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. 2 a). This protocol allows the complete evaluation of most common urological causes of hematuria, that is, calculi, renal masses and urothelial tumors, and might be the most widely used.

The most common protocol is a three-phase technique, which PDF | The aim was to develop clinical guidelines for multidetector computed tomography urography (CTU) by a group of experts from the European Society. Triple phase and split bolus techniques are most commonly used CTU protocols that consist of a non-contrast, nephrographic, and excretory phase, obtained by 23 Mar 2021 The procedure involves injecting a special dye into a vein in the hand or arm.

The French Society of Genitourinary Imaging organised a Delphi consensus conference with a two-round Delphi survey followed by a face-to-face meeting. Consensus was strictly defined using a priori criteria. Forty-two expert uro-radiologists completed both survey rounds with no attrition between the rounds.

CT urography can What is a CT urogram? A CT urogram is a type of CT scan. It looks at the kidneys, ureters and bladder. A CT scan takes About the Scan – CT Urography. SMIL performs CT urography after intravenous contrast material is used to obtain images of the urinary tract.

Conclusion: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography. During a CT urogram. For a CT urogram, you usually lie on your back on an exam table, though you may be asked to lie on your side or stomach. Straps and pillows may be used to help you maintain the correct position and keep still during the exam.

Radiologists have used the imaging techniques of excretory urography to develop CT urographic protocols. A typical CT urographic protocol has three phases that allow complete evaluation for the most common urologic causes of hematuria, that is, calculi, renal masses, and urothelial tumors (Fig. 1A, 1B ). 2016-06-20 · CT Urogram - Thin sagittal and coronal (3mm x 3mm) of the entire data set, and thick slab (3cm x 3mm) coronal MPR reconstruction should be performed of the opacified renal pelvis, ureters, and bladder. 3D of the collecting system can be performed, as needed or requested.
