Case Discussion

The split bolus technique is employed in investigation of the genitourinary tract.  It is an attempt to maximise the identification of pathology, whilst limiting dose.

Given that one of the key indications is haematuria and the commonality of urolithiasis, is may often be combined with a separate CT-KUB.

The spilt bolus technique images attempts to offer one exposure for the 3 contrast enhanced parts of the so called four-phase CT study (non contrast, corticomedullary, nephrographic and excretory phases).

The excretory phase is synonymous with a CT-IVU.
