You have a CT scan of your: kidney; bladder; tubes that connect the kidneys to your bladder (ureters) A CT scan uses x-rays to take detailed pictures of your body from different angles. A CT urogram is a test using a CT scan and special dye (contrast medium) to look at the urinary system. The contrast medium helps show up the urinary system more clearly. You have a CT scan of your: kidney.

Contrast agents for both CT and MRI are an extremely safe group of drugs and adverse side effects rarely develop. Contrast-enhanced axial CT scan: (A) showing an enhancing mass in the upper and mid pole of the right kidney. CT urogram using volume rendering (B) showing distortion of the calyces by the mass lesion; CT urogram using MIP technique (C) showing splaying, distortion of the calyces on the right side –right renal cell carcinoma In light of this basic physical assumption, iodinated contrast medium can be completely subtracted to obtain virtual unenhanced images and one of the main purposes of unenhanced images during CT urography (i.e., urinary calculi detection) could be achieved without requiring an unenhanced scan, therefore significantly cutting the radiation dose exposure [33, 36, 37]. A dye that contains iodine (contrast material) is often injected into the blood (intravenously) during a CT scan. The dye makes blood vessels and certain structures or organs inside the body more visible on the CT images. If an abdominal CT scan is performed, a contrast material is usually given by mouth (orally).

Urography ct scan contrast

The kidneys pass the dye into the urinary tract, which makes the ureters and bladder more visible. Then a CT-scan or an x-ray of the abdomen is taken.

The reasoning for using CT urography to investigate hematuria is based on its high diagnostic accuracy for urothelial cell carcinoma (UCC) and favorable comparison with other imaging techniques. Our CT urography protocol incorporates the use of digital scout images obtained immediately after the contrast-enhanced abdomen and pelvis phases, to augment the likelihood of visualizing the entirety of the ureters , with only a minimal incremental increase in radiation dose, which is far less than an additional CT pass would incur. The European Society of Urogenital Radiology defines CT urography as a diagnostic examination optimized for imaging the kidneys, ureters, and bladder with thin-slice MDCT, IV administration of contrast medium, and image acquisition in the excretory phase .
