To understand the mechanical properties of arteries and vascular grafts, it is crucial that the wall thickness in these vessels be known. Unfortunately, all availble methods for measuring this parameter require the removal of the vessel, which precludes the study of such vessels as a function of time. A new radiographic technique for measuring the wall thickness of arteries and vascular grafts in vivo, utilizing contrast materials injected into the vessel lumen and applied to the outer surface of the vessel, is described. Radiographs are obtained with a portable X-ray machine and analyzed using a calibrated microscope. The technique has been successfully applied to the in vivo measurement of wall thickness in canine arteries, veins, and experimental vascular grafts. It is concluded that the method provides better than 95% accuracy in a variety of vessels and that it can be used to study changes in vascular grafts after their implantation into the arterial circulation.

Environmental lead exposure continues to be a health hazard, especially to young children, and is a serious problem In the U.S. Since lead is stored in the skeleton, measurement of lead in bone (e.g. finger or tibia) can serve as an Indicator of lifetime exposure. Energy-dispersive x-ray fluorescence (XRF) currently seems to be the method of choice for non-Invasive testing, and is expected to be further developed for screening purposes.
