Comparison of Turbo Flash and dual-energy modes of third-generation dual-source CT in pre-transplant renal angiography: a prospective observational study

Egyptian Journal of Radiology and Nuclear Medicine

Table 2 CT parameters used in two groups

Parameters	Group A	Group B
Tube current (Kvp)	90/Sn 150	120
Tube current time product (mAs)	Care dose	Care dose
Pitch	0.9	2.0
Rotation time in secs	0.5	0.25
Collimation	128 × 0.6	192 × 0.6

Group A underwent renal CTA in a dual-energy mode scanner with a conventional pitch (pitch = 0.9) and 1.0 mL/kg CM injection, with parameters from the standard protocol used in our institution
Group B underwent renal CTA on the same scanner via a Turbo Flash mode (pitch = 2.0) with 0.5 mL/kg CM injection
