• 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.

The following document is an updated CT protocol for all of the sites at which TRA-MINW is responsible for the administration, quality, and interpretation of CT examinations. Include for ALL exams Iodinated contrast material (300 mgI/ml); 0.5 s rotation time. AEC w/ quality reference 200 mAs, 120 kVp. BWH CT Urography Protocol.

1-3 Noncontrast images extending from the top of the kidneys through the bladder are obtained to evaluate for calculi, fat-containing lesions and parenchymal calcifications, and to provide baseline attenuation for assessment of lesion enhancement. CT Urogram I-/I+ • 2 scans: Noncontrast, Combo Nephrographic/Excretory • Indications: • Optimized study to look at renal parenchyma AND collecting system –Microscopic hematuria –Detecting transitional cell carcinoma (TCC) • Not good for looking at renal (parenchymal based) mass or indeterminate cysts CT Protocols Conventional abdominal CT of the entire urinary tract can be augmented by delayed thin-section images of the contrast-opacified collecting systems, ureters, and bladder 18; the combined examination CT cystography is a variation of the traditional fluoroscopic cystogram.Instead of anterograde opacification of the urinary collecting system (as with CT urography), contrast is instilled retrograde into the patient's bladder, and then the pelvis is imaged with CT. 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.

CT urography acquisition and reconstruction parameters for GE X4 - 16 CT machines. phase CT urography protocol with a 120-kVp acquisition, compared with a mean effective dose of 5–10 mSv for IV urography.21,22,41,42 The split-bolus technique reduced radia-tion exposure by approximately 15–65% without reducing image quality.23,43,44 Other than the two-phase CT urography protocol, several preparation, indication, position and protocol of ct ivu/ ct ivp ( intravenous pyelogram) If any patient at a TRA-MINW outpatient facility requires CT re-imaging, obtain radiologist advice prior to proceeding with the exam. The following document is an updated CT protocol for all of the sites at which TRA-MINW is responsible for the administration, quality, and interpretation of CT examinations. Include for ALL exams CT urography (CT-U) is an established method, which allows assessment of urological malignancies.

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].

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. However, in the common sense, to exploit all the potential of this technique, CT urography is understood as a combination of renal CT plus CT of the contrast-enhanced upper urinary tract. Therefore, in most centers, a three-phase CT urographic protocol, consisting of unenhanced, nephrographic, and excretory phases, is performed [ 1 , 3 , 7 ]. Radiologists have used the imaging techniques of excretory urography to develop CT urographic protocols.
