we have demonstrated the effect of iodine concentration and radiation quality on this dose enhancement in lymphocytes , we have calculated the effect of such enhancement on depth dose distributions in the brain , we have estimated the iodine content in two human brain tumors during computerized tomography ( ct ) scans , we have studied the dispersion of the iodine contrast media after direct injection into rabbit tumors , and we have demonstrated that the combination of x-ray and contrast media injection is far more effective than either agent alone in causing the regression of mouse tumors .
