1. To understand the particularities of CT and MR imaging techniques in liver cirrhosis. 2. To consolidate knowledge of CT and MR imaging appearance of regenerative nodules, dysplastic nodules, and hepatocarcinoma in cirrhosis. 3. To become familiar with the differential diagnosis in liver cirrhotic focal lesions considering the various enhancement patterns. 4. To discuss the importance of clinical, biochemical information and follow-up of small nodules by the same imaging modality that may be helpful in differential diagnosis of these lesions. This case-based lecture will present typical clinical cases of pelvic pain as well as some unusual but important causes. Cases of acute and of chronic pelvic pain and benign, as well as malignant disease will be included. The audience will have the opportunity to participate in case discussion by the use of interactive voting pads. The selection of imaging modality for each clinical presentation and the importance of knowing the clinical findings at the time of the radiological interpretation will be discussed. For each case, the key radiological features will be illustrated. The essential elements of the radiology report and the key information required by the clinician will be discussed. In each case, the differential diagnosis and the need for follow-up imaging will be considered. The key teaching points for each diagnosis will be reviewed. Learning Objectives:
