    Notes: Summary In a previous study, the authors demonstrated that in 17 men with ischaemic atherosclerotic disease the bone mineral density (BMD) of the femoral neck was lower than in matched control subjects. The patients with arterial disease were thinner and were heavier smokers than the controls. Osteoporosis and arterial disease of the lower limbs were perhaps due to common risk factors: tobacco consumption and a low body build index. In order to demonstrate the direct effect of atherosclerosis on bone mineral content (BMC), the authors studied by dual-energy X-ray absorptiometry the BMC of both legs in 18 men presenting symptomatic arterial disease of the lower limbs quantified by measurement of distal systolic indexes by doppler ultrasonography. The mean BMC of the leg more severely affected by arterial disease was significantly lower than the mean BMC of the leg less affected by arterial disease (512±76 g versus 495±80 g: p=0.003). In 13 of the 18 patients, the BMC was lower in the leg more severely affected by arterial disease; in 4 of 18 the difference between the BMC of the left and right legs was less than 1%, and in a single patient the BMC was higher in the leg more affected by arterial disease. Arterial disease of the lower limbs could lead to bone mineral loss.

    Noninvasive electromagnetic blood flowmeter: Theoretical aspects and technical evaluation (1982)
    Springer
    Medical & biological engineering & computing 20 (1982), S. 671-680 
    Details
    ISSN: 1741-0444
    Keywords: Computerised signal processing ; Electromagnetic method ; Noninvasive blood flow measurement ; Pulsatile blood flow rate

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract A new noninvasive device for measuring pulsatile blood flow is described. This device operates on the same well known principle as the invasive electromagnetic flowmeter. The theoretical aspects are developed from Maxwell's equations to obtain the direct relationship between blood flow rate and measured electrical potentials, which allow calibration in this method. Computerised signal processing is used to purify these potentials from noise and to isolate the pulsatile blood flow signal from physiological artefacts such as the electrocardiogram and ballistocardiogram.In vivo andin vitro experiments have been performed to determine the influences of physical and biological factors on the recorded blood flow curve. Correlation with the invasive electromagnetic device has been established. Application to the measurement of the pulsatile blood flow from human lower limbs is presented.
