Just prior to scanning the patient, give 1-2 cups of water in order to distend the stomach. Split bolus technique: The patient is given 35 mL of intravenous contrast and 100 mL saline after the non-contrast exam, but prior to the imaging of the mixed nephrographic/exretory ("Urogram") phase. Various scanning techniques for CT urography have been described, but there is no universally accepted imaging protocol (3, 4). In the most general sense, complete CT urography includes a nonenhanced phase, a contrast-enhanced phase, and an excretory phase (Fig 1).
It also is important to determine whether CT urography is the appropriate imaging modality. Depending on the clinical scenario, multiple phases may not be required, and therefore the radiation dose can be reduced . For example, single-phase nonenhanced CT (not CT urography) is generally adequate to diagnose stones in the acute clinical setting.

CT Urography Protocol at Our Institution — The standard CT urography protocol at our institution is summarized in the , Table. Precontrast images consist of plain abdominal radiographs and unenhanced CT scans (LightSpeed QX/i; GE Healthcare).
For example, single-phase nonenhanced CT (not CT urography) is generally adequate to diagnose stones in the acute clinical setting. “The CT urogram is most commonly performed as a three- phase computed tomography technique used to evaluate the kidneys and urinary collecting system. The three phases most commonly include a non-contrast phase, a nephrographic phase scanned at 80 to 120 s delay, and an excretory phase scanned at 10–15 min delay.” studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol). CT urography is defined as CT examination of the kidneys, ureters and bladder with at least one series of images acquired during the excretory phase after intravenous contrast administration. 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. CT urography (CT-U) is an established method, which allows assessment of urological malignancies. The study presents a novel protocol of 68Ga-PSMA-11 PET/CT-U in PS and BCR of PC. METHODS: A retrospective review of PSMA PET/CT-U preformed on 57 consecutive patients with prostate cancer.
