“Human Anatomy--Dartmouth Medical School” is a site dedicated to radiology. The site contains five tutorials on radiographs (X-ray), magnetic resonance imaging (MRI), computed tomography (CT), fluoroscopy and angiography, and ultrasonography. The site contains a series of learning modules based on a regional approach to human anatomy with an emphasis on radiological images and self assessment of same. Each tutorial consists of four to five learning sections which cover topics such as “How images are obtained,” “Factors affecting appearance,” “What anatomical structures are well seen,” “Indications for use,” and “New technology.” The second part of the site is interactive with further examples of X-rays and MRIs for each region of the body. The “Back,” “Upper Extremity,” “Thorax,” “Abdomen,” “Pelvis and Perineum,” “Lower Extremity,” and “Head and Neck” are included. Within each of these sections is further information on how to read the image and contains several quizzes and practice questions. Also in this section are cadaver images of the “Visible man,” courtesy of the National Library of Medicine for comparison of anatomic structures and structures found in the MRIs or X-rays.
Type of Material:
This site primarily contains tutorials with quizzes, such as self assessment quizes. Sill images, videos, and interactive drag and drop features are included.
Recommended Uses:
This site could be used in conjunction with a structured anatomy and/or radiology class, or as a stand-alone self-study module. The quizzes and practice questions could be used for review to aid students in determining weak areas where more study is needed. The material can be used as a supplement which addresses the need for students to understand radiological and cross sectional images since that is how they will view anatomical structures post basic science training.
Technical Requirements:
The recommended browser is Firefox, although Internet Explorer also worked well. Quick Time™ is needed for the videos.
Identify Major Learning Goals:
Intuitively, a user would use their own course objectives to view and review radiological material as a supplement to anatomy atlases and cadaver study. The primary objective for this material is to introduce basic principles of radiology and to develop an understanding of what you are looking at. Goals of the modules are to: 1) determine how the image is obtained, 2) aAssess factors that affect the appearance, 3) determine what anatomic structures are seen well, and 4) determine what are the indications for use.
Target Student Population:
Advanced upper level undergraduate students and graduate and professional students, such as medical, dental and allied health students. The learning material can be used by medical students and as a review process for the USMLE step one.
Prerequisite Knowledge or Skills:
Some knowledge of human anatomy is needed to fully understand the materials presented. Users who have taken a medical gross anatomy course will benefit most from this site.
Content Quality
Rating:
Strengths:
Material provides a complete understanding of basic principles for radiology
Excellent images! and well-well integrated
An excellent radiological supplement to any gross anatomy course
Material is accurate and up-to-date
Site can be used as a stand-alone module or can complement a structured class
Content is well organized for learning
Concerns:
Users need a background in anatomy to make sense of the images
Some eclectic content in each region (i.e., a few video lectures and drag and drop exercises which are OK, but some regions have them and others do not)
Users would find it useful to have an home page based introduction on how best to use the modules
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
Learning objectives are clearly stated
This material is great as a review or supplement while enrolled in a course in human anatomy
Modules are interactive and engage the student as they complete the tutorials
Modules encourage critical thinking and problem solving as the student works through the material
Site contains multiple examples of X-rays, MRIs and cadaver images, and contains concise explanations of the images
Contains a variety of quiz and practice questions for students to review
Angiograph movies showing the flow of blood through arteries and veins create student excitement
Concerns:
It should be made clear to user that it is a supplement
Neuroradiology lab exercises would be more helpful if there was a labeled and unlabeled stack of images
Most quizzes and practice questions do not provide constructive feedback
Quizzes do not keep a tally of correct and incorrect answers; the learner must keep track of their own scores
At the time of this review, some of the self-assessment tools have not been completed for the site yet
Ease of Use for Both Students and Faculty
Rating:
Strengths:
Navigation was intuitive and easy to manipulate
Regions are sub-grouped for easy location of specific structures
Concerns:
Videos can take a long time to load if Firefox is not used
