Table 2 CT parameters used in two groups

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

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
  1. 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
  2. Group B underwent renal CTA on the same scanner via a Turbo Flash mode (pitch = 2.0) with 0.5 mL/kg CM injection
