Nuclear magnetic resonance imaging of human lymph nodes.
MR-imaging of surgically excised enlarged and non-enlarged human lymph nodes was studied in patients with and without malignant metastatic lymphadenopathy. NMR tomograms were performed at frequency of 200 MHz using the CPMG sequence. Space resolution was up to 0.1 mm. "In vitro" NMR-tomograms of both non-enlarged and enlarged lymph nodes disclosed tiny foci of metastatic deposits. It is proposed that use of T2 differences for localization of a pathologic focus is an effective mode of visualization during NMR tomography at high frequency.
