Steering the beam through the liver causes less sound to be attenuated before reaching the kidney, resulting in a better image. Steering the ultrasound beam through the rib and the colon would be disadvantageous since both have a high acoustical impedance and causes\u0026nbsp;“acoustic shadowing.” The right adrenal gland is too small to act as a meaningful acoustic window.\u003c/p\u003e","id":2399,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2399","nextQuestionPath":"/articles/adrenal-gland/questions/660","relatedArticles":[{"id":1566,"title":"Large intestine","link":"/articles/large-intestine-1?lang=us"},{"id":25813,"title":"Kidneys","link":"/articles/kidneys?lang=us"}],"alsoUsedIn":[{"id":1355,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1355","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1355"},{"id":1200,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1200","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1200"},{"id":248,"kind":"LiveSchedule","title":"248","link":"https://radiopaedia.org/admin/live_schedules/248"},{"id":169,"kind":"LiveSchedule","title":"169","link":"https://radiopaedia.org/admin/live_schedules/169"},{"id":1315,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1315","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1315"},{"id":1315,"kind":"Course","title":"X-ray \u0026 Ultrasound Lectures - page 1315","link":"https://radiopaedia.org/courses/xray-lectures/pages/1315"}],"stem":"\u003cp\u003eTo better see the right kidney, it is useful to image the kidney through which structure?\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/2399"}],"attemptsPercentages":[{"alternativeId":"11817","percentage":1},{"alternativeId":"11816","percentage":81},{"alternativeId":"11818","percentage":2},{"alternativeId":"11815","percentage":16}],"promptToLogin":false,"questionManager":false,"articleId":"adrenal-gland"}
