Computed tomography (CT) urography use CT images after intravenous contrast material to obtain images of the urinary tract. CT urography (CTU) is used as primary imaging techniques the evaluation of hematuria, which is blood in the urine, to follow patients with prior history of cancers of the urinary collecting system and to identify abnormalities in patients with recurrent urinary tract

CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma. Initial imaging includes a noncontrast phase to detect renal calculi as a source of hematuria.

The venous phase image (Fig. 3) also showed the fracture well. The CT urogram image showed the injury to the lower pole calyx (Fig. 4) and mild extravasation. Ct Urography: an Atlas [Silvermand] on *FREE* shipping on qualifying offers.

Patients can be asked to void completely prior to CT urography. Alternatively, patients can be asked to roll over on the CT table several times and/or to ambulate just prior to excretory phase image acquisition. CT urography is generally carried out with iodine contrast media, but in patients with contraindications to iodine, trypanophobia and lack of funds, CT urography fails. CT urography in the urinary bladder: To compare excretory phase images using a low noise index and a high noise index with adaptive noise reduction filter Nobuyuki Takeyama, Yoshimitsu Ohgiya, Takaki Hayashi, Toshiyuki Takahashi, Suzuki Yoshiaki, Daisuke Takasu, Junya Nakashima, Kyoichi Kato, Yuko Kinebuchi, Toshi Hashimoto, and Takehiko Gokan This prospective study of 100 patients with urinary stones (as seen on true non-enhanced images) showed that split-bolus dual-energy CT urography was technically feasible, with better quality of virtual non-enhanced images (lower image noise and improved iodine subtraction) on 100/140 kVp setting compared to 80/140 kVp setting, both settings utilising tin filtration. OBJECTIVE: The purpose of this study is to prospectively compare the image quality of and confidence in the presence of a lesion on CT urography images acquired using filtered back projection (FBP) with 100% and 50% radiation doses with those for images simultaneously acquired using sinogram-affirmed iterative reconstruction with strength 3 (SAFIRE) with 50% and 25% radiation doses for Discussion: As with excretory urography, the differential diagnosis for filling defects includes tumor, blood clot, and fungus ball; however, stone is unlikely because nearly all urinary tract calculi are of high CT attenuation (appearing similar to that of contrast-enhanced urine in the bladder lumen on excretory phase CT urographic images). contrast CT images.

•When it should be BWH CT Urography Protocol. 64 – Channel MDCT Feb 11, 2014 It has been historically diagnosed with intravenous pyelography (IVP), which is falling out of favor as an imaging modality. CT urography (CTU) Jul 3, 2015 PDF | For decades, traditional IVU studies have been the mainstay in the investigation of urinary tract calculi and obstruction. However, they CT urography (CTU) is an imaging study that is tailored to improve visualization of both the upper and lower urinary tracts. There is variability in the specific What are CT Urogram scans? A CT Urogram of the kidneys and bladder are called a CT KUB or urinary tract CT. This type of scan can find kidney stones, Total time – 3 -4 hrs approx.

Volume 35, Number 3, Pages 709 – 726. The information on this page is based on literature searches and specialist checking. We used many references and there are too many to list here. Discussion: Large urothelial neoplasms may be detected on axial CT urography images in both opacified and unopacified portions of the bladder. These masses are often, but not always, seen on three-dimensional reconstructed images.

CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma. Before the procedure, a person is often asked about things that might put them at risk - for example pregnancy or an allergy to contrast.
