Patient Radiation Dose at CT Urography and Conventional Urography
Radiology, 2004To measure and compare patient radiation dose from computed tomographic (CT) urography and conventional urography and to compare these doses with dose estimates determined from phantom measurements.Patient skin doses were determined by placing a thermoluminescent dosimeter (TLD) strip (six TLD chips) on the abdomen of eight patients examined with CT ...

Evaluation of patient effective doses in CT urography, intravenous urography and renal scintigraphy.
Radiation Protection Dosimetry, 2015Imaging of the renal system is performed with different techniques depending mainly on clinical symptoms and signs. This study intended to evaluate patient effective doses undergoing renal scintigraphy (technetium-99m-diethylene-triamine-pentaacetic acid)

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 ...

DANGERS OF EXCRETORY UROGRAPHY
Journal of the American Medical Association, 1960The diagnostic value of excretory urography justifies its extensive use provided its limitations are recognized and its dangers are appreciated. It should not become merely a routine study, and the exposure of the patient to radiation should be limited.

Urography is regarded as one of the best screening tests for evaluation of urinary tract disease and is commonly used in the search for a cause of hematuria or the presence of upper tract urothelial masses. It is also used in the evaluation of patients with trauma, known or suspected urolithiasis, or renal infection and for the documentation of ...

MR urography represents the next step in the evolution of uroradiology in children by combining superb anatomic imaging with quantitative functional evaluation in a single examination that does not use ionizing radiation. MR imaging has inherently greater soft-tissue contrast than other imaging techniques. When used in conjunction with dynamic scanning

A double-blind comparative study of the nonionic contrast medium iopentol and the ionic contrast medium metrizoate for urography was carried out in 200 adult outpatients. Significantly less discomfort and other side effects were observed following iopentol than following metrizoate. No serious adverse reactions and no clinically significant alterations

Magnetic resonance (MR) urography has become an integral part of the recently emerging advances that involve clinical uroradiology. MR urography has received a relatively lower attention than multidetector CT (MDCT) urography, being hampered by the low spatial resolution which is crucial for calyceal evaluation and by the requirement of updated MR ...
