CT urography (CTU) and MR urography (MRU) are used as primary imaging techniques to evaluate patients with blood in the urine (hematuria), follow patients

A CT Urogram is a CT exam that takes very thin slice (5mm) images of the urinary system, starting just above the kidneys and ending just below the pubic bone.

At Main Street Radiology, our hematuria protocol involves images from a 3D CT urogram, as well as traditional high-resolution CT images of the kidneys. CT urography is currently the first-line imaging modality for several indications, including hematuria, initial staging of urothelial tumors, and follow-up surveillance in patients with prior urothelial tumors (5 – 9) (Table 1). A good example of a normal CT-IVU study. The chief indication is for the assessment of hematuria.

These masses are often, but not always, seen on three-dimensional reconstructed images. In this case, urothelial neoplasm is the most likely diagnosis, given the rounded and lobulated appearance. 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].

It gives your doctor information about diseases in the urinary tract.

SMIL performs CT urography after intravenous contrast material is used to obtain images of the urinary tract. Urography images A Computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected The CT urogram is a radiological test to explore possible reasons for blood in the urine or other symptoms. This specialized scan uses intravenous (IV) contrast Oct 22, 2017 CT urogram: Non-contrast axial computed tomographic (CT) scan of the abdomen and pelvis is routinely obtained as part of a CT urogram to look A CT Urogram is a CT exam that takes very thin slice (5mm) images of the urinary system, starting just above the kidneys and ending just below the pubic bone.

In order to do this, several measures may be taken to minimize the amount of unopacified urine in the bladder. Patients can be asked to void completely prior to CT urography. Alternatively, patients can be asked to roll over on the CT table several times and/or to ambulate just prior to excretory phase image acquisition.

OBJECTIVE: The purpose of this study is to prospectively compare the image quality of and confidence in the presence of a lesion on CT urography images acquired using filtered back projection (FBP) with 100% and 50% radiation doses with those for images simultaneously acquired using sinogram-affirmed iterative reconstruction with strength 3 (SAFIRE) with 50% and 25% radiation doses for Discussion: As with excretory urography, the differential diagnosis for filling defects includes tumor, blood clot, and fungus ball; however, stone is unlikely because nearly all urinary tract calculi are of high CT attenuation (appearing similar to that of contrast-enhanced urine in the bladder lumen on excretory phase CT urographic images). contrast CT images. On the background of a shift in preference towards CT, we now turn our attention to CT urography, which is essentially contrast-enhanced CT evaluation of the urinary tract. CT The CT urogram showed clearly the lower pole fracture in the arterial phase (Fig. 1), with intact upper and lower polar arteries on the angiogram (Fig.

Aug 1, 2008 Must Imaging Always Be Performed? Radiologic Work-up of Hematuria; Increasing Role of CT Urography; Role of Ultrasonography and MRI CT urography (CTU) is an imaging method tailored specifically for the evaluation of the upper urothelial tract and urinary bladder. High diagnostic accuracy in ureter. CT (Computed Tomography) Urography is a diagnostic examination which is optimized for imaging the kidneys, ureters and bladder with thin slice MDCT Magnetic resonance urography, also known as (MRU) is a type of (MRI) exam that uses contrast material to evaluate and detect blood in the urine, kidney or Computed tomography (CT) urography use CT images after intravenous contrast material to obtain images of the urinary tract.

3) also showed the fracture well. The CT urogram image showed the injury to the lower pole calyx (Fig. 4) and mild extravasation.

Normal CT intravenous urogram. 1 article features images • The ESUR defines CT urography (CTU) as a diagnostic examination optimized for imaging the kidneys, ureters and bladder with thin-slice Multidetector CT, administration of intravenous contrast medium, acquisition of images in the excretory phase with multiplanar imaging of the urinary system. CT urography uses X-rays to generate multiple images of a slice of the area in your body that is being studied, including bones, soft tissues, and blood vessels.
