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 (Fig 1).

18 Oct 2018 However, a major drawback of CTU is that the radiation dose is high owing to its multi-phasic imaging protocol, including precontrast,

Typically, an EU includes one or more images of the abdomen before an IV contrast medium is administered (referred to as scout “ 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 CT, it can enhance tissue and calculi charac-terization [22–27].

Conclusion: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography. Key points: • To improve excretory phase imaging, an intravenous injection of furosemide should be performed before the injection of iodinated contrast medium.

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 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 ). 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.
