Nuclear magnetic resonance studies of several experimental and human malignant tumors.

Abstract

Summary Several animal and human malignant tumors were examined by nuclear magnetic resonance spectrometry. When compared with normal tissue, the spin-lattice ( T 1 ) magnetic relaxation times were longer for all tumors except one human sample. Comparable results were obtained for T 1 measurements of cultured tumor cells. Possible mechanisms for this effect are reviewed briefly and its potential in cancer diagnosis is discussed.
