Define a phase image acquisition protocol composed by non-enhanced,
nephrographic and excretory or delayed phases. Develop a system for the interpretation of ureteral anomalies and composing the structured radiological report. Identify ureteral anomalies and provide a specific diagnosis when possible. Describe the characteristics of most common ureteral pathologies on CT-urography.
CT urography is a technique increasingly used for the evaluation of the ureters.
It is often possible to identify incidental findings that draw the attention of the radiologist.
It is essential to differentiate the anatomical variants and other physiological findings from pathological ones.
Findings and procedure details
Image acquisition protocol In our institution,
the CT-urographyprotocol consists on acquisitions in three phases that are sent to the PACS in both transversal plane and coronal reconstruction.
It is carried out according to the following indications: Without-contrast phase. It is used as a basis for later characterization of the contrast uptake of possible lesions. Nephrographic phase. It is acquired approximately 90 seconds after bolus administration.
It allows the study of the renal...
CT-urography is widely accepted as a first-line imaging modality in the study of ureteral pathology.
It is necessary for the radiologist to recognize the wide range of anatomical variants and ureteral diseases,
in order to limit the diagnosis. Uro-CT allows the interpretation of ureteral abnormalities including congenital ureteral abnormalities,
stenosis and deviations of its path. All these findings must be reflected in a structured radiological report that allows...
