NMR in cancer: XVI. FONAR image of the live human body.

The FONAR technique that achieved the first chemical image of the live human being is described. Color and black-and-white video images of a cross-section through the chest at the level of the eighth thoracic vertebra were generated. The imaging showed the heart and mediastinum in the midline between the left and right lungs with the heart encroaching on the left lung space as it does at this level. Also seen was the descending aorta just left and anterior to the vertebral body.
