At our institution, patients are instructed to avoid caffeine and smoking 12 hours prior to the procedure to avoid cardiac stimulation. They are also instructed to avoid eating solid food 4 hours before the study and to increase fluid intake prior to the study. Standard precautions with regard to contrast allergy history and renal function are taken.
