European Radiology - To determine the sensitivity of dual-energy (DE) virtual non-contrast computed tomography (vNCT), generated from the excretory phase of a CT urogram, compared to true...McCoombe, KatherineDobeli, KarenMeikle, Steven
Of 5400 CT urograms performed, 375 (6.9%) in 359 patients aged 40 years or younger with hematuria were included in the study. Urographic findings were tabulated according to their clinical significance. CT images were reviewed to see whether contrast-enhanced images were necessary for diagnosis....
Both the Coronal and Axial cuts were selected from both contrast and non-contrast studies with protocol for the whole abdomen and urogram. The Dicom study was then carefully selected, one diagnosis at a time, and from those we created a batch of Dicom images of the region of interest for ...
In a 71-year-old Japanese male, a left renal tumor was incidentally suspected on excretory urogram. Then CT demonstrated a homogeneous mass in the upper part of the left kidney, 6 cm in diameter, which showed a positive attenuation coefficient, slightly denser than renal parenchyma. Selective ...
While performing a split-bolus CTU, in which way do you divide the whole amount of intravenous contrast medium? * URs (35/73): 34.3% split in half between the two injections; 60% 2/3 during first injection, 1/3 during second injection; 5.7% other (1/3 during first injection, 2/3 ...

Technologic advances in computed tomography (CT) have resulted in the ability to image the urinary tract in ways that surpass the prior main stay of urinary tract imaging, the intravenous urogram Aim of the Study: To assess the role of low dose contrast enhanced computed tomography urography (...
All significant findings that required contrast-enhanced images for diagnosis occurred in patients with predisposing medical conditions. CONCLUSION. A clinically significant source of hematuria was detected in 22.1% of CT urograms of young adults. However, an unenhanced CT alone may be sufficient in ...
Multiplanar and three-dimensional (3D) maximum-intensity-projection (MIP), shaded-surface-display (SSD), and volume-rendered reformatted images of the graft vessels and the recipient iliac arterial system and CT urograms are usually obtained in all cases. All examinations are usually performed befo...
