Abstract

Background & Methods: The aim of the study is to assess the role of DCE-MRI in characterizing the liver lesions into the various types. The patient was then placed on the gantry table in supine position with arms placed above the head. Patient was explained to hold his/her breath on verbal instruction and to resume breathing on reinstruction. In case patient was dyspneic or was unable to hold breath for reasonably long time, he/she was advised to maintain shallow breathing. Results: The most common age group among our study was between 40-49 years. Pain was the most common presenting complaint, and 36 % patients had a previous history of malignancy. 50 lesions were diagnosed as benign on MRI, while 44 being malignant. Peripheral nodular enhancement with delayed filling in was the most common enhancement characteristic seen in Hemangiomas, while rapid arterial phase enhancement with rapid washout was most commonly seen in HCC's, heterogeneous enhancement was most common for metastatic lesions Conclusion: Liver lesions are very common, ranging from benign solitary lesion to multiple liver metastases. Histopathological examination makes the definitive diagnosis but DCE-MRI is highly effective tool in making the diagnosis non-invasively and help in planning the treatment of patient. It helps in differentiating between pseudo tumors lesions like focal fatty infiltration, infection (abscess, hydatid cyst etc.) & inflammatory disorders of liver and tumors. It can characterize tumors into benign and malignant lesions and can be also utilized for differential diagnosis in complicated cases.
