Medical imaging by NMR.
Application of the new nuclear magnetic resonance (NMR) method of fast scan proton imaging is described. Cross sectional proton scans of a human finger in vivo are measured and reveal considerable anatomical detail, particularly of the soft tissue regions. Imaging of tumour tissue is also briefly discussed.
متن کاملNmr Imaging New Strategies: Magic Angle Imaging
Until now, the major part of NMR Imaging studies were finalized to diagnostic goals. Hence the main subject of imaging works were the water mobile molecules of biological tissues. Other fields of recent interest were the ima ging of nuclei different from protons and high spatial resolution (NMR microscopy). Another branch of great intere st is the imaging of the broad band components of biologi...
متن کاملNMR imaging of the spine.
The usefulness of nuclear magnetic resonance (NMR) images in the evaluation of spinal disorders below the craniocervical junction was studied. Six normal subjects and 41 patients with various spinal abnormalities were examined. NMR proved capable of demonstrating important normal and pathologic anatomic structures; it was useful in the evaluation of syringohydromyelia and cystic spinal cord tum...
متن کاملNMR Imaging of the honeybee brain
NMR microscopy provides non-invasively distinct soft-tissue contrast in small biological samples. We were able to visualize the three-dimensional structure of the honeybee brain in its natural shape in the intact head capsule. Thus, in addition to acquiring detailed information about the shapes and volumes of the different brain compartments, we were able to show their relative orientations tow...
متن کامل"Shim pulses" for NMR spectroscopy and imaging.
A way to use adiabatic radiofrequency pulses and modulated magnetic-field gradient pulses, together constituting a "shim pulse," for NMR spectroscopy and imaging is demonstrated. These pulses capitalize on phase shifts derived from probe gradient coils to compensate for nonlinear intrinsic main magnetic field homogeneity for spectroscopy, as well as for deviations from linear gradients for imag...
