Relaxation Measurement of Ex-Vivo Breast Cancer Tissues at Ultralow Magnetic Fields

Figure 5

The ratio between the tumor (T) and the normal (N) tissue as a function of the cancer ratio. Since the normal tissue in specimen S13-05 was 5% cancerous, the surface ratio of the cancer of this specimen was denoted as 55%. The (red) closed circles, (blue) open circles, and (green) closed squares represent the data obtained at 122, 62, and 37 μT, respectively. The error bars indicate the standard errors. The lines are linear fits to data obtained at each field.
