Se hela listan på mayoclinic.org 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). Any deviation from protocol MUST be radiologist approved. Rad Director will be notified if this occurs without prior approval 2019-12-17 · CT urography (CTU) has become the primary examination for imaging the kidneys, ureters and bladder. It allows visualisation of the whole urinary tract and the detection of a variety of benign and malignant abnormalities, including calculi, renal tubular ectasia, papillary necrosis, congenital abnormalities, renal masses, and transitional cell carcinomas (TCC) [1,2,3,4,5,6,7]. Background: Since computed tomography (CT) urography began to replace excretory urography as the primary imaging technique in uroradiology, the collective radiation dose to the patients has increased.Purpose: To examine the changes in the CT urography protocol for investigating suspected urinary tract malignancy between the years 1997 and 2008, and how these changes have influenced the mean Se hela listan på appliedradiology.com Se hela listan på emedicine.medscape.com 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 prior history of cancers of the urinary collecting system and to identify abnormalities in patients with recurrent urinary tract infections. Three‐phase CT urography protocol resembles conventional IV urography in that the examinations consist of an unenhanced, nephrographic and excretory phase (Fig.

The representative CT urography protocols for the evaluation of upper urinary tract are three‐phase acquisition with a single‐bolus injection and two‐phase acquisition with a single‐bolus injection (split bolus injection; Fig. 2a,b). Most institutions use 3–6 phase CT urography protocols (80 %, median DLP 1793−3618 mGy.cm) which were associated with 2.4–4.9-fold higher dose compared to 2-phase protocol (20 %, 740 mGy.cm) (p < 0.0001).

CT urography (CT-U) is an established method, which allows assessment of urological malignancies. The study presents a novel protocol of 68 Ga-PSMA-11 PET/CT-U in PS and BCR of PC. Methods: A retrospective review of PSMA PET/CT-U preformed on 57 consecutive patients with prostate cancer.

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. Selected images from a CT Urography protocol CT. 8a is an axial CT image from the renal parenchymal phase. There is a mildly enhancing soft tissue mass in the left renal pelvis (arrow) consistent with a transitional cell carcinoma. CT, it can enhance tissue and calculi charac-terization [22–27].
