As the saying goes, “A picture is worth a thousand words.” While it can take hundreds or thousands of words to convey a complicated concept; a single image can easily do the same thing. OPEN-i® is the open access biomedical image search engine from the National Library of Medicine’s Lister Hill Center for Biomedical Communications. OPEN-i® is unique in its ability to index both the article’s text and images from the open source literature and biomedical image collections. OPEN-i® searches and retrieves both abstracts and images (including charts, graphs, clinical images, etc.)
You can conduct a search in OPEN-i® by typing your terms in the search box or by selecting a saved image. From the results display, hover your cursor over an image and a MEDLINE citation will pop-up.
The following limits can be applied to your searches:
- Rank By (Newest, Oldest, Diagnosis, Etiology, etc.)
- Article Type (Abstract, Book Review, Brief Report, etc.)
- Image Type (CT Scan, Graphics, MRI, etc.)
- Subsets (Basic Sciences, Clinical Journal, Ethics, etc.)
- Collections (PubMed Central, Indiana U. Chest X-rays, USC Orthopedic Surgical Anatomy, etc.)
- License Type (Attribution, Attribution noncommercial, Attribution noncommercial no derivatives, etc.)
- Specialties (Behavioral Sciences, Biochemistry, Cancer, etc.)
- Search In (Titles, Mentions, Abstracts, etc.)
OPEN-i® contains over 3.7 million images from about 1.2 million PubMed Central® articles; over 7,400 chest x-rays with over 3,900 radiology reports; 67,500 images from the NLM History of Medicine collection; and over 2,000 orthopedic illustrations, plus MedPix.
Images are obtained from the following sources:
- The Open Access Subset of PubMed Central (PMC)
- The Indiana University hospital network
- The Orthopedic Surgical Anatomy Teaching Collection at the USC Digital Library
- Images from the History of Medicine Division from the U.S. National Library of Medicine
