A computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein. In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system.
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. Initial imaging includes a noncontrast phase to detect renal calculi as a source of hematuria.

Voiding cystourethrography. In urology, voiding cystourethrography ( VCUG) is a frequently performed technique for visualizing a person's urethra and urinary bladder while the person urinates (voids). It is used in the diagnosis of vesicoureteral reflux (kidney reflux), among other disorders. [1] The technique consists of catheterizing the ...
Cystography image showing contrast in the urinary bladder and left ureter (right side of image). In radiology and urology, a cystography (also known as cystogram) is a procedure used to visualise the urinary bladder . Using a urinary catheter, radiocontrast is instilled in the bladder, and X-ray imaging is performed.
Imaging studies, such as an intravenous urogram (IVU), renal ultrasonography, CT, or MRI, are also important investigations in determining the presence and/ or cause of hydronephrosis. Whilst ultrasound allows for visualisation of the ureters and kidneys (and determine the presence of hydronephrosis and / or hydroureter), an IVU is useful for ...
A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists.
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. Computed tomography provides an overall better surgical strategy planning, and possibly fewer unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. Projections
X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source.
