to evaluate the diagnostic accuracy of the quantitative assessment of multidetector CT perfusion in hepatic metastases.

Material and Methods

This prospective study included 46 patients underwent multi-detector computed tomography perfusion (MDCT-P) with detected hepatic focal lesions by MDCT. They are divided into 2 groups: Group I metastases (36 cases, 10 males and 26 females) of known primary cancer. Group II non-metastases (benign featuring) hepatic focal lesions in 10 patients (one male and 9 female).

Results

In group I (liver metastases the BF show more than double increase in the metastasis (mean: 324.7 mm/min/100g) compared with the BF of background liver (133.9 mm/min/100g) with significant P value (0.029). While MTT show significant decrease in these FL (mean was 6.4 sec.) in the metastases compared with liver which was (13.7 sec) with 0.01 P value. The PS and BV show no …
