    Impedance plethysmography for blood flow measurements in human limbs (1992)
    Springer
    Medical & biological engineering & computing 30 (1992), S. 518-524

    Notizen: Abstract The cross-sectional area of a limb varies along the extremity. This is of great importance when impedance plethysmography is used for limb blood flow studies. The actual measurement site, as well as the interelectrode distance, must be carefully selected to avoid underestimation of the blood flow value. The distance between the potential electrodes should be less than 10 cm for an adult subject.

    Pharmacokinetics of 11C-labelled BCNU and SarCNU in gliomas studied by PET (1991)
    Springer
    Journal of neuro-oncology 10 (1991), S. 47-55 
    Details
    ISSN: 1573-7373

    Thema: Medizin
    Notizen: Summary This paper describes the study of the pharmacodynamics of two 11C-labelled nitrosoureas, 1,3-bis-(2-chloroethyl) nitrosourea (BNCU) and sarcosinamide chloroethylnitrosourea (SarCNU), both labelled in the carbonyl position. Distribution of the radioactivity as measured by positron emission tomography was compared to the distribution of radioactivity observed after injection of 68Ga-EDTA, this being used as an indicator of the blood-brain barrier integrity around the brain tumor. Data suggest that the new nitrosourea, SarCNU, most likely enters brain tissue by different mechanism(s) than BCNU, which enters by diffusion. Data also indicate that use of SarCNU may result in a better tumor to brain ratio than BCNU.
