Table 5.
Different IC Na MRI signal intensities represent the matched locations of different tumor premalignant and malignant stages on tumor histology sites as shown in Figure 7 in different panels for: pre-malignant features [intraductal proliferation 11.5(2); ductal hyperplacia 8.8 (3); apoptosis with intraductal carcinoma 12.4* (6,13) and active proliferation 6.2* (2); ductal carcinoma 14.2* (17); cribriform ductal carcinoma 12.8* (7); ductal comedo carcinoma 12.2* (4)]; Malignant features [papillary carcinoma 13.5* (9,11); invasive cribriform carcinoma 12.8* (18); invasive comedo carcinoma 13.5*(22); tubular carcinoma 13.8*; adenoma 12.5* (2,8)]. The IC Na concentrations were measured by using IC Na MRI phantom standard graph as shown in Figure 2.
