Characterization of Liver Lesions using Tri Phase Multi Detector Computed Tomography

Abstract

The advent of computed tomography (CT) has considerably facilitatedthe diagnosis of lesions of the liver, The objective of this study was To characterize liver lesions in triphasic spiral computerized tomography and To evaluate the diagnostic value of triphasic spiral Computerized Tomography (CT) Hounsfield (HU) and pattern in differentiating focal liver lesions.The study was conducted in Department of RadiologyFedail Hospital, Alfaisal Hospital, Alzitona Hospital, AlturkyCenter.The study was obtained during the period spanned from January 2014up to December 2016.This study 138 patients with liver disease underwent triphasic liver (CT) 64 male 74 female . After injection of contrast material, the liver was scanned in arterial, portal and delay phases Triphasic liver CT enables to characterize a wide range of hepatic infiltration, focal liver lesions, including the benign and malignant lesions as well as metastases that occur most frequently.Triphasic CT scan is an acknowledged non-invasive imaging technique and can be used as first line imaging modality for differentiating focal liver lesions using this quantification method and its homogeneity in all of the scanning phases. Benign lesions like haemangioma can be reliably differentiated from malignant liver lesion using the texture and HU values .It is also particularly supportive for hyper vascular lesions which can be easily overlooked on routine CT scanning; therefore unnecessary biopsies can be avoided.
