What are any side effects from an MRCP test?

This is an MRI of the liver bladder and upper gut area. Then we use software to reconstruct the images and the final product would resemble a scope / camera was put into the bile duct and hepatic duct to see if there is an obstruction and why. It is safer and more comfortable than the traditional test when we put in a real camera through the mouth to the stomacn then to the bile duct (called ERCP). Don't worry.
