    Analysis of trabecular bone structure in the distal radius using high-resolution MRI (1994)

    Notes: Abstract The objective of this study was to develop high-resolution in vivo Magnetic resonance techniques to resolve the structure of trabecular bone in conjunction with image processing techniques to quantify variations in trabecular bone structure. Such techniques could then potentially be applied to assess osteoporotic changes and predict the risk fractures. Axial and coronal volumetric MRI images of the distal radius were obtained using a modified gradient echo sequence on a MRI images, on a 1.5 T imager at a spatial resolution of 150 μm and a slice thickness of 0.7 mm. Image thresholding techniques were used to identify trabecular bone and bone marrow: thereafter the area occupied by trabecular bone, mean trabecular width and mean intercept length as a function of angle were computed. An automatic boundary tracking algorithm was used to identify the bone and marrow interface. Fractal analysis was used to quantify the convolutedness of the marrow-trabecular bone interface. It is well known that the trabecular bone density is the greater at distal sites of the radius and decreases proximally. These variations were reflected by the decreases in the trabecular width. fractional area and fractal dimension. Over a 28 mm range, starting at 7 mm proximal from the joint line and extending 35 mm proximal to the joint line, the mean trabecular width decreased from 444.6 μm to 341.0, μm the fractional area of trabecular bone decreased from 0.44 to 0.15. and the fractal dimension decreased from 1.67 to 1.10. The choice of the threshold affected the quantification of the mean trabecular width and fractional trabecular bone area measurements, but the fractal dimension was more robust. High-resolution MRI images combined with image analysis techniques can he used to quantify structural variations in trabecular bone in the distal radius.

    Imaging of trabecular bone structure in osteoporosis (1999)
    Springer
    European radiology 9 (1999), S. 1781-1788

    ISSN: 1432-1084

    Notes: Abstract. Osteoporosis is a metabolic bone disorder that is characterized by reduced bone mass and a deterioration of bone structure which results in an increased fracture risk. Since the disease is preventable, diagnostic techniques are of major importance. Standard techniques determine bone mineral density, whereas some of the newer techniques focus on trabecular structure. This article reviews structure analysis techniques in the diagnosis of osteoporosis. Imaging techniques applied to the assessment of trabecular bone structure include conventional radiography, magnification radiography, high-resolution CT (HRCT) and high-resolution MR imaging (HRMRI). The best results were obtained using high-resolution tomographic techniques. The highest spatial resolutions in vivo were achieved using HRMRI. The most common texture analysis techniques that have been used are morphological parameters (analogous to bone histomorphometry). Fractal dimension, co-occurrence matrices, mathematical filter techniques and autocorrelation functions are more complex techniques. Most of the studies evaluating structure analysis show that texture parameters and bone mineral density both predict bone strength and osteoporotic fractures, and that combining both techniques yields the best results in the diagnosis of osteoporosis.

    Chlormethiazole and utilization of vitamin B1 in chronic alcoholics (1980)
    Springer

    Notes: Summary Blood vitamin B1 status as reflected by erythrocyte transketolase activation tests has been assessed in 12 chronic alcoholics (M=8; F=4; mean age ±53.4±12.9) both before and after treatment with chlormethiazole and parenteral polyvitamins including thiamine hydrochloride. 7 out of 12 patients (58.3%) were found to be deficient before treatment but all returned to normal after treatment. Mean ± SD, of α ETK improved from the pre-treatment level of 1.174±0.135 to 1.009±0.009 after treatment with thiamine. Chlormethiazole did not seem to interfere with the utilization of thiamine. It is therefore concluded, that though structurally related to the thiazole nucleus of thiamine, chlormethiazole, like thiamine antagonists, does not antagonize the effect of the co-enzyme — thiamine pyrophosphate at the receptor sites on the apo-enzyme — transketolase.

    Notes: Ferromagnetic shape memory alloy of nominal composition Ni50Mn35Sn15 has beeninvestigated by magnetic and transport measurements. Clear signature of first order martensitictransition is observed over a region around 180 K in resistivity, dc magnetization and acsusceptibility data. Field-cooled and zero-field-cooled magnetizations diverge below the martensitictransition, signifying magneto-thermal irreversibility originating from pinning by variants. Thesample shows large negative magneto-resistance (-25% at 90 kOe) in the region of martensitictransition, which was found to be highly irreversible. A clear correspondence between magnetoresistanceand dc magnetization is observed above the field of technical saturation
