MRI Renal Angio Protocol

Normal MRA-RENAL ANGIO Protocol


  • Coronal 2D steady-state precession sequence was performed for localization of the origin of the renal arteries
  • Pre-contrast Coronal-3D GRE (Mask)-Coronal breath-hold fat-saturated spoiled gradient-recalled echo sequences (fast low-angle shot)
  • Post-contrast Coronal 3D GRE + 3D RECONS
Optional
  • Coronal 2D FIESTA FS / BALANCED FFE / TrueFISP
  • Axial T2 SSFSE / SS TSE / HASTE
  • Axial 2D FIESTA FS /BALANCED FFE / TrueFISP
  • Axial GRE IN/OUT PHASE

TECHNICAL NOTES
  • Contrast administration dose-0.2 mmol/kg for 1.5 T and at a dose of 0.1 mmol/kg for 3 T
  • The sequence was immediately started when bolus tracking showed contrast agent in the abdominal aorta. 
  • The injection rate was kept constant to keep the bolus as compact as possible.
