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 …

Aim

To determine the role of multi-detectors CT perfusion in differentiating hepatocellular carcinoma from hemangiomas.

Material and Methods

This prospective study included 42 patients underwent multi-detectors computed tomography perfusion (MDCT-P) with detected hepatic focal lesions by MDCT. They are divided into 2 groups: Group I Hepatocellular carcinoma (22 cases, 13 males and 9 females). Group IIHemangiomas (20 patients, 2 males and 18 females).

Results

In group I (Hepatocellular carcinoma) the BF show significant increase (near four times)(mean: 281.9 mm/min/100g) compared with the BF of background liver (72.8 mm/min/100g) with significant P value (0.009). While MTT show significant decrease in HCC (mean was 8.7 sec.) in compared with liver which was (21.5 sec) with 0.001 P value. The PS and BV show no significant changes. In group II (Hemangioma) significant reduction in BV …

Purpose

To retrospectively evaluate tumor response, local tumor control, and patient survival after the treatment of pulmonary metastases using transpulmonary chemoembolization (TPCE) in palliative and neoadjuvant intent.

Materials and methods

One hundred forty-three patients (mean age 56.7 ± 13.4 years) underwent repetitive TPCE (mean number of sessions 5.8 ± 2.9) between June 2005 and April 2017 for the treatment of unresectable lung metastases, not responding to systemic chemotherapy. Patients had predominant lung metastases with bilateral lung involvement in 80.4% of the cases. Regional delivery of the chemotherapeutic agents was performed through selective catheterization of the tumor-supplying pulmonary arteries with subsequent injection of iodized oil and microspheres. Patients, who underwent subsequent ablation (n = 51), either for all lesions (complete) or dominant lesions …
