Abstract Focal liver disease includes wide variety of benign and malignant lesions that represents a common diagnostic problem referred to radiologists for evaluation owing to its nonspecific clinical presentation. Focal hepatic lesions (FHLs) are diagnosed using ultrasonography (USG) and/or computed tomography (CT). Diffusion-weighted magnetic resonance imaging (DW-MRI) is a technique that is able to provide both anatomical and functional details for hepatic focal lesions. Diffusion tensor imaging (DTI) is MRI technique that reveals microstructural characteristics of biological tissue, which can detect the degree of diffusion in multiple dimensions by using addition gradients. The aim of the present study is to evaluate the role of DTI in characterization of previously diagnosed hepatic focal lesions, either benign or malignant and correlate the results with other imaging modalities (Triphasic CT or Dynamic MRI). The study was conducted during the period from January 2018 to January 2020 and included 30 patients (16 men and 14 women; mean age, 51.8 years) who were referred from oncology center and tropical unit with focal hepatic lesions diagnosed with different imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI) and or biopsy. After obtaining a written informed consent, the cases were subjected to full history taking and clinical examination. |
