Most three-phase MDCTU protocols comprise an initial non-contrast phase to detect urinary tract calculi and a second phase, i. CONCLUSION. 32. The most common vicarious excretion of water-soluble contrast material is via the liver, resulting in increased bile density seen in the gallbladder. 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. During embryogenesis, the pelviureteric junction forms usually around the fifth week and the initial tubular lumen of the ureteric bud. Appropriate therapy is ureteronephrectomy if the lesion is unilateral with secondary hydronephrosis and.

Computed tomography (CT) urography is the best noninvasive method of evaluating the upper urinary tract for urothelial malignancies. It is similar to a voiding cystourethrogram (VCUG), and the difference between the studies is primarily one of emphasis; a cystogram focuses on the bladder and a VCUG focuses on the posterior urethra. CTU included true non-enhanced phase, dual-energy mode. CT urograms use imaging and contrast dye to allow doctors to diagnose problems such as kidney and bladder stones, certain cancers, and structural irregularities. Purpose: To evaluate if measurement of split renal function ( SRF split renal function ) with dynamic contrast material-enhanced ( DCE dynamic contrast enhanced ) magnetic resonance (MR) urography is equivalent to that with renal scintigraphy ( RS renal scintigraphy ) in patients suspected of having chronic urinary obstruction.

Urinary bladder cancer (UBC) is the 10 th most common diagnosed cancer in the world in 2020 []. Epidemiology. Urography Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract. The functions of the kidney are complex and include: (1) excretion of surplus water and the final metabolic products; (2) maintenance of the constant composition of body fluids; (3) preservation of the acid–base balance; and (4) endocrine function manifested as production and release of erythropoietin, renin and 1,25 dihydroxycholecalciferol. Multidetector (spiral) CT is now the dominant radiologic imaging modality for evaluation of the urinary tract and adrenal glands. Leyendecker, in Problem Solving in Abdominal Imaging, 2009 Magnetic Resonance Urography. OBJECTIVE. Overdistention and backflow from a kidney into the venous system may distort calyces and obscure details. MRI uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. With expansions in use of cross-sectional imaging, the computed tomographic (CT) nephrogram (ie, contrast material enhancement within the renal parenchyma) has assumed a greater role in the evaluation of urinary tract disorders. These features are distinct from non-enhancement of the. Magnetic resonance urography (MRU) is an important MRI application that provides noninvasive comprehensive morphological and functional evaluation of the kidneys and urinary tract.

The aim of this process was again to standardise paediatric uroradiologic imaging and to reduce invasiveness and radiation dose. There are two types of MR urography: static fluid-sensitive urography that is heavily T2-weighted to image the fluid-filled urinary system and excretory MR. Computerized tomography (CT) urogram: A computerized tomography (CT) urogram is an imaging exam used to evaluate your urinary tract, including your kidneys, your bladder and the tubes (ureters) that carry urine from your kidneys to your bladder. For some, this is a misnomer and a test that images intravenous contrast as it travels through the kidney parenchyma into the urinary collecting system should only be called. They are connected by an isthmus of either functioning renal parenchyma or fibrous tissue. 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. They are most often smooth, elongated, and cylindric, though they may also be short and frondlike. Because cystoscopy is considered. 有2000多个 单机游戏 的下载资源，站长珍藏的. 1007/s00276-016-1689-7.

This allows assessment of the position, size, shape and internal architecture of the organ that was not apparent on the original radiograph. These are rare injuries and are overlooked as other abdominal and pelvic injuries often take priority. Renal papillary necrosis is a clinicopathological entity where any or all of the papillae undergo selective necrosis that can be demonstrated either radiologically or histologically. Specifically, to address the efforts urologist should be making to reduce the use of ionizing radiation and to examine alternatives to computerized tomography (CT) scan in diagnosing and managing patients with stones.
