N.m.r. relaxation and images of human breast tumours in vitro.
It is found that fat and non-fatty tissue in dissected samples of the mamma differ in their T1/T2 ratios. This opens the possibility of locating tumours by n.m.r. imaging, because they have a lower fat content than their surroundings. By means of a sensitive point method, samples were scanned with a resolution of about 0.4 mm X 0.4 mm. The similarity between the shape of a tumour in an n.m.r. and in an X-ray image of a thin section of mamma tissue is quite convincing.
