The shape of the index correlation function is sensitive to concurrent and future risk of neoplasia in the AOM-treated rat. (a) Comparison of the $m$ values from the copolarized and crosspolarized signals for saline versus all AOM-treated rats shows a statistical significant increase in $m$ ($P$ $\text{value}=0.007$ and 0.003). (b). Comparison of the shape of index correlation function shape between saline and AOM-treated rats. (c). Comparison of $m$ values between saline controls and AOM-treated rats who had and had not developed tumors at the 18-week measurement point. The $m$ value is highest for rats harboring a tumor but is also significant for AOM rats that had not yet developed a tumor. Solid circle points are group means and error bars are 95% CI.
