About the Scan – CT Urography. SMIL performs CT urography after intravenous contrast material is used to obtain images of the urinary tract. Urography images are used to evaluate issues or detect abnormalities in portions of the urinary tract, including the kidneys, bladder and ureters, including:

Furosemide improves the urinary tract and ureteral opacification and distension (Silverman et al. 2006 ) with a greater effect than saline by increasing the urinary flow rate and the delivery of contrast medium to the middle and distal ureter. Conclusion: CT urography with abdominal compression results in reliable opacification of the collecting system that is comparable with opacification seen on IV urography. In patients with abnormalities, reformatted images were a useful adjunct to axial images. CT urography has potential as an imaging tool for the urothelium.

konventionellt utförd på utsöndrings urogram eller på beräknade tomogram med kontrastförbättring. CT urography uses X-rays to generate multiple images of a slice of the area in your body being studied, including bones, soft tissues and blood vessels. These images are then sent to a computer and quickly reconstructed into very detailed, 2-D images. Computed tomography (CT) urography and magnetic resonance (MR) urography use CT and MR images, respectively, after intravenous contrast material to obtain images of the urinary tract. CT urography (CTU) and MR urography (MRU) are used as primary imaging techniques to evaluate patients with blood in the urine (hematuria), follow patients with The total effective dose of the “standard” CT urography examination, which comprises five film images (scout image, 8-, 10-, and 20-minute delayed images, and postvoiding image) and CT scans of the abdomen and pelvis with and without intravenous contrast material, is estimated to be 24.5 mSv. About the Scan – CT Urography SMIL performs CT urography after intravenous contrast material is used to obtain images of the urinary tract. Urography images are used to evaluate issues or detect abnormalities in portions of the urinary tract, including the kidneys, bladder and ureters, including: Hematuria (blood in urine) CT urography (CTU or CT-IVU) has now largely replaced traditional IVU in imaging the genitourinary tract.

Computed tomography (CT) urography use CT images after intravenous contrast material to obtain images of the urinary tract. With the advent of the multi-detector CT, high-resolution 3D images of the collecting systems and ureters can be obtained.

Split-bolus CT urography with synchronous nephrographic and excretory phase in dogs: comparison of image quality with three-phase CT urography and optimal allocation ratio of contrast medium J Vet Sci. 2020 Jul;21(4):e55. doi: 10.4142/jvs.2020.21.e55. Authors

Dual-energy CT (DECT) imaging can reconstruct virtual unenhanced CT (VUCT) images from contrast-enhanced CT images. As VUCT is equivalent to UCT in characterising renal masses, radiation dose to patients can be reduced during CT scans using dual-energy sources [4,5 CT urography (CTU) was introduced when multidetector-row computed tomography (MDCT) was already spread worldwide. The expanding use of CTU has resulted in an increase in both the frequency of procedures and patient radiation exposure (1, 2).Considering that the urinary tract is a high-contrast structure during the excretory phase (EP), substantial dose reduction may be possible while Kidney and urinary tract imaging: triple-bolus multidetector CT urography as a one-stop shop--protocol design, opacification, and image quality analysis.

These masses are often, but not always, seen on three-dimensional reconstructed images.

Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam.

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).
