Note that this coronal section is angled forward so that it is at a right angle to the long axis of the hippocampi (this is a TLE protocol) and is passing through the tectal plate and thus posterior part of the third ventricle. The internal cerebral veins will then join together in the quadrigeminal cistern.\u0026nbsp;\u003c/p\u003e","id":682,"imageUrl":"https://prod-images-static.radiopaedia.org/multiple_choice_questions/791/images-for-mcqs-1__1__big_gallery.jpeg","imageAttribution":{"kind":"case","rID":40748},"imageAttributionCaseInfo":{"title":"Normal brain MRI (TLE protocol)","contributor_name":"Frank Gaillard","contributor_param":"frank","case_rid":40748,"case_param":"normal-brain-mri-tle-protocol"},"firstQuestionPath":"/questions/682","nextQuestionPath":"/articles/ventricular-system/questions/681","relatedArticles":[{"id":5780,"title":"Third ventricle","link":"/articles/third-ventricle?lang=us"}],"alsoUsedIn":[],"stem":"\u003cp\u003eIn the accompanying coronal T2 MRI of the brain, the third ventricle is indicated by which letter?\u0026nbsp;\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/682"}],"attemptsPercentages":[{"alternativeId":"3429","percentage":6},{"alternativeId":"3432","percentage":2},{"alternativeId":"3430","percentage":81},{"alternativeId":"3431","percentage":9},{"alternativeId":"3428","percentage":0},{"alternativeId":"3427","percentage":2}],"promptToLogin":false,"questionManager":false,"articleId":"ventricular-system"}
