The internet era gives clinicians unprecedented access to clinical images for learning and teaching purposes – and no matter how old some of us may be, we all remain students until the end.
Here are some useful clinical image collections for use primarily by doctors in emergency medicine and intensive care medicine. Of course, we being disciples of the ‘Open Source Messiah’, the emphasis is firmly on free-to-use resources.
Clinical Image Collections Online
Clinicalcases.org – The definitive online case-based medical learning website includes links to the best images from some of the major general medical journals -especially the NEJM, Lancet and BMJ. The site is organised by specialty with a link to the images below the lists of cases. Here are the clinical image specialty links for ready reference:
- Cardiology — Endocrinology — Gastroenterology — Hematology and Oncology — Infectious diseases — Nephrology — Neurology — Pulmonology and Critical Care — Rheumatology
- Catalog of Clinical Images — UCSD’s exceptional collection of photographs of physical examination findings organized by anatomical region.
- HEAL — Health Education Assets Library (HEAL) is a hugely impressive digital repository that allows medical educators to discover, download, and re-use over 22,000 medical education resources, including images and videos. Registration is free.
- Trauma Image Database — A categorized collection of trauma-related images from Trauma.org.
- PhotoRounds — Brief ‘test yourself’ clinical images best viewed as ‘unknowns’.
- Eye Atlas Online — A beautifully presented database of images of eye diseases crafted in Italy. Ted Montgomery’s eye images are also a great resource.
- DermisNet, DermNet, and DermNet NZ – Being such a visually-orientated specialty it is not surprising that there are an abundance of quality dermatology image collections out there. These are my favourites for when I need to clinch a diagnosis of ‘aplasia cutis congenita circumscripta‘…
- MedicalPix and Medical Multimedia Kits are two great resources for 3D animations, videos, PPT backgrounds and clinical image databanks
Clinical Images from Medical Journals
No journal subscriptions are needed to access any of these high-quality resources:
NEJM Featured Images in Clinical Medicine — the classic web-only series from the New England Journal of Medicine – alternatively, try the addictive NEJM Image Challenge.
- CMAJ Clinical Images — The search results for ‘clinical images’ – open access classic, dramatic or note-worthy clinical images from the journal of the Canadian Medical Association.
- Clinical Pearls: Photographic Case Reports — a collection from the journal Academic Emergency Medicine.
- Diagnosis at a Glance — The entire series from Emergency Medicine.
Clinical Imaging — Radiology and Ultrasonography
EMPACS — Emergency Medicine Picture Archiving & Communication System – This is an impressive resource providing annotated images relevant to emergency settings from all modalities (USS, XR, CT, MRI, etc). Registration is free and all images may be reused if appropriately referenced to empacs.org. It even features a quiz mode.
- On Call Radiology — A set of teaching files to identify common radiology findings on call and in the Emergency room. The site includes an image catalogue.
- Ultrasound Guide for Emergency Medicine — The Image Browser doesn’t have many images, but too cool to leave out. Furthermore it is only a small part of the best online resource for emergency medicine ultrasound currently available (reviewed here on LitFL).
- Ultrasound Village — the pre-eminent Australasian Emergency Medicine ultrasound website.
Other radiology resources:
- Cases from The Radiology Assistant — This Dutch website is impressive… Its a great way to learn radiology.
- LearningRadiology.com — There is a massive ‘Case of the Week’ archive as well as an image index.
- Interpretation of the ICU Chest Film — An excellent beginner’s guide to the sometimes bewildering chest film in intensive care.
Pediatric radiology resources:
- Radiology Cases in Pediatric Emergency Medicine — an aging but otherwise impressive set of teaching files from the University of Hawaii.
- Pediatric Radiology — A collection of annotated images from the Cleveland Clinic that covers the core curriculum required for pediatric radiologists.
- Pedrad.info — Pediatric Radiology information, publication and communication platform. Includes an Index, Case of the Day and Most Interesting Cases.
Pathology, Microbiology and Parasitology
- PathWeb — it is no small mercy for docs in the ED and ICU that we rarely have to look pathological specimens, but if you ever need to, this massive database is a good place to go.
- DPDx Parasite Image Library — A superbly presented collection of parasite images from the CDC.
- Malaria— – An excellent resource from Royal Perth Hospital for learning how to identify malaria parasites on blood films.
