To demonstrate the tissue differentiation potential of MR (magnetic resonance) imaging studies, preliminary data were acquired on the distribution of proton spin-spin relaxation time, T2, in normal and malignant tissues in twenty patients with head and neck tumors. Malignant tissue generally has longer proton relaxation times than found in normal tissues. The T2 distributions within neck and neck tumors were both elevated and broader than found in normal issues. The regional distribution of the T2 values indicated that the maximum T2 values are near the tumor center and decreased in the MRI slices at the tumor periphery. It is concluded that the T2 distribution provides information for delineating the extent of abnormal tissue even without a complete understanding of the mechanism(s) leading to the elevated and broad T2 distribution within the tumor bed.
