Evaluation of different parameters contrast media enhancement for the differentiation between scar tissue and local recurrence rectal cancer.We included 83 patients after operation radiotherapy cancer. In total, 20 recurrences were diagnosed. After administration 75 ml Iopromide (370 mg/ml) a delay 65 s, whole abdomen pelvis scanned in collimation 4 x 2.5 mm 12.5 table feed per rotation. The suspected was marked by freehand ROI option every slice minimum, average maximum densities calculated. A if density higher than 90 HU admission media. addition we calculated difference as minimum density.The showed no reliable differences with or without (minimum ( +/- 12 HU) vs. 13 21 HU), P = 0.23, 48 10 17 HU)), 0.52. suffering from (maximum 111 81 24 0.02, 103 76 31 0.06.
