Hello all, While going through the dataset and its csv file given, I was confused by some joint scores for erosion and joint space narrowing. When I look at the image of the patient UAB037's left hand, (According to the csv file, it is a normal hand, having all zero) I doubt that scores for mcp_1 and mcp_2 are really 0 because I can definitely recognize some narrowing in the image. (not sure about the erosion score though.) Is it just me or just a contrast issue? Thank you for your comments.
