| BACKGROUND: Transarterial chemoembolization (TACE) is a widely accepted palliative therapeutic approach for patients with intermediate-stage hepatocellular carcinoma (HCC). AIM OF THE WORK : This work aimed to detect the accuracy of maximum intensity projection (MIP) and volume rendering technique (VRT) techniques in identifying tumor-feeding arteries in patients undergoing TACE of hepatocellular carcinoma. PATIENTS AND METHODS: This is a Retrospective study involved 34 patients with HCC who underwent TACE at the National Liver Institute, Menoufia University, Egypt. All patients underwent triphasic dynamic multidetector computed tomography (MDCT) prior to embolization. Arterial-phase images were reformatted and reconstructed using MIP and VRT techniques for the visualization and identification of tumor-feeding vessels. The findings were compared to digital subtraction angiography (DSA), which served as the reference standard. The diagnostic performance of both imaging techniques was statistically assessed in terms of accuracy. RESULTS Substantial interobserver agreement was noted for both MIP and VRT (κ=0.705 and 0.671, respectively. Detection scores using MIP were elevated than VRT (mean 1.82 and 2.05 for observers 1 and 2, respectively, vs. mean 1.11 and 1.29 for observers 1 and 2, respectively; p < 0.001). The accuracy of MIP and VRT in detecting tumor-feeding vessels, compared to DSA, was 68.89% and 42.22%, respectively. CONCLUSIONS: MDCTA using MIP technique is significantly accurate more than VR technique in the assessment of tumor-feeding arteries . | ||
