Dermatology Times: Artificial intelligence diagnostics fall short in skin of color
UC medical student presents findings at scientific symposium
Dermatology Times reported research findings from Pushkar Aggarwal, a third-year medical student, in a recent edition. Aggarwal presented a research poster at the 17th Annual Skin of Color Society Scientific Symposium, which showed that a large gap exists in the accuracy with which artificial intelligence distinguishes between melanoma and basal cell carcinoma (BCC) in patients with pigmented skin (or skin of color) versus light-skinned patients.
Although, artificial intelligence can be a useful tool for dermatologists, significant challenges exist in creating databases and programming that provide equally precise diagnostic results in skin of color compared with lighter-skinned patients
Aggarwal’s research involved two image recognition models that were each trained on 150 images, validated on 38 images, and tested on 30. At each stage, the images were evenly divided between those that showed melanoma and those that showed BCC. One model was trained on light skin and the other on skin of color.
Aggarwal said that when the same number of images were used in the training, validation, and testing, the artificial intelligence model for skin of color still offered inferior results compared with the model trained on lighter skin, noting that current AI models will require significantly more images of skin of color. “Many skin lesions, especially those that are hyper-pigmented, are more easily distinguished from the surrounding skin in lighter skin color than in skin of color,” he said.

Did the ancient Maya have parks?
June 22, 2021
Researchers at the University of Cincinnati say Tikal’s reservoirs — critical sources of city drinking water — were lined with trees and wild vegetation that would have provided scenic natural beauty in the heart of the ancient Maya city. UC developed a novel system to analyze ancient plant DNA in the sediment of Tikal’s temple and palace reservoirs to identify more than 30 species of trees, grasses, vines and flowering plants that lived along its banks more than 1,000 years ago. Their findings painted a picture of a lush, wild oasis.
