The National Library of Medicine hosts MedPix, which is a "searchable online database of medical images, teaching cases, and clinical topics." As of this write-up, this collection includes almost 54,000 images, including x-rays, photographs, and more, which visitors can explore by conducting a text search. Visitors interested in exploring the collection can browse by diagnosis, which are organized alphabetically. For example, those interested in learning more about ACL tears can view five x-ray images of this injury, accompanied by information about each image's source and, when possible, information about the patient (such as age) and their specific injury. In total, this collection includes almost 20,000 patient cases. MedPix was designed as a resource for current medical practitioners as well as medical students. MedPix also offers a free Continuing Medical Education (CME) course for current medical practitioners.
