A single CT urogram carries no risk of developing cancer after radiation exposure. CONCLUSION. A CT protocol is a set of parameters that specify a specific exam and contrast delivery requirements. Nausea. PURPOSE: To evaluate image quality and dose for abdominal imaging techniques that could be used as part of a computed tomographic (CT) urographic examination: screen-film (S-F) radiography or computed radiography (CR), performed with moving and stationary grids, and CT scanned projection radiography (CT SPR). Transitional cell carcinoma is typically a tumor of older patients, with the average age of presentation being 65, and the majority of patients being over the age of 60 1. Over the past decade, computed tomographic (CT) urography has emerged as the primary imaging modality for evaluating the urinary tract in various clinical settings, including the initial workup of hematuria. A contrast medium is a substance that is administered to the patient that is either more radiopaque or more radiolucent than the surrounding tissue. The urographic examination should involve consultation between the referring physician and the radiologist. MRU is limited by longer examination times than for CT urography, decreased spatial resolution. Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture. Urography is a radiologic technique used for evaluation of the genitourinary system—specifically, the kidneys, ureters, and bladder. Imaging the urinary tract: Correct use of radiography and ultrasonography (Proceedings) Survey radiography is commonly used to image the urinary tract and provides information on size, shape, opacity, location and, margination of urinary organs. Some reserve the term "pyelography" to refer to retrograde opacification of the collecting system. CT urography ( CTU or CT IVU ), also known as CT intravenous pyelography ( CT IVP ), has now largely replaced traditional IVU in imaging the genitourinary tract. Which of the following additional findings should the nurse.

Epidemiology. Acute renal colic with resultant flank pain is a common and sometimes complex clinical problem. With the recent introduction of multi–detector row helical computed tomography (CT), the radiologic evaluation of patients with urologic disease has changed rapidly. The renal medulla and papillae are vulnerable to ischemic necrosis because of the peculiar arrangement of their blood supply and the hypertonic environment. Abstract. As such, there have been extensive. hematuria. Although it was originally performed using plain radiographic techniques, advanced imaging modalities have been progressively refined such that computed tomography (CT) and/or magnetic resonance imaging (MRI) have largely replaced excretory urography (EU) as. The purpose of this study was to determine whether a saline bolus during CT urography improves urinary collecting system opacification and whether the addition of enhanced CT digital radiography (CTDR) improves urinary collecting system visualization with or without a saline bolus. 5.

Urothelial carcinoma (UC) is the fourth most frequent tumor in Western countries and upper tract urothelial carcinoma (UTUC), affecting pyelocaliceal cavities and ureter, accounts for 5–10% of all UCs. As an imaging study, it combines anatomic accuracy with qualitative information regarding renal function and obstruction. A series of X-ray pictures is then taken at timed intervals. CT angiography of the chest (CTA chest) is a cross-sectional diagnostic examination that can be performed ECG-gated or non-ECG gated. The high contrast and spatial resolution afforded by CT allow detection and evaluation of subtle differences in very small structures. Materials and methods: We. ”.
