Abdomen2
  • CT Urography (CTU) has emerged as the modality of choice in imaging of the abdomen in patients with urinary tract diseases due to its high sensitivity and specificity [ 1 ]. (biomedcentral.com)
  • Contrast-enhanced computerized tomography (CECT) abdomen with urography suggested right side crossed fused ectopic kidneys with a solitary ureter draining both kidneys and opening into the left side of the urinary bladder along with a simple cyst of 8 × 7 cm at the upper pole of the right kidney and 3 mm right renal calculus (Figs. 2 , 3 and 4 ). (springeropen.com)
Ureteral2
  • Other clinical situations in which computed tomographic urography may be useful include trauma with suspected ureteral injury, as well as recurrent and/or complex urinary infections to exclude an underlying obstructive etiology or formation of an abscess. (medscape.com)
  • [ 7 ] Note that MR urography is relatively insensitive for the detection of renal and ureteral calculi when compared to CT scanning. (medscape.com)
Urinary tract1
  • Multidetector CT urography: comparison of two different scanning protocols for improved visualization of the urinary tract. (umassmed.edu)

Image1
  • Although modern imaging techniques such as color Doppler sonography, helical or multidetector-row CT, and MRI have substantially improved the potential to image Wilms tumors, definitive diagnosis is still based on histology. (medscape.com)
Excretory urography3
  • Excretory urography (EU) historically was the most frequently performed imaging modality for uroradiology. (medscape.com)
  • The first approach combines axial CT with timed excretory urography (EU) performed by using conventional radiography, digital radiography, or CT scanned projection radiography (SPR). (qxmd.com)
  • Observed defects in general hemostatic tests are prolonged excretory urography for diagnosing transitional cell carcinoma of DBP and 25-hydroxy (OH) in adults with hematuria. (sloggerblog.com)
