Because of the large number and variety of diagnostic examinations available, there are a number of different preparations to be followed, according to the procedure type. To ensure the successful completion of an examination and to maximize diagnostic quality, we ask that patients follow the preparatory procedures carefully and as instructed by the facility where your exam is scheduled.
