4.9 ). CT Urography. If your physician has ordered a CT urography exam, you should wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the procedure. 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. Dual-energy CT urography is an emerging technique that allows a single contrast-enhanced acquisition phase with the creation of virtual nonenhanced images.

CT. The anonymised images Paper IV evaluated the impact of slice thicknesses in CT images of image quality and pathology between the three phases of a CT Urography (CTU) protocol In this study we have included the examination groups MRI, CT, ultrasound, at one site, for each brain MRI, the number of images and examination size in kilobytes (Kb) Urography: Intravenous urography as total number of examinations; Strålskydd för patientens strålkänsliga organ vid CT-undersökningar.

CT urography (CTU or CT-IVU) has now largely replaced traditional IVU in imaging the genitourinary tract. It gives both anatomical and functional information, albeit with a relatively higher dose of radiation. The aim is to illustrate the collecting systems, ureters and bladder with intravenous contrast, albeit in a single acquisition as opposed to the multiple and more dynamic traditional IVU.

När denna forskning inte räcker, utför ultraljudsdisposition, excretory urography, computed tomography. Vid ultraljud (1) och CT (2, 3) är njurens kontur vågig.

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.

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).
