Ease of Use

Topics found in this section are accessed through a bulleted list of "X-rays," "CT scans," "Nuclear medicine scans," "MRI scans," and "Ultrasounds." Each topic links to an individual page on the site. A brief summary is followed by the many links provided for each diagnostic imaging procedure. The deeper you dive into the individual pages, the more time you spend on sites other than MedlinePlus. Users will have to spend significant time reading in order to take in the information from many different links.

Visual Design

Though visually simple, when a page contains over forty different links to outside sources, reading can become overwhelming. Few images populate the pages here, but the topics explored often have links to multimedia, especially videos.


Users will find links to many sources about the five most common types of diagnostic imaging. Diagnostic procedure information is very limited. Inconsistent referencing make the reliability of each MedlinePlus page variable. Topics found in the medical encyclopedia are well referenced, while this is inconsistent for summaries of individual imaging test and information from linked sites. However, most links go to respected federal or specialty organization sites.


MedlinePlus clearly identifies the organizations responsible for the content, which include the American College of Radiology, National Institute of Biomedical Imaging & Bioengineering, American Society of Radiologic Technologists, articles in professional journals, and many government websites. Users will find that the medical encyclopedia topics have the highest reliability by listing reviewers and date of last review. Although MedlinePlus does a great job updating it's pages regularly, the currency of linked sites varies, and individual authors/editors of each topic page are not identified & only occasionally credited on the linked sites.
