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.
