An NMR zeugmatographic scanner is modified to produce flow images. A motion sensitizing gradient field is applied to the gyromagnetic nuclei after transverse excitation and prior to emission measurement. The motion sensitized free induction signal which results is processed using an inverse Fourier

Diese Dissertation ist auf den Internetseiten der Hochschulbibliothek online verfügbar. Foreword Many people were involved in this interdisciplinary project. They worked together from the beginning until the end. Firstly, they designed and constructed the experimental equipment and secondly, developed measurement techniques and tested them for different geophysical applications. Then the author would like to mention personally Dr. Sophia Anferova, Prof. Vladimir Anferov, and Juliane Arnold for the teamwork. I would like to underline the collaboration with Prof. Christoph Clauser’s group

electronics industry have led to the widespread availability of inexpensive radio-frequency integrated circuits with exceptional abilities. We have developed a small, lowcost MR system derived from these new components. When combined with inexpensive desktop magnets, this type of MR scanner has the promise

secondary to ruptured aneurysm. A third patient, with subcortical arteriosclerotic ence-phalopathy, so-called Binswanger's disease, was examined antemortem using a 0.6 tesla scanner. Nuclear magnetic resonance images were reconstructed at levels matching the pathologic specimens. Qualitative and, when

We describe a 3.35 T DNP/9.4 T MRI installation based on a continuous-flow cryostat, using a standard wide-bore low-field NMR magnet as prepolarizer magnet and a widely available

-FDG were performed in 1925 subjects for evaluation of different, non-thyroid malignancies. For PET/CT examination, a Discovery ST (General Electric) PET/CT scanner was used. Patients with focal 18F-FDG activity were further evaluated by means of fine needle aspiration biopsy (FNAB). If cytological

muscle and fat separately by taking advantage of the difference in the spin–spin relaxation time (T2) between water molecules in muscles and fat molecules, which would contribute to the non-invasive and objective determination of marbling scores. With this in mind, we developed a prototype NMR scanner (4

Measurement of magnetic field distribution of the basic magnet is rather frequent measurement in Nuclear Magnetic Resonance (NMR). It can be useful for maintenance of the NMR scanner as well as for
