Triphasic Computed Tomography Hounsfield and Pattern in Differentiation of Focal Liver Lesions

Objective: To evaluate the diagnostic value of triphasic spiral Computerized Tomography (CT) Hounsfield (HU) and pattern in differentiating focal liver lesions. Methods: The study was conducted in Department of Radiology:1) Fedail Hospital, 2)Alfaisal Hospital,3) Alzitona Hospital,3) Alturky Center.The study was obtained during the period spanned from January 2015up to August 2016.By convenient sampling, 99 patients who were found to have focal liver lesions were recruited and their triphasic CT scans findings were evaluated. Results: Among the 99 cases of patients with liver lesions it was found to be: 21 hemangiomas, 13Cyst, 38 Metastases, 24 Hepatocelluler Carcinoma, 2 Ischemia and abscess were found in 3cases. All were diagnosed using the typical enhancement patterns and quantification method (HU) values. Based on the results, it could be judged that triphasic CT scan has a great value in diagnoses and differentiating focal liver lesions and the underlying causes significantly at p≤0.000. Conclusion: Triphasic CT scan is a good non-invasive tool and can be used as first line imaging modality for differentiating focal liver lesions; therefore unnecessary biopsies can be avoided.
