Answer

Answer

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.
