An image uploaded of a patient with alopecia areata, an autoimmune skin disease resulting in the loss of hair on the scalp and elsewhere on the body. The angle of the photo ensured the patient remained anonymous. The app also requires users to obtain permission from patients before posting.
Images of test results, symptoms, X-rays and scans can be posted for consultation from a global pool of experts as well as to train others using the app. Here, a photo of red cerebrospinal fluid is uploaded. Blood in the fluid may be a sign of bleeding or spinal cord obstruction.
When users upload an image, any identifying information is removed before the image is posted. Here, an X-ray of a patient's veins, known as a venogram, is uploaded for consultation.
Users working in health professions are able to comment on images posted to the app either out of interest or to impart their wisdom to help with diagnosis.
