a CT image contains both nephrographic- and excretory-phase information along with enhancing the renal parenchyma as well as the renal collecting system. Compared with the 3-phase technique, the split-bolus technique decreases radiation exposure to the patient by 30%–35% and reduces the number of CT images to be acquired [11,12].

Computed tomography (CT) urography and magnetic resonance (MR) urography use CT and MR images, respectively, after intravenous contrast material to obtain images of the urinary tract. 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 The total effective dose of the “standard” CT urography examination, which comprises five film images (scout image, 8-, 10-, and 20-minute delayed images, and postvoiding image) and CT scans of the abdomen and pelvis with and without intravenous contrast material, is estimated to be 24.5 mSv. About the Scan – CT Urography SMIL performs CT urography after intravenous contrast material is used to obtain images of the urinary tract. Urography images are used to evaluate issues or detect abnormalities in portions of the urinary tract, including the kidneys, bladder and ureters, including: Hematuria (blood in urine) CT urography (CTU or CT-IVU) has now largely replaced traditional IVU in imaging the genitourinary tract. It gives both anatomical and functional information, albeit with a relatively higher dose of radiation.

A CT Urogram of the kidneys and bladder are called a CT KUB or urinary tract CT. This type of scan can find kidney stones, Total time – 3 -4 hrs approx. · Patient history/consent: 5-10 mins · On table time - 30 mins · Observation time post scan – 5-10 mins CT urography (CTU) is an imaging modality with high diagnostic accuracy in the detection of UTUC and has replaced intravenous excretory urography and Although CT images are acquired with radiation, no radiation remains in a patient's body after a CT examination. X-rays used in standard CT exams have no The role of CT in imaging the urinary tract has expanded in recent years, particularly with the advent of multidetector (MDCT) scanners and CT urography ( CTU).

Det kan ibland bestämmas av en allmän analys av urin. När denna forskning inte räcker, utför ultraljudsdisposition, excretory urography, computed tomography.

You may be given a gown to wear during the procedure. Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam.

CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma. Before the procedure, a person is often asked about things that might put them at risk - for example pregnancy or an allergy to contrast.

Other forms of imaging of the kidney are used when stones Following Transurethral Bladder Surgery: Imaging with Figure 1 - Axial CT urogram excretory phase images show a lobulated mass along the left wall of the Feb 15, 2019 CT relies on x-rays for imaging, just like plain radiography and IV (Top right) Image from the patient's computed tomography urogram.
