Single dose oral cholecystography.

The routine use of single dose oral cholecystography is suggested for the examination of outpatients. A diagnosis is more quickly obtained for the great majority of patients and there is a lower incidence of side effects. An effective method of contrast administration and filming is discussed. The medical, personal, and economic impact of single dose oral cholecystography is contrasted with that for routine consecutive dose examinations in an outpatient population.
