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 .

Se hela listan på pubs.rsna.org 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. Radiologists have used the imaging techniques of excretory urography to develop CT urographic protocols.

A differential approach using a one-, two- or three-phase protocol is proposed, Se hela listan på en.wikipedia.org CT urography: Definition, indications and techniques. A guideline for clinical practice. whereby the clinical indication and the patient population will determine which CTU protocol is employed. CT Urography (CTU) • CTU is a multiphase CT examination in which the clinical presentation will largely determine the protocol used. • Because of the multiphasic and functional nature of CTU, the radiation dose can reach high levels, so suggestions for optimized use of CTU with reduced dose have been published by scientific societies. 17.
