in periods with extremely high blood pressure that may lead to life-threatening
conditions (hypertensive crisis).
• in situations of highly elevated levels of calcium in the blood
• in delineation of the kidneys and the urinary tract system (urography) for an
enhanced display of the used methods, e.g. contrast medium
