Background: Tumor pathologies of the liver and bile ducts are relatively\ncommonly diagnosed and the primary goal is to differentiate these lesions in\nthe fastest possible time which determines the apropriate method of treatment.\nAims and Objectives: Aim of this study is tracking and diagnostic imaging\ncorrelation of tumor pathologies of liver and bile ducts and determining the\nearly diagnostic approach. Data obtained from this study are important for\ntreatment procedures and succes of treatment. All cases with liver tumor\npathologies from period 2012-2016 were examined with CT and MRI followed\nby other complementary imaging methods. Methods: CT examination was\nperformed according to standard triple-phase protocol: non-enhanced phase,\narterial phase and porto-venous phase, and in some cases with late phase after\n5 minutes. In MRI examinations, standard protocol was performed: coronal\nT2 single-shot fast spin-echo (coronal T2 SSFs), Axial T2 respiratory-triggered\nfast spin-echo (axial T2-FRE)/or breath-hold fast-recovery fast spin-echo T2\nbody coil sizes XL, (axial T2-FRFSE-XL), Axial in-phase/out-of-phase, Axial/\ncoronal three-dimensional liver acquisition with volume acceleration (3D\ncoronal pre lava). Results: For comparation, only patients with liver focal\nlesions were included in the study, and and patient were examined with both\ndiagnostic imaging modalities (CT and MRI). 168 patients with liver tumor\npathologies and biliary tree tumor pathologies are included in the study.\nGender ratio was 85 males and 83 female (M/F ratio 1.03:1). Average age of\npatients was 58.41 years, (minimum age 1.5 years old and maximum 88 years\nof age). The most frequent age on diagnosis was 61 - 70 years (total of 49\npatients or 29.16%). Benign tumors were found with 93 patients (55.35%) and\nmalignant tumors in 79 patients (47.02%). Distribution in liver parenchyma was found in 113 patients (67.26%), while in 49 patients (29.17%) pathology\nwas found in the biliary tract. The most affected liver segment was the fifth\nsegment in 35 patients (20.83%), while the less affected segment was the\nsecond liver segment in 8 patients (4.73%). most of patients (62 patients or\n36.90%) had more than two affected segments in time of diagnosis. Diagnostic\ncriteria in this study require further future evaluation. Conclusion: Early\ndiagnosis of are tumors remains a real challenge and has great impact in the\nsurvival rate of patients. Finally, our study showed that for our country�s\ninstitutions that there was no significant difference between both CT and MRI\nmodalities in liver focal lesions assessment.
