The correct answer is LR-5, as it is the only one with a single, definite diagnosis, that of HCC. All the others can be consistent with at least two distinct pathologies.\u003c/p\u003e","id":2189,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/3106","nextQuestionPath":"/articles/li-rads-overview/questions/2074","relatedArticles":[],"alsoUsedIn":[],"stem":"\u003cp\u003eOf the following possible classifications of a liver lesion according to the Liver Imaging Reporting and Data System (LI-RADS), the diagnosis is definite and certain for lesions categorized as...\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2189"}],"attemptsPercentages":[{"alternativeId":"10869","percentage":68},{"alternativeId":"10867","percentage":2},{"alternativeId":"10866","percentage":6},{"alternativeId":"10868","percentage":9},{"alternativeId":"10865","percentage":15}],"promptToLogin":false,"questionManager":false,"articleId":"li-rads-overview"}
