Various scanning techniques for CT urography have been described, but there is no universally accepted imaging protocol (3,4). In the most general sense, complete CT urography includes a nonenhanced phase, a contrast-enhanced phase, and an excretory phase . studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol).

It is necessary for the radiologist to recognize the wide range of anatomical variants and ureteral diseases, in order to limit the diagnosis. CT urography uses X-rays to generate multiple images of a slice of the area in your body that is 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. FIGURE 8.

Radiation Protection in the 2000s - Julkari

Intravenous urography (IVU), also referred to as intravenous pyelography (IVP) or excretory urography (EU), is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and the urinary bladder. This exam has been largely replaced by CT urography. Terminology MATERIAL AND METHODS: The study was based on 102 patients (mean age 66.1+/-14.8 years, range 31-89 years; 30 female, 72 male) divided into five groups (groups A-E) corresponding to the time points at which changes were made to the CT urography protocol. The mean effective doses were estimated using the ImPACT CT Patient Dosimetry Calculator.

Precontrast images consist of plain abdominal radiographs and unenhanced CT scans (LightSpeed QX/i; GE Healthcare). CT UROGRAM / HEMATURIA PROTOCOL: NOTES: • Use at least 22g needle • Follow GFR and Metformin protocols for contrast studies • LMP on pts of child-bearing age The optimal combination of unenhanced, corticomedullary phase and nephrographic phase imaging depends on the context; suggestions of protocols are provided for eight different clinical situations. Conclusion: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography.

CT examination of the pancreas should always be done with maximum amount of contrast at a maximum flow rate, because both small pancreatic carcinomas aswell as pancreatic necrosis in pancreatitis are difficult to detect. It is a matter of personal flavor to do the whole abdomen at 35 sec p.i. or at 70 sec p.i. In this protocol, the total contrast agent dose is divided into two, which is known as the split bolus injection technique Cited by: CT urography results in a higher radiation exposure than excretory urography [13, 33]. The effective dose of CT urography protocol in our study (approximately 20 mSv) was times that of excretory urography ( mSv). CT urography: definition, CTU may be used as a problem-solving examination.
