title: [Duration of the retention of iodine contrast agents in the body--an x-ray fluorescence analytical determination].
abstract: X-ray fluorescence is able to detect iodine as it is used in contrast agents with low concentrations in vivo in man. Measurements of the time dependence of this concentration after angiographies show that one must distinguish between patients with a defect in the blood-brain barrier and those with an angiographically demonstrated arterial flow reduction.
