Lead concentrations (pglg wet weight) in human bone (tibia) were measured noninvasively in vivo employing an X-ray fluorescence technique. Forty-five workers who had been subjected to chronic industrial exposure were found to have a mean bone lead content of 52.9 pglg wet weight (0 to 198 pglg). In

## Abstract A polarization transfer enhanced inversion‐recovery experiment is proposed for the combined measurement of heteronuclear __T__~1~ and NOE of low‐γ nuclei. This method offers significant time savings compared with conventional relaxation measurements. The reliability and accuracy of the
A 1D MR sequence has been developed for determining aortic flow wave velocity (WV), a metric of arterial compliance, within a single cardiac cycle. Studies were carried out on the thoracic aortas of 10 normal volunteers. Correlative WV data were also acquired from each subject using a conventional p
A method for estimation of 14CO2 present in blood and tissular samples is described. It is basically based on the introduction of large amounts of a gas mixture (95% O2, 5% CO2) in the samples which serves to remove the CO2 label by gas dilution. The gas phase is later captured in scintillation vial
A new simple method for the in situ measurement of the surface transfer impedance of coaxial cables i s described. The method is based on injecting a disturbing current onto the outside of the test cable and measuring the corresponding uoltage induced on the center conductor. It is shown to produce
## Abstract A technique for obtaining T~1~ values from well localized regions using surface coils and with a clinically practicable measurement time is described. The method uses a two‐point Inversion‐Recovery/Saturation‐Recovery (IR/SR) sequence in conjunction with the image‐selected __in vivo__ s
