Abstract

For decades, traditional IVU studies have been the mainstay in the investigation of urinary tract calculi and obstruction. However, they have been largely superseded by non-contrast CT in the present day. The use of contrast material further expands the utility of CT in the evaluation of urinary tract disease, allowing detection and characterization of renal masses and urothelial lesions. In this review article, we discuss the development and current role of CT urography as the complete imaging investigation in the genitourinary system. Conventional multiphasic protocols and split-bolus techniques for radiation dose reduction are considered. We then focus on how recent technological advances have allowed dual-energy CT to play a complementary role in CT evaluation of the genitourinary system, allowing stone and renal mass characterization, as well as creation of virtual unenhanced datasets. The use of associated post-processing software applications in the clinical context is illustrated.

In this review article, the high diagnostic accuracy of CT urography for urothelial cell carcinoma is highlighted. In patients with hematuria and at high-risk for urothelial cell carcinoma, CT urography is recommended as the initial imaging investigation and as a triage test for cystoscopy. This allows earlier diagnosis and better prognosis.

This prospective study of 30 patients with either haematuria or diagnosis of urothelial cancer (confirmed or suspected) showed that dual-energy split-bolus CT urography is technically feasible. Quality of dual-energy combined nephrographic-excretory phase images was found to be satisfactory. Omission of true non-enhanced images can reduce total radiation dose by 52 %, but quality of virtual non-enhanced images is not optimal and true non-enhanced images are still required when urine attenuation values need to be measured.

Abdom Imaging. 2013;38:1136–43. doi:10.1007/s00261-013-9992-9. This prospective study of 100 patients with urinary stones (as seen on true non-enhanced images) showed that split-bolus dual-energy CT urography was technically feasible, with better quality of virtual non-enhanced images (lower image noise and improved iodine subtraction) on 100/140 kVp setting compared to 80/140 kVp setting, both settings utilising tin filtration. On virtual non-enhanced images, 17 % of stones were missed and these missed stones were statistically significantly smaller than stones correctly found. The authors concluded that on virtual non-enhanced images, detection of urinary stones <4 mm was limited.

This review article provides an overview of dual-energy CT applications in the characterisation of renal lesions. Due to the increasing numbers of multidetector CT studies performed, the number of incidental renal lesions has increased, a significant number of which are indeterminate and require further evaluation. Dual-energy CT, as a material-specific spectral imaging investigation, is able to circumvent some of the technical limitations of conventional monoenergetic CT, improving diagnosis of renal lesions and preventing unnecessary further investigations.
