Main Street Radiology was the first practice in Queens to install a 16-detector spiral CT, which has the ability to scan up to 16 times faster than a traditional spiral CT. CT Coronary Angiography; CT Urography Magnetic resonance urography (MRU) can be used to thoroughly evaluate the renal parenchyma, the pelvicalyceal system, and the rest of the urinary tract in a single imaging study as in CT urography, and more specifically MRU is clinically useful in the evaluation of suspected urinary tract obstruction, hematuria, and congenital anomalies, as well as surgically altered anatomy. CT Upper Extremity - Glenoid Bone Stock and Version: CT: 8/28/2020: English: MR Brachial Plexus: MR: 8/28/2020: English: CT Lungenembolie (CT pulmonary embolism) CT, CH: 6/19/2020: German: CT KHK (CT coronary heart disease) CA, CT: 6/19/2020: German: CT Pankreaskarzinom, solide (CT pancreatic cancer, solid tumor) GI, CT: 6/19/2020: German: US In the developed world, however, it has increasingly been replaced by contrast computed tomography of the urinary tract (CT urography), which gives greater detail of anatomy and function. History. The technique of IVP was originally developed by Leonard Rowntree of the Mayo Clinic in the 1920s. CT of the kidneys: What size are renal cell carcinomas when they cause symptoms or signs? Scand J Urol Nephrol.

Study results suggest that CT urography has excellent sensitivity (89–100%) and specificity in the detection of pelvicaliceal and ureteric transitional cell carcinoma. Data have prompted investigators in the field to conclude that CT urography is more sensitive and specific than excretory urography in the detection of Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract. Urography with conventional x-ray is known as intravenous pyelogram (IVP). Urography is also often performed using computed tomography (CT) or magnetic resonance imaging (MRI). CT urography is a sophisticated, specialized radiological examination designed to evaluate the urinary tract (kidneys, ureters and bladder) using computed tomography (CT).

As a result, a number of new applications for multislice CT have recently been developed, one of which is CT urography. The motivation for performing CT urography is the desire to create a single imaging test that can completely assess the kidneys and urinary tract for urolithiasis, renal masses and mucosal abnormalities of the renal collecting system, ureters and bladder.

CT urography and MR urography are an evolving concept and developing technique. As the technology matures, CT urography will combine the ultimate diagnostic capabilities of intravenous urography Read "CT urography: a comparison of strategies for upper urinary tract opacification, European Radiology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Intravenous urography, ultrasonogra-phy, CT, retrograde ureterography and pyelography, cystoscopy, and ureteroscopy can all be used to evaluate patients with hematuria.

Clinical demographics and available thoracic computerised tomography (CT) imaging were detected from 139 PiZZ individuals identified from the Irish National

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. During any CT urography acquisition protocol, some tricks, such as abdominal compression (“compression CT urography”) or the injection of a saline chaser bolus, to improve the distension of the upper urinary tract can be adopted [15–17].

6. CT urography is generally carried out with iodine contrast media, but in patients with contraindications to iodine, trypanophobia and lack of funds, CT urography fails. Computed tomographic (CT) excretory urography is commonly used to investigate canine ureteral ectopia (UE).

The first approach combines axial CT with timed excretory urography (EU) performed by using conventional radiography, digital radiography, or CT scanned projection radiography (SPR). 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. During any CT urography acquisition protocol, some tricks, such as abdominal compression (“compression CT urography”) or the injection of a saline chaser bolus, to improve the distension of the upper urinary tract can be adopted [15–17]. Some authors suggest that a significant improvement in the opacification of the middle and distal ureters on the post-release excretory phase scan is achieved, whereas other authors report that no significant difference in ureteral distension exists on It is widely accepted that CT urography outperforms ultrasound, excretory urography, and radiography in the evaluation of renal parenchymal masses and urinary tract calculi.

CT Urography. If your physician has ordered a CT urography exam, you should wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the procedure. Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam.

2. Van Der Molen AJ et al. CT Oct 1, 2006 Many centers are now replacing conventional intravenous urography with an examination based on CT or MRI. MR urography includes Silverman, SG, Leyendecker, JR, Amis, ES. What is the current role of CT urography and MR urography in the evaluation of the urinary tract?
