Scan Delay (sec)25 sec arterial / 60 sec venous / 240 sec excretory phase
3D Technique UsedVRT w/ MIP
Comment: - Depending on the case and what is seen on the arterial phase, a venous phase can also be obtained similar to protocol for the renal mass. A key for hematuria is to exclude a uroendothelial tumor and delayed scans at a minimum of 4 minutes are needed. We routinely will do a CT urogram at the 4 minute mark. We reconstructed the data using a variety of opacities of VRT.
