3. If these exams reveal evidence of UTO but no discernable source, multiphase contrast enhanced CT urography and/or dynamic contrast enhanced MR urography (DCE-MRU) may be performed to delineate a cause. These are often performed in conjunction with direct ureteroscopic evaluation. CT urography: Review of technique and spectrum of diseases.

CT urography protocol included three volumetric acquisitions of the abdomen and pelvis. 2017-02-24 CT Urography facilitates multiplanar imaging of the urinary system, thus is an excellent technique in evaluating the urinary tract calculi and renal is essentially defined as a CT examination of the urinary tract which includes non-contrast or unenhanced phase imaging 2013-10-02 Improved CT SPR processing technology produces radiographlike images, thus eliminating patient transportation between the CT and urography suites or the necessity for a CT suite with a ceiling-mounted x-ray tube and a modified CT tabletop for performance of EU. CT urography results in a higher radiation exposure than excretory urography [13, 33]. The effective dose of CT urography protocol in our study (approximately 20 mSv) was 2.5 times that of excretory urography (7.9 mSv). The three-phase CT urography dose in this study is comparable to previously reported values (14.8–22.6 mSv) [13, 33].

Wang et al. [46] found that approximately two-thirds of tumors smaller than 1 cm were undetectable on CT urography. In order to do this, several measures may be taken to minimize the amount of unopacified urine in the bladder. Patients can be asked to void completely prior to CT urography. Alternatively, patients can be asked to roll over on the CT table several times and/or to ambulate just prior to excretory phase image acquisition. 1.

As such, CT urography and MRI have shown remarkable improvement in the detection of bladder TCC. However, the most important limitation of CT and MRI is that they have limited ability in detecting small (<1 cm) or flat tumors [28,46]. Wang et al. [46] found that approximately two-thirds of tumors smaller than 1 cm were undetectable on CT urography. CT Urography for Evaluation of the Ureter. Over the past decade, computed tomographic (CT) urography has emerged as the primary imaging modality for evaluating the urinary tract in various clinical settings, including the initial workup of hematuria. With the widespread implementation of CT urography, it is critical for radiologists to under …. CT urogram.
