This article reviews the principles, indications, and pitfalls of intravenous urography, and provides examples of normal and abnormal findings. Hello Everyone! My name is Meaghan Piretti and I am a professor for the radiologic technologist program at a community college. A retrograde pyelogram (RPG) is an imaging test that uses contrast dye in your urinary tract to take a better X-ray image of your urinary system. 2. The aim was to develop clinical guidelines for multidetector computed tomography urography (CTU) by a group of experts from the European Society of Urogenital Radiology (ESUR). It exposes you to a small dose of ionizing radiation to produce pictures of the inside of the body. MR urography (MRU) can be used to thoroughly evaluate the renal parenchyma, the pelvicaliceal system, and the rest of the urinary tract in a single imaging study as in CT urography [ 1] but without radiation exposure and IV contrast administration. Recommended IV dose: 100-150 mL. This allows assessment of the position, size, shape and internal architecture of the organ that was not apparent on the original radiograph. CT urography (CTU) is now the standard radiology investigation for patients presenting with unexplained haematuria, where there is a potential renal or post renal cause. I teach positioning courses. Background: Functional MR urography (fMRU) has developed into an innovative, radiation-free option for assessing parameters of kidney function in pediatric radiology. MR urography (MRU) can be used to thoroughly evaluate the renal parenchyma, the pelvicaliceal system, and the rest of the urinary tract in a single imaging study as in CT urography [ 1] but without radiation exposure and IV contrast administration. The first approach combines axial CT with timed excretory urography (EU) performed by using conventional radiography, digital radiography, or CT scanned projection. つまぐ （@rurigraph）さんの人気ツイート（新しい順）.

In children, MRU allows for high tissue contrast and high spatial resolution without. Making wise treatment decisions and planning treatments. However, the utility of CT urography is heavily contingent on the use of proper image acquisition protocols. It is also useful for detailed examination of the pelvicaliceal collecting system and ureters to check for injury, stricture, or fistula. Images are made using a CT-scan ( CT urography) or x-rays ( intravenous urography, or IVU). Most three-phase MDCTU protocols comprise an initial non-contrast phase to detect urinary tract calculi and a second phase, i. CT urograms use imaging and contrast dye to allow doctors to diagnose problems such as kidney and bladder stones, certain cancers, and structural irregularities. The high contrast and spatial resolution afforded by CT allow detection and evaluation of subtle differences in very small structures. Xanthogranulomatous pyelonephritis is seen essentially in all age groups, but most frequently presents in middle-aged to elderly patients 1,5.

Tuberculosis (TB) remains a worldwide scourge and its incidence appears to be increasing due to various factors, such as the spread of human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). This modality is rapid and cost effective for screening animals with suspected urinary tract disease. In light of these applications, CT is recognized as the most sensitive and specific test for the diagnosis of urinary calculi (Fig. Patients with risk factors, without any of the following: history of recent vigorous exercise, or presence of infection or viral illness, or present or recent menstruation,Renal imaging has become a fundamental part of clinical care for patients with kidney disease. Most patients with medullary sponge kidney remain asymptomatic throughout life, with the diagnosis only made incidentally when the renal tract is imaged for other reasons. CT urograms use imaging and contrast dye to allow doctors to diagnose problems such as kidney and bladder stones, certain cancers, and structural irregularities. 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. On CT, the rate of the radiologically "significant" kinking classified into either Grade 2 or 3 was 18. Some reserve the term "pyelography" to refer to retrograde opacification of the collecting system. Duplication occurs when 2 separate ureteric buds arise from a single Wolffian duct. ”. Clinical use.

Also known as intravenous urography, healthcare providers use intravenous pyelogram to diagnose problems in your kidneys, ureters and bladder. However, this examination may present technical problems influencing further results. A summary document was produced and discussed at the ESUR 2006 and ECR 2007. An ectopic ureter is a congenital renal anomaly that occurs as a result of abnormal caudal migration of the ureteral bud during its insertion to the urinary bladder. CT angiography of the chest (CTA chest) is a cross-sectional diagnostic examination that can be performed ECG-gated or non-ECG gated. CT urography is an excellent technique for the evaluation of urinary tract calculi and renal masses, having high sensitivity and specificity for both conditions because it facilitates multiplanar imaging of the urinary system. ”. 04.
