectives: To develop technical guidelines for computed tomography urography. The first approach combines axial CT with timed excretory urography (EU) performed by using conventional radiography, digital radiography, or CT scanned projection. Several techniques have been developed to measure the DRF with MRI by using the area under the time-intensity curve obtained from either a single slice, or a few slices, with a separate volume measurement [10, 27, 44,45,46].

The purpose of this study was to determine whether a saline bolus during CT urography improves urinary collecting system opacification and whether the addition of enhanced CT digital radiography (CTDR) improves urinary collecting system visualization with or without a saline bolus. 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. All kinking was either at or above the level of the CP. Renal papillary necrosis is not a pathologic entity but rather a descriptive term for a condition—necrosis of the renal papillae—that has various possible causes. Although it was originally performed using plain radiographic techniques, advanced imaging modalities have been progressively refined such that computed tomography (CT) and/or magnetic resonance imaging (MRI) have largely replaced excretory urography (EU) as. The term is most often encountered in ' intravenous pyelography ' (or "IVP"). Ureteroceles are characterized by dilation of the submucosal ureter segment within the bladder.
